Where Does WiFi Fall into the Ham World?

Brian Connors KB1KKC (W6NNABE) on November 11, 2004
View comments about this article!

It seems to me that much of the interesting work these days in the amateur radio world isn't being done by hams at all, but by people working within the Part 15 limits of the 802.11 world, dealing with antenna design, signal connectivity, and the Last Mile problem.

Spokane, WA is running a citywide WiFi system, and there are countless wardrivers and guerilla networkers who are contributing valuable information on signal propagation and infrastructure design. It seems to me the WiFi hackers of the 21st Century are the spiritual heirs to the tradition of packet radio, so why do we see so little discussion of WiFi technology within the circles that contribute to places like eHam? Are these people not radio amateurs just the same as us, with or without licenses?

WiFi Yes, Hackers NO!

If they have to HACK into that Spokane WiFi network then these "wardrivers and guerilla networkers" are NOT "radio amateurs" through their actions, and are NOT spiritual heirs to anything except the long-standing traditions of theft and vandalism!

If you have a public network with legitimate unrestricted access, sure they are free to tinker with it all they want to. However, just because the limits of Part 15 are observed does not make breaking into a network legal or ethical.

I've got a WiFi LAN at home, and have to run 256 bit WEP to keep out unwanted visitors and drive-by networkers (a neighbor kid broke my 128-bit WEP). Even that level of security won't keep out someone with lots of time, a WiFi laptop, and some network busting software that is available on the Internet.

Nearly all radio amateurs are strictly legal in their operating and methodologies, and are not brothers-in-arms with hackers. Having enough knowledge of electronics, propagation, antennas, and standards specifications to break into controlled and half-secure communication networks is certainly not anything to be proud of.
 
our bands, their interference

I am sending this message via an 802.11 link, so, I know how useful the technology is. I hold a patent covering a technology key to the widespread deployment of 802.11, and I am also a contributing member of the IEEE standards body working on WiFi.

That said: Propagation on (and antenna construction techniques for) the 2.4 GHz band is well known and documented. WiFi users do not add any new knowledge in this area. In fact, they routinely ignore and violate Part 15 with their illegal modifications to equipment, which then intrude into amateur radio spectrum.

Sorry. While a small minority of the computer network folks might become good hams, most are just interested in skirting alternate, legal means of establishing connectivity. Bad news is bad news, even if it only has a 300' range. Would you ask people who hack their cordless phones to double the range, illegally, to come to your next testing session? I didn't think so. There's little difference.

You may wish to look at the ARRL's program to encourage experimentation in this band by hams and hams-to-be.

The computer crowd is struggling with ethics. many of the younger computer users learn to hack before they learn that it is wrong to do so. If I am not mistaken, we by virtue of the license are able to make certain modifications to our equipment. The wifi is a non licensed portion of the spectrum and therefore, I believe not suppposed to be modified. Why is it so hard for some folks to stay within the law.

If I am wrong here please help me out.

"The wifi is a non licensed portion of the spectrum "

Check your band charts and you'll find that most (if not all) of the spectrum used by common 802.11 data is allocated for use by Amateur Radio.

I use my 802A/b laptop all over New york city.
Plenty of people have set up Free Publc Access to WI-FI.

Many colleges have non WEP systems.

This one dude wired up all of Central Park for WI-FI.

Yes, if your on a non WEP system you risk being hacked.

802B(7 channels) are like public water fountines.

I am involved with a group of Hams and others that want to make more free WIFI.


It is good for the information age, and hopefully will make BPL undesirable.

I do not condone ripping off someones system.
802B can be free legally. Only problem is you have zero expectation of privacy. It is not a panacea.

Tom, Thanks for the info. What about the modification for the equipment? I belive that hams are allowed to make some mods to there equipment. I am not sure about wifi? Are they allowed to modify the equipment?

I run wifi here at the house and love it. I ran large computer systems for years and it is great to be off the wire. I do however protect myself by using firewall, WEP and MAC filtering to prevent theft of bandwidth and hacking of my system. This is not fool proof but it is a layer of security. To do any less is irresponsible.

They may be radio hobbyists, but they would not make good hams because (a) they probably wouldn't want to be forced to operate within the confines of the ham license, and (b) they probably don't have the patience that ham radio requires.

Radio communication for the sake of radio communication--that is, amateur radio--is not really very interesting to them in comparison to the applications of WiFi and the access to the Internet they desire.

Tim,

The ARRL bandplan encourages us to use one of the WIFI channels (I think it's channel 7, but that's from memory)and use our callsigns as part of the SSID. There no reason we can't modify equipment and experiment with the technology.

WEP and MAC filtering are good starts but easily spoofed. I need to take a look at my WIFI access point and see if there's a way to turn off the broadcast SSID and make the network "invisible".

A local WIFI ISP in my area did a site survey around my house. 135 networks--88 wide open. Most peole set up the networks using the default settings for security. I wonder how many even bother to change the default passwords?

"WiFi users do not add any new knowledge in this area. In fact, they routinely ignore and violate Part 15 with their illegal modifications to equipment, which then intrude into amateur radio spectrum."

Ahhh, yes... Riding that high & mighty horse of exclusion?

- This is the very reason why we are minimized & the FCC forced us to SHARE the band because of bratty attitudes shown here from the start. WiFi'rs are clearly putting us to shame when literally millions are using our packet technology to move the world forward while bitter hams sit with 9600 baud packet from 1983 & are content with it but jealous of others. If you think holding a license is proof of technical competency, you obviously don't have a clue or are intentionally blind to reality. There are 25 hams in my county yet there are over 500 Access Points, do the math rocket scietists!

"Nearly all radio amateurs are strictly legal in their operating and methodologies, and are not brothers-in-arms with hackers."

- You're either in denial or don't operate often. Tuner uppers, 2KHz "wedging", "nets on schedule", UnID'd comments & general absurd behavior has taken over the bands along with the ever present "What's YOUR call?" How many hams have been caught jamming "public service" frequencies or each other? Oh yea, highly ethical hams...

"Having enough knowledge of electronics, propagation, antennas, and standards specifications to break into controlled and half-secure communication networks is certainly not anything to be proud of"

- A ham license test is far from a proof of knowledge because 50% of Extra-lites can't even solder a pilot light! Appliance operators have no WEP but I'd bet they easily become hams.

The entire tone of this thread is rather embarrassing. How can we attract interest when it is so far from reciprocal? Resentment is no equal to respect. I respect geeks but quickly losing respect for hams because of old attitudes that simply haven't died although they should. Being "patient" with ham radio is accepting yesterday's standards as "good enough" for today & not planning a push for tomorrow. Just look at CW!!!

Viva la WiFi, WiMax & 802.Xx geeks!

Radio control pilots use radio frequencies to accomplish their task but they are not considered radio amateurs - so why should a WiFi user be considered one?

WiFi allows users to communicate using a set transmission protocol with and without encryption.

Radio amateurs can change transmission modes and frequencies which is a horse of a different color.

by the way, try using WPA encryption with TKIP. That is a much stronger method of encryption that your neighbor kid will pull his hair out trying to decode your key from about 150 million different possibilities.

Word of Caution..

You are not permitted by the rules to use that device to transmit internet "commercial" content over that device if it is regulated as a part 97 amateur radio device.

Part 15 devices on the other hand do not have this restriction.

you might want to rethink the use of your callsign on the SSID of the device, especially if your using your Wifi device for any "commercial" interests using the internet.

Remember the "Using a repeater to order a pizza" scenerio?

Also the use of any digital "encyption" code may not be permitted unless the code is "publically" documented under part 97 rules. Most encyption methods used by manufacturers for Wifi devices may be proprietary and may only be distributed under license. In other words, the encyption code is non public.

Any other thoughts?

Glad to see you got a license Brian! As you might have guessed though, the original WiFi Systems were designed and built by Ham's. Some Ham friends of mine built the first system better than two decades ago. They installed it in the city of Cupertino. You may have seen photo's of some of their original units, it was a cute idea.

They used existing street lamp poles, both for their height, security, and the easy availability for power. The unit was slung below the lamps cross arm with it's whip antenna pointing down, they built a nifty little power plug adapter that plugged into the socket where the lamps photo-electric relay switch was inserted. The whole installation per unit took about 10 minutes each. I can't quite remember the name of their company, and I'm not so hard up for a date either, so as to take the time to research it. You should be able to find them though.

Isn't Ham Radio just more fun and exciting than 'war-driving!' Think about it, 23,471 MHz of spectrum using pretty much any mode you like. Wow, who wants to futz with Pringles can antennas, when they can build real radio stuff! Duh, real Ham's I guess.

Good numbers to ya out there Bubba! Your wall to wall and tree top tall on that Pringles can!

You are correct about the non-commercial use of an amateur 802.11 link. I'm sure the "ordering a pizza on the repeater" thought process will be hashed out down the line. If my memory serves me, that decision was left to the individual control ops rather than a blanket ruling that it was "commercial use" and not authorized.

The ARRL is recommending we use the eSSID to ID.

There is much experimentation happening in this area. I did note that WEP was okay using a published HMSS Key.

Loads of room for much discussion on this issue!

73 de Tom, K4NR


From the ARRL Website:

The ARRL Enhanced IEEE 802.11 Project calls for operation of the basic IEEE standard by licensed amateur radio operators in the upper part of the 2.4 GHz band while not significantly interfering with other amateur radio activities on that band or Part 15 IEEE 802.11b operation in the band. Under Part 97 of the FCC rules, amateurs are allowed to run many times the power of Part 15 operation as well as use antennas with unrestricted gain.

IEEE 802.11b channels 1-6 fall totally within the 2.4 GHz ham band. We are recommending that channels 2-5 be used for IEEE 802.11b operation as they do not interfere with other normal amateur radio operations in the band and are not on channels widely used by Part 15 operations. We recommend that channel 5 be used as the primary channel for general ARRL 802.11 network operation.

SNIP

...we are working on some IEEE 802.11b issues such as all station use "hsmm" as their SSID, and their amateur callsign in any second SSID (eSSID) or node/AP name.

Actually, this assertion regarding "unspecified codes" is a little off. The "codes" referred to here are essentially the "protocol" - i.e. Baudot, PACTOR, GTOR, etc. $$97.309(b) says (in part):

"RTTY and data emissions using unspecified digital codes must not be transmitted for the purpose of obscuring the meaning of any communication."

Now, WEP (or any other encryption) would be an unspecified code. Since it would be easily argued that it is being used to obscure the meaning of the communication (even if you argued that it was for access control), I am confident it would be found in violation of $$97.309(b).

I work in the WiFi Security space professionally; there is no solution that will adequately protect a "Part 97 WiFi" installation from malicious use, much as there is no mechanism to protect a repeater from malicious use. MAC filtering and disabling the SSID broadcasts are really all you can bring to bear while still remaining compliant with Part 97, and, as already mentioned, are bypassed trivially.

The real difference here is that unlike a repeater system, the general public is using the same equipment as we are; thereby exposing us not only to the usual repeater-jammer type, but to the computer hacker that doesn't play in the normal RF world. Therefore, your interference (hacking) probability is sky-high from the outset.

I don't have any solutions to offer at this time. From a security point of view, the only security our AX.25 packet networks, repeaters, and HF enjoy would be called "security by obscurity". Remove that, and you open yourself up to the same miscreants that have made the Internet a security nightmare. Or, to analogize in perhaps more familiar terms, it's like having the next FRS service share the 2m band.

Some people appear to believe that ham radio is simply a utility by which to connect computers. "Radio" is not the goal; instead, talking between computers is. To me, that makes computers the hobby, not ham radio. And for many of those people, if not most of them, if a better, faster, cheaper method of connecting computers is available, they'll use it.

We need to decide if ham radio is a hobby, or simply a means of conducting some other hobby, i.e., computers and the internet. If it is a utility, eventually it will be governed as such. If we figure that 300 foot communication by WiFi is the hobby of ham radio, then so are cordless phones, garage door openers, home security systems, keyless entry to automobiles, remote operated house lights, and PLC.

I'm all for encourging WiFi users to become Hams, but realistically I'm not so sure we have that much to offer them. As far as I can tell, WiFi enthusiasts are primarily motivated by the desire to have wireless Internet access at 'reasonable' speeds (these days meaning at least 128kbps, and preferably more like some-Mbps). The hardware experimentation is limited due to the complexity of the radios. At the end of the day, these folks want to be able to surf the Internet and still read their e-mail, make purchases on Amazon.Com, and, yes, potentially visit porn sites as they wish without anyone telling them otherwise.

Some of the people doing all this are interested in the technical aspects of, e.g., radio design, modulation, propagation, etc., and amateur radio has something to offer them there. On the other hand, when it comes to Internet connectivity -- their main goal -- amateur radio tends to be far more restrictive and much, much slower than what they already have.

It's market speak. WiFi = "Wireless Fidelity". Means the network interface between computers is radio based, rather than wires.

A lot of local-area networks (LANs) now use 802.11b standard RF networks. This is great for building area nets and laptop users, since the laptop can be connected without being physically teathered. Means I can walk into a meeting with my laptop and still be on line.

802.11b is only one of a family of 802.11 wireless protocols. These days 802.11g, which is faster, is becoming popular.

Just did a wardrive this afternoon, using a 7dB magnet mount & a 200mW Senao card:

Here in rural South Central Virginia, my county has 25 active hams at the most, yet I logged 155 Access Points in just 1 of 5 towns. 11 were WEP'd. 75% were defaulted to channel 6 & no changes made to anything.

Well, now that I've seen some of the responses, I should give my own position. (Note that I use "hack" in the nonintrusive sense -- wifi hackers are people trying to get the most out of 802.11 equipment, not necessarily trying to break security.)

What it comes down to is this -- radio is mainly about communications. What the wifi hackers are doing is finding ways to get a miniscule signal to propagate as far and as effectively as possible, and to that end they're bringing new interest to microwave engineering. They're the ones doing the homebrew antenna projects, trying to figure out how to milk that last dB of gain out of an antenna; essentially, they're trying to get the most out of microwave QRP. And they're doing all that with type-accepted off-the-shelf equipment.

Okay, so it's only one mode, a form of packet radio. But I still think there's enough ingenuity and original thinking going on to accept the wifi hackers.

There's an awful lot of painting with broad brushes going on here. Most people involved in wireless networking aren't hackers any more than most hams are QRMers. Yes, both communities are plagued by a small number of sociopaths and poseurs, but we've suffered similars fools since the dawn of telecommunications.

There are huge opportunities for hams to innovate with wireless technology, but connecting consumers to the internet isn't one of them; part 97 precludes this, and anything new would require enormous differentiation to gain mind-share. But mesh networking, peer-to-peer protocols, compression schemes, location determination -- all of these could be pursued by hams with cheap off-the-shelf hardware operating under part 97 on amateur bands.

Most of the communications revolution is in front of us, not behind us.

I use "hacker" in the sense of someone who likes to do interesting things with the equipment. It's actually something of a compliment in the computer world, and that sense (more or less the original sense of the word) is coming back somewhat. I refer directly to the O'Reilly title Wireless Hacks, whose hacks are all about things you can do with your 802.11 installation and how to do them and nothing to do with trying to compromise someone else's network.

W6NNABE, I don't mean this as a 'put down' but, how old are you? I am thinking that your just not old enough, or maybe not experienced enough, to look at "RF" as a widely dynamic engineering pursuit.

Thats cool though! It's good that you are seeking broad perspective. I just think you need a little more experience.

Don't get me wrong, I enjoy this hobby profusely, but this narrow-minded, holier-than-though crap has got to go to the wayside, folks, lest we wither away into a sidebar in the history books.

While companies like Intel are producing 10 GHz xvcrs the size of a microprocessor, what are we doing? Flaming people who have an interest in a certain aspect in radio but who aren't hams. Get off your high-horses, and look at this as a marketing opportunity. There is a direct correlation between today's crackers (They're certainly not hackers.) and tomorrow's hams. Let's be true to the Amateur Tradition and show them the way, not our nostrils. Have fun. I hope your boat anchor keeps you warm this winter.

P.S. By the way, the overwhelming majority of War-Drivers are true to the hacker-ethic. They merely seek out the networks and indicate their potential flaws. No intentional connection, no intentional "theft of service," no breaking into computers on the wireless networks' network. Don't assume everyone enjoying this niche hobby is a malicious fool like the media stories love to point out.
 
Where Does WiFi Fall into the Ham World?

Let's clarify things ...

From "The Jargon File" published by Eric S. Raymond:

<i>hacker: n.

[originally, someone who makes furniture with an axe]

1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary. RFC1392, the Internet Users' Glossary, usefully amplifies this as: A person who delights in having an intimate understanding of the internal workings of a system, computers and computer networks in particular.

2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming.

3. A person capable of appreciating hack value.

4. A person who is good at programming quickly.

5. An expert at a particular program, or one who frequently does work using it or on it; as in ‘a Unix hacker’. (Definitions 1 through 5 are correlated, and people who fit them congregate.)

6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example.

7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations.

8. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence password hacker, network hacker. The correct term for this sense is cracker.</i>

Compare with:

<i>cracker: n.

One who breaks security on a system. Coined ca. 1985 by hackers in defense against journalistic misuse of hacker (q.v., sense 8). An earlier attempt to establish worm in this sense around 1981--82 on Usenet was largely a failure.

Use of both these neologisms reflects a strong revulsion against the theft and vandalism perpetrated by cracking rings. The neologism “cracker” in this sense may have been influenced not so much by the term “safe-cracker” as by the non-jargon term “cracker”, which in Middle English meant an obnoxious person (e.g., “What cracker is this same that deafs our ears / With this abundance of superfluous breath?” — Shakespeare's King John, Act II, Scene I) and in modern colloquial American English survives as a barely gentler synonym for “white trash”.

While it is expected that any real hacker will have done some playful cracking and knows many of the basic techniques, anyone past larval stage is expected to have outgrown the desire to do so except for immediate, benign, practical reasons (for example, if it's necessary to get around some security in order to get some work done).

Thus, there is far less overlap between hackerdom and crackerdom than the mundane reader misled by sensationalistic journalism might expect. Crackers tend to gather in small, tight-knit, very secretive groups that have little overlap with the huge, open poly-culture this lexicon describes; though crackers often like to describe themselves as hackers, most true hackers consider them a separate and lower form of life. An easy way for outsiders to spot the difference is that crackers use grandiose screen names that conceal their identities. Hackers never do this; they only rarely use noms de guerre at all, and when they do it is for display rather than concealment.

Ethical considerations aside, hackers figure that anyone who can't imagine a more interesting way to play with their computers than breaking into someone else's has to be pretty losing. Some other reasons crackers are looked down on are discussed in the entries on cracking and phreaking. See also samurai, dark-side hacker, and hacker ethic. For a portrait of the typical teenage cracker, see warez d00dz.</i>


I consider myself a hacker because I work on open source software build complex websites. I have no interest in defacing or breaking into systems. Ham radio is hacker culture before there were computers. We have convieniently forgotten that fact. Back to your regular eHam discussion thread. Troll on!

Wardriving is not doing any illegal or shady really. now breaking wep keys and accessing networks with out permission from the network owner is something entirely different. So please do not lump all wardrivers in to the category of crackers, phreakers and the rest who do harm in their practices. To do this would be like saying all Hams are old men who do not do anything but harp about new technology and only use outdated technology for nothing more than a hobby practice that should have long since been put to pasture.

[I'm quoting a lot of different people here, sorry for the confusion this will cuause]

>WiFi experimenters of 2004 are not unlike wireless
>experimenters of 1904.

Mmm... I think there's one big difference: In 1904, the average 'wireless experimenter' had a decent shot at significnatly advancing the world's collective knowledge about wireless communications. In 2004, while it's certainly not _out of the question_ that a WiFi experimenter would do so, it's _far_ less likely: WiFi is already built on top of _very_ complex communication techniques. The simple fact is that relatively few people understand that complexity, and hence the likelihood of increasing knowledge in the are is greatly diminished.

>Wouldn't it be cool if,
>instead of treating them like bandits or

I don't think anyone's suggested treating them like bandits, we're trying to figure out how to best attract them to amateur radio -- if there's a point in doing so.

Yes.

>microwave QRP.

The problem is that it's one heck of a lot harder to figure out whether or not you're actually making improvements to that microwave QRP system when your main indicator is some highly filtered 'signal strength' indication from software on a PC. I think the amateur radio microwave guys have it right in that they start with spectum analyzers or at least CW when they're trying to make system improvements -- it gives much more immediate feedback.

Look at the specifications on www.cantenna.com for their main product:

Frequency: 2400-2500 MHz
Gain: 12 dbi
Beam Width: Approx. 30 degrees
Impedance: 50 Ohm
Max input: 50 Watts
VSWR: <1.5:1 avg.

Uh huh. What's the polarization? What's the shape of that beam -- is it symmetrical or not? Since when do people talk about 'average' VSWRs and not maximums?

These guys are not going to be submitting papers to the IEEE any time soon. :-) There's nothing wrong with that, but they're really in a different league than the W7PUAs and W8JK's of the world; it gets back to the idea that, no, these guys are not to modern communications what wireless experimenters were in 1904.

>And they're doing all that with type-
>accepted off-the-shelf equipment.

Well, not always! :-) There's a thriving market for 2.4GHz amplifiers out there, and I doubt a lot of them ever went through type acceptance.

>P.S. By the way, the overwhelming majority of War-
>Drivers are true to the hacker-ethic. They merely

I think most War Drivers are driven (pun unintended) by the desire to check their e-mail every 10 minutes and brag to their buddies about how many open access points they found. Standard teenager-crowd motivation for doing just about anything -- being popular! I do agree that most of it is perfectly benign. (Somewhat like 'stealing a kiss' from a woman many decades ago, before our cultural decided that that always constitute sexual harassment and will likely leave you in jail.)

I'm all for encouraging WiFi'ers to join the ranks of amateur radio, it's just unclear to me exactly what _we_ have to offer them. Regulations prohibit the main thing they're after -- wireless Internet access who no restrictions on the data being transferred, including whether or not it's encrypted. I will buy the argument that there's a lot that amateur radio could give to the WiFi'ers who are interested in propagation at 2.4GHz.

From the ARRL:

Quote:

While IEEE 802.11b allows WEP, an encryption algorithm, Amateur Radio transmissions are characterized as being an open media. That is, amateur radio operators expect and assume that their transmissions are being listened to around the world with no presumption of privacy. And, the FCC even mandates that hams will not encode/encrypt to obscure meaning.

I thought I read something about using a standardized WEP protocol at http://www.arrl.org/hsmm/wep.html but did not have time to do any further research.


I also found the following with seems to contradict the first:

Quote:

Thus, the HSMM Working Group respectfully asks the ARRL Board of Directors for their
support of this needed regulatory change and urges the Board to support the development and
filing of a Notice of Proposed Rulemaking (NPRM) permitting the use of encryption and strong

<Fred tends to filter out obnoxious jerks who troll QRZ, or who display a strong anti-ham attitude.>

As many, or more, others have voluntarily left QRZ due to Fred's attitude. Fred has a right to do what he wants, of course, but his attitude has become very narrow minded and monocratic resulting in unexplained banning and guilt by association.

QRZ has now become a reflection of Fred's morals. eHam is still the best place to get all the views on a subject as it remains a true open forum.

The QRZ database is incomplete, as it only includes hams that have not treaded on Fred's fragile psyche.

Now, back to our original subject...WiFi

I have to admit that I am not up on WiFi. Our city doesn't have it, but the city to the south of us does.

The question of whether or not we should embrace WiFi pioneers is a good one, but what about hams taking on WiFi as a new ground for exploration? The Internet was fertile ground and has been used by hams as a very good tool (anyone disagreeing will have to do so by sending me traffic on the ARES nets. Call K8MHZ QTH Muskegon, Michigan USA, or by snail mail, as a response on the Internet that hams don't use it would be considered silly :) ) and I think that WiFi would be great putty in the hands of skilled amateur 'sculptors'.

I contacted the VP of the wireless provider in the city that has it. It is about 16 miles to the nearest antenna. I asked if he minded if I tried building a high gain antenna to try to get into his system from here. He not only liked the idea, he told me what types of equipment people were using to get the best coverage. He also was interested in learning of my progress. When I first called him, I knew even less than I know now about WiFi but he filled me in the best he could.

Today's hams may not be able to build useable gear out of discarded trinkets (some can! I am talking about the average ham) but they know how to build high gain antennas, they know a little about probagation, they can do cool things like bounce signals, make computer programs to turn laptops into repeater controllers, etc. I think if today's ham tackled WiFi like they did the Internet, WiFi would be so widespread that BPL would have no marketable value.

Granted, WiFi exploration is no place for someone that thinks HF QRP CW is the answer to every conceivable question, but it is fertile, nearly untilled ground for the advancement of radio.

We need to realize that digital radio is here to stay. It is not just used for text comms anymore. The benefits of digital voice communications are demonstrated by digital cell phones. Do a little research. My Nextel can hit a tower 6 miles away from my basement with 600mW on a daily basis. Try that with a handheld. Analog voice systems will soon become a thing of the past in paid for communications. I assume it will stay with ham radio for another century.

Ham radio was once the forefront of communication exploration. I fear that we are heading toward becoming little more than a museum of same. We need to incorporate high speed digital communications into our bag of tricks and WiFi seems to be the place to do it.

Operators in our area have been struggling with Packet radio since before I got my ticket. To this day they can't provide for portable stations without a high failure rate. How can this compete with high speed Internet? It can, but it takes more tech savvy than I have. Why not replacing packet with high speed 2.4 gig digital Internet comms? The ability to transmit large amount of data, including pictures, in a short time very reliably is what people demand today. Amatuer radio operators have the license and skill to be able to do it without a utility conncection, if we decide to replace our digipeaters with high speed 2.4 gig repeaters. Since we would still be sending the same type of comms that we do with other modes, we would have no reason to struggle with encryption. I think it would be very impressive to most anyone to be able to use ham radio as a totally wireless replacement for parts of the Internet.

But then, what do I know? I have been struggling with CW for years and my brain keeps trying to make pictures out of it...

Stupid brain!!

Anyway, I think WiFi or similar could be a saving grace for amateurs.

And for the handful of you guys that will tell me to Just Learn the Code...Hey, I'm trying! I will get it, but I a) have little use for it other than passing my ham tests and b) don't have much time to do it because I spend too much time doing stuff like eHam and regular ham and work and run the kid around and clean up dog...

I'll stop there and say

"I think if today's ham tackled WiFi like they did the Internet, WiFi would be so widespread that BPL would have no marketable value."

This has been a point of mine since BPL showed up on the map long ago. I still see BPL as DOA, just look at SBC FTTX project, detailed today on dailywireless.org, which even mentions developing a "system on a chip". You can learn all about 802.11x, 802.16x & 802.2x wireless on that site.

Where has all the experimentation spirit gone? Having a license doesn't mean you know which way the signal comes out of the Pringles can!

Now instead of considering someone's opinion, research, experience & personal perspective, the kneejerks run to look up your call? How childish...

This whole thread says so much about our current desire to "advance the art".

Even that level of security won't keep out someone with lots of time, a WiFi laptop, and some network busting software that is available on the Internet."

Don't you use MAC level access lists on your WiFi access point/router? Short of modifying the hardware to clone the MAC address of the WiFi cards in your home, this blocks others from connecting.

I have my home WiFi LAN set up that way and have never had anyone access my LAN. I also use a distinct SSID that is not advertised along with 256-bit WEP encryption.

I have installed my Wifi behind my firewall router.

My network is therefore inaccesable through the WiFi transciever to my PC's.

This arrangement provides for additional security and keeps my networked PC's out of the "loop" through the "external" WiFi system.

Users that can hack past the WEP security feature on my Wifi transciever will only find themselves up against the router's firewall. They might access the outside internet connection, but thats about it.

They would have the same level of difficulty gaining access into my network from the "outside" using the Wifi connection, as they would if they tried it remotely from some place over the internet.

Not a likely proposition.

In fact, I can even leave the WIFi tranciever wide open with little worry. The worst case scenerio is that they might get access and use my internet connection.

Thanks for making that point. Yes, I do now. I foolishly thought I could lock my barn with a hasp and a nail, but discovered the hard way the only way to keep the horse thieves out is with real locks. In other words, WEP alone is not enough. Of course, MAC level access lists are not foolproof either, since anybody really equipped for hacking in can find a way through spoofing, if nothing else.

I would encourage experimenters to tweak or modify their hardware and software for new applications or better performance. My initial post here was based on the language used by KB1KKC, "wardrivers", "guerilla networkers", "hackers", all of which refer these days to individuals intent on defeating security measures and/or surreptitiously using services installed by and paid for by someone else. At one time "hacking" did mean about the same thing as reverse engineering, but the meaning has changed because of what many "hackers" did with their resulting information.

It's simply that I don't expect to have someone who is uninvited and unwelcome picknicking in my back yard, even without my knowledge. And it seems that the only solution is to build a bigger fence.

Joel (KE7CDV), There is nothing that limits these guys from doing similar researches (as some have claimed to be involved in) on Amateur Radio. In fact, there is a strong need for them to shy away from the toy RF stuff they are playing with, and do real microwave studies.

There is a lot of SHF spectrum out there that could be used for some really wide bandwidth high baud rate communication. The regulations do not prevent this! If they are worried about that, just drop an e-mail to the FCC to tell them the communication protocall they intend to use, and zipzap, go to town!

Lets look at this from a different angle for a minute. To paraphrase Brian's first thought (not to put words in your mouth kid) 'Wow, this WiFi stuff is really cool, Ham's should embrace this, afterall how else can anyone experiment with SHF'. He could have scratched his chin and asked himself, 'how could I build up a really cool broad bandwidth communications system, that would beat the pants off this WiFi stuff'?

Several years ago my club started to develop a high speed broad bandwidth 'Communications Data Project'. The system involved the use of 10 GHz Gunnplexer transceivers, of the type typically found in commercial door openers, like those found on the doors of grocery stores. These units provided about 20 to 100 mW into a Horn antenna with 10's of dB's of gain. We also found a collection of small parabolic dish antennas, about the size of a Frisbee, that would have added some 30 dB's to the RF end of the hardware.

We designed a very nice I.F. (thats Intermediate Frequency) circuit board at 50 MHz (another minimally utilized Ham band). These boards incorporated the power supply, and also the modulator for the Gunnplexer. Additional realestate was provided for on the PCB's to allow other logic circuitry to be easily built up by the experimenter. Also, the filter network on the I.F. could be unplugged on a DIP header, and replaced with a Murata 6 KHz bandwidth filter, so as to make the I.F. also a very cute little DX receiver on 6 Meters. I was laying out a 6 Meter transmitter board, waiting for replies to come in on the project.

We were offering the Gunnplexers free of charge for anyone who purchased an I.F kit. We were selling these kits at cost! WE HAD NO TAKERS! You can still find the write-ups of our plans on the Internet, do a Google search. The only interest shown was from some European Ham's that wanted only the Gunnplexers, which they would not be tax'ed into oblivion for importing, because those were scrap surplus. U.S. Ham's showed no interest at all!

I could go on to point out the fallicy in the idea that "Hackers", or "Crackers" are really a benign bunch but, I'm sure all these hackers have read, "Masters of Deception" by Michelle Slatalla and Joshua Quittner. This book sits on the shelf next to my Amateur Radio "Handbook", my Shrader on "Electronic Communication" and other books on radio and technology.

Hi,
Wayne K9DI es Leader Dog Riot here. I've been
reading this thread and one glaring error stands out.
The perjorative use of the term "hacker". Hackers are not evil or malicious. The malicious ones are known as "crackers".
The definition of a hacker is someone
wanting to learn, experiment and explore a subject (usually used in conjunction with computers). By this definition every ham that modifies a rig, makes an antenna, or just tinkers with their gear to get the best performance out of it is a "hacker".
A "cracker", on the other hand (like Kevin Mitnick), is someone that exploits known or newly discovered flaws in hardware or software to do malicious things.
The above definitions are loosely paraphrased from the original jargon file.

Wayne has a valid point.

I remember when I ran a BBS in the 1980's that the term "Hacker" was actually a person that was highly respected and knowledgable about early PC's and thier software applications.

I even remember one of the first computer stores I ever seen was actually called:

"Harry the Hacker Computers"

The name denoted a friendly place with knowledgeable staff.

Later on after the "Mitnick" case, the term "hacker" took a downturn because of the mainstream media's new interpretation.

I think the term "Hacker" was later replaced with the word "Guru" Essentially, they are supposed to mean the same exact thing.

Perhaps "Guru" will become a bad word someday just like "Hacker" did.

I AM A HAM THAT ALSO WORKS FOR A ISP.
WE HAVE BEEN INSTALLING 900MHZ, 2.4GHZ, AND 5.8GHZ WIFI
FOR SEVERAL YEARS.
IT SEEMS TO ME THE HAMS HAVE CLEARLY DROPPED THE BALL WHEN IT COMES TO WIRELESS DATA AND THESE BANDS.
WITH THE RF POWER LIMITS HAM'S ARE ALLOWED ON THESE BANDS, GREAT COVERAGE COULD BE HAD AT A REASONABLE COST.

The point is that the continuing jihad attitude is not serving the ARS.

It would be nice if that were true; and it is what Fred used to claim. But enough people have called him on the difference between his claim and the reality of the site, that he has recently taken to giving a more honest explanation. You get bounced if you 'piss off' (Fred's term) one of the moderators.

Glen, for examplle, flat out refused to sanction one of the most obnoxious jerks on the board, simply because he happened to agree with the jerk's position.

On the other hand, Glen banned contributors that Glen himself had identified as sticking to the issues, simply because he disagreed with them.

Fred, of course, has ever right to ban whomever he wants, but I'm glad that he's now at least being honest about why he bans people.

It's too bad that so many people seem to think that being allowed/banned on QRZ indicates anything other than a willingness to question sacred cows.

It's even sadder that so many people think that there's only one true view of ham radio and that expressing any other view is "strong anti-ham".

No Doug, I don't believe that ham radio has anything to do with EHAM or QRZ.COM. As long as there is income coming into the Gov't, there will always be a certain interest to have and to hold. We will have ham radio as long as the mfg's are in the need of income as well. Ham radio is built around money and when there are no longer any buyers of ham equipment, ham radio will diminish. My opinion and I take ham radio as I would a grain of salt as it is no longer ham radio but push to talk. These $10,000 radios are an example and as long as there are buyers, there will always be ham radio.

Then again, should ham radio become invalid, so what? We have plenty of new ideas and inventions to keep us occupied.

I heard from the grape vine that QRZ.COM could not composit and overloaded Fred's hard drive and he couldn't afford another. So Fred deleted a few dozen with sorrow, but it had to be done.

May be when he gets more donations he will take all those back that he deleted. I sure hope so and being the sort of gentleman he claims to be, I am sure he will give all a second chance.

Cessna-very pedestrian. Twin engine private jet is another.

Moving right along. I understand many have been kicked off of QRZ ,consider it a statement of free speech.

802b is built into every new laptop. One cannot help but hit the scan key. I get 3 open networks just by parking on WIFI CH-6.

If a system is open, it is public access. I did not travel in a car. I just turned on my IBM laptop and the open networks appeared on my screen in my apt.

Many that buy those 802B $70 routers from radio shack are just consumers. They have no interest in ham radio. I got tired of getting my modem card ripped out when I moved the computer. I bought a router for my own use.

No one has hacked me...yet. Many times it is just people's built in 802B auto activation, that end up in my router. I do not need 12megabit wide connections.

What many hams ARE doing to fight BPL, simply leave thier wireless router open. My electric company is going to offer BPL for $35/month.

Having an open system is not always ignorance.
My 802.b router always on, is a deterent to my neighbors getting BPL. Rat Shack also sells the booster amplifiers. I have no idea what the power output is.

That is where I see Ham Radio falling into WIFI as
BPL prevention. Nothing more, nothing less.

I also remember when a Hacker was just a hard working computer operator. They would look for open doors on the internet. They would do NO HARM.

The hacker of today is proud to be a silver collar
criminal. Very unfortunite indeed. Robin Hood gave back to the poor.

The silver collar hacker will move on to bunco, electronic credit card theft, and getting extra minutes out of stolen pre-paid cell phones.

As others pointed out 900MHZ, 1.2, and 2.4 gig were ham radio frequencies. Use it or loose it. The same could happen with HF. Perhaps the FCC will legalize those 100W 10-12M radio's. It would be like GMRS for truckers.

Try 10M from time to time. It can be great. It can be dead.

Bottom line is that any other under utilized band will be taken away.

WiFi is a 'kindred spirit to Ham Radio' -- give me a flipping break -- LOL! I have been to some of these Pringles can sessions. Its like, wow man, it really seemed to work better when I stood on my head! Thats their idea of 'signal propagation studies'.

I'm more worried about the Ham radio community though with comments like, 'try 10 Meters, sometimes it works good but, sometimes not. How about researching siganl propagation to learn about Sporadic E layer propagation, or how the Earth/Sun position works over the various months of the year and can enhance F layer skip, even as we decline in the 11 year sunspot cycle.

I liked AC0H's comment, basically begging the question 'why do we want people that are wedded to breaking the rules'. We have lost much of the SHF spectrum! We will lose more unless we develop really cool uses and practices on it ourselves. Of course, that does not fit easily into the new Ham Radio view on plug and play!

What this thread is showing is the ham radio community's unwillingness to get with the times, something they need to do if they wish to survive! There's nothing wrong with WiFi as a hobby. With ham radio, one could take advantage of their allocation here by using the higher powers we are allowed to use. Of course, the whiny, close-minded, and judgmental crowd will see 2.4 Ghz as kiddie-land to be avoided in lieu of the "real" 1200 bps VHF packet links the old-timers use...

*** High Horse Alert*** Where is wardriving defined as "trying to break into networks"?

AirSnort/NetStumbler is the automated logging of Access Points, SSID's, Signal Strength, signal-to-noise, channel & if the AP is running WEP. If you add a GPS to the setup, you can map the results of any signal survey using popular mapping programs. I use my laptop in the truck without ever having to touch anything, much like cellular drive testing.

No "breaking in" involved, no harm done. As someone already said, if you can associate to an open network, you are being invited to use the connection. What does ham radio offer in parallel that isn't at least 20 years old? Packet? : )

As a member in good standing of the CWA (the Century Wireless Association), I feel that no-code, WiFi and BPL will be the ruination of ham radio.

Of course, in 1910 I predicted that wireless telephony would be the downfall ot the radio hobby, and personally traveled to the home of Dr. Lee DeForest, set fire to a bag of dog poop, knocked on his door and ran away.

Following the second World War, against my stern warnings, ham radio operators began using single sideband. Suddenly our precious bands were filled with unintelligible gibberish. Were our government not busy with Korea and Joe Stalin's commies, they doubtless would have taken away our bands due to gross misuse and abominable operating procedure.

All the so-called "advances" from then to today have steadily chipped away at the cornerstone of amateur radio. Whole portions of our bands are now filled with odd bleeps, chirps and deedle-deedles that somehow translate into idle text chitchat when connected to one of those infathomable computing boxes. This union of electric calculating box and ham radio transmitters is surely the work of the devil, and a major contributor to the weakening moral fabric of our nation.

All you young whippersnappers seem to care about is "connectivity," as if ham radio was all about bringing people together. Of course, we true hams know that amateur radio is really about exchanging signal reports, gas prices, rainfall amounts, and minute details of our ongoing physical deterioration. That and spending the better part of every weekend screaming "CQ CONTEST" into our trusty old Astatics until we're blue from lack of oxygen.

Every day, at 3 pm, I join my honorable amateur friends in the Greater Springfield Traffic Net And Grim Reaper Roll Call, and for two hours a day we greet one another with a hearty round of "no traffic"s and "any further check-ins?" This is the true public service for which amateur radio was created, and we are proud to be on the ready in the very real likelihood that an emergency takes out every landline, cellphone, coaxial cable, fiber optic pipe, public-service repeater, and VHF handheld in the United States.

We carry on this thankless tradition while you young hoodlums are roaming around the neighborhoods in your trucks attacking the computing machines of people you don't even know with killer viruses and electric mail messages offering discounts on potions which unnaturally stimulate the male sexual organs.

You should be ashamed of yourselves. That is not the spirit of amateur radio.

Very soon my lifelong predictions will come true and we will all lose our wonderful hobby to a generation of tinkerers who have no respect for the countless hours we have spent sitting in our cellars saying nothing to one another.

Bah!

"No 'breaking in' involved, no harm done. As someone already said, if you can associate to an open network, you are being invited to use the connection."

CJ, the problem is that most of those folks who are running open networks do not know it - they just bought a WAP at Best Buy and a card for their laptop, and are unaware that any wardriver can access their open network.

There is nothing wrong with locating the networks, hunting them, measuring them, documenting them or whatever, but many wardrivers are looking for a network to explore. That is, to most people, electronic trespassing - just because they "left the door unlocked". They may have personal data on shared resources on their network, and think they are protected just because they have routers on their wireless and broadband links, and maybe some easily-breakable firewalls on their clients.

BTW, it's interesting how this thread has meandered away from WiFi and now borders on the future of amateur radio!

Exactly.

Most wardrivers roam around town trying to find WiFi hotspots which is fine and good. Most of them also mark the best signal spots. Why if not to come back to try and ILLEGALLY access the network?

This has nothing to do with an ISP, individual, or company, (Starbucks comes to mind) from offering their network freely. We're talking about people sneaking around with frequency counters, GPS recievers, and laptops trying to access closed networks. Plain and simple.

Right on, Steve. This is e-x-a-c-t-l-y why it is advantageous for Amateur Radio to find a way to embrace those who are exploiting the Part15 users of the WiFi frequencies. We have learned many lessons over the years...lessons that can be built upon.

1. --- Cellular radio and APRS are living examples of where high power and long distances for the purpose of uplinking users to a network are bad ideas. On the other hand, it's a great way to link "cells" of activity together...as a backbone.

2. --- FM Repeater sub-bands and their regional coordination are living examples of how to waste spectrum and setup unnecessary conflict. On the other hand, a national plan for digital spectrum usage could serve us well.

Why do WiFi DX enthusiasts do what they do? For the same reason we do what we do. It's fun and exciting. We are limiting our ranks by taking a "holier than thou" viewpoint of their activity.

Embrace the WiFi experimenters. They are cut from the same cloth. Elmer them into the hobby and inject more energy into your club than a bottle full of Geritol ever could.

Brien, sometimes you have to put the shoe on the other

Sometimes a repeater club may have had trouble with a chronic jammer. They paid for the repeater, duplexer, antenna(s) snd hard line.

If they also have to pay rent for the space the expenses can get very high. Lets say it is a 60W repeater. If they are in an area with lots of Imod,
they have to use a PL. It could still be public.
If it


If it is DPL, then chances are it is a private machine. You can set up your own repeater some day,
and be just as exclusive.

In NYC all repeaters have to use PL. So much IMOD that carrier squelch will not do. Most of the new radio's allow you you scan for the PL or DPL.

At least somebody is making used of the 13 cm (2300-2450 MHz) band. Hams are definitely not overloading it, that's for sure!

Comparing the 802.11b channelization, http://home.comcast.net/~sofa.spud/802.11_freqs/802.11freqs.html

with 13cm ham bandplans such as the one we have here in Canada, http://www.rac.ca/service/13cmrev1.htm

it can be seen that WiFi Channels 1 through 6 fall into our band.

We need to look into the WiFi transceiver cards to see if they are adaptable to any modes other than the OFDM that they use. Maybe it's not possible (single chip does almost everything), but it's at least worth trying...

Rather than fearing, rejecting, or bashing WiFiers as some have done on this thread, we really need to ask these WiFi experimenters how it's done.

They have innovated. Have you seen the Pringle's chip can waveguide antenna? Good gain figures. WiFiers came up with that.

Lots of good stuff is on the net about WiFi technology. Here is a site that includes a huge treasure trove of UHF/microwave ham radio and WiFi experimeters info and construction articles, at the Green Bay PPR site at http://www.qsl.net/n9zia/

Take it all in folks. If hams aren't using the bands, there are lots of other groups who are...

WiFi also operates in the 5.8 GHz band. WiMAX (see this month's CQ Magazine for a great introductory article by KA3JIJ) will also operate in 2.5, 3.5, 5.8, and higher bands, inside or adjacent to ham bands. it is the next coming wireless trend, and is just making it throuhg the international standards bodies now, and some companies are getting the technology worked out. Hopefully this will lead to cheaper, more readily available components and building blocks for hams to build on, just like military surplus did in the 50s and 60s.

There were a few posts about a zillion or two back that were talking about how some folks have "secured" their 802.11 networks from hackers/crackers/miscreants (choose your term).


Let's get a few things straight:


MAC Address filtering is ZERO security except for someone who is clueless about WiFi. Almost any WLAN card can be ASSIGNED a MAC address. In Linux, this is a trivial one-line command. Someone who wants to subvert your security will sniff your WLAN (easy!), get the required MAC addresses, and use one. Unless you monitor that WLAN 24x7, you will NEVER know.


To the OM who installed his WiFi outside his firewall and is happy that the only thing that can be accessed is the Internet, let me pose a few scenarios for you. Let me know which one you feel more comfortable with:

A. Your WLAN is used to send a zillion pieces of spam, causing your ISP to cancel your account.

B. Your WLAN is used to perpetrate an attack against a corporate or government network. It will be traced back to you. Or, maybe it's just used to launch the latest virus or worm.

C. Your WLAN is used to traffic in child pornography, which is then noticed as part of an FBI sting operation. FBI agents come to your door with a warrant and haul you and your PC off.


If you think that spammers, hackers/crackers, and pedophiles aren't doing this today, then I suggest a lengthy session of Googling.

Yes, no, and maybe. MAC filtering, by itself, only reduces your exposure slighlty. However, when used with other techniques, it helps. We only allow two MAC addresses here, and both machines are usually on. So if someone attempts a spoof, it become apparrent very quickly.

WiFi security sucks. Key size doesn't matter much, as there are bugs in key exchange protocols that can be exploited for replay attacks. There are proprietary tricks that help, but they limit you to one vendor's hardware.

As I've said, my technique involves reducing the range of my WAP, so that it can't be heard outside of house and yard. If you wanna use my wifi, you gotta come onto my property.

In your cogent description of "Real Hams", you forgot to include those of us who know "real" Ham radio so well that we no longer bother to get on the air at all.

Heck, most ;aof us "real" Hams don't even have a rig or antenna (the retirement home doesn't allow antennas, so why have a rig?).

We simply have our Ham Club meetings at our favorite restaurant and enjoy endless re-telling of the same "good old days" stories for the umpteenth time.

Now Im all stoked to read about the nitty gritty modulation techniques etc. Another friend of mine at work who is into digital communications, packet etc has been helping spur me along and now I just picked up my first HT since I gave away or sold off my gear about two years ago. Knowing basic radio theory really helps out and I cant wait as 802.11 progresses and I get to read about all of the killer inovations that it provides. Maybe one day I can find time to build some home rolled microwave digital gear.
IMHO, if you want ham to grow, make it relavent to the current generation. 802.11 and microwave communication has never been more relavent and embracing it and teaching people about ethics , antenna and rf theory would do more for the ham community then anything EVER has.

A quick tip, use WPA with radius, have it renew the key ever 5 minutes. That pretty much eliminates every applicable security exploit out there. If you are real parinoid you could use a VPN client/server and some clevor routing to nail it down even tighter. Dont allow excess coverage and make good use of directional antennas if you want to get in a certain part of the yard.
Just my .02, now back to the topic.

There are a few diffrent types of hackers...
There are those who try to get into systems for the fun of it. A good network admin might be called a hacker.

There are those who do it to steal information.

Some are called White Hat Hackers who are on the good side and report security stuff to the admins, then there are the Black Hat Hackers who are the bad people.
WiFi can be used for good things and bad. It just depends on who uses it I guest.

Check out 2600, 2600.com

And for those who say WiFi is NOT amateur radio, you better check your facts. Channels 1-6 fall right on the 2.4g band.


Hope this helps!

I am not saying all at all. I will often scan any location for an open NETWORK. No war-driven either.
All the 802a/b/g cards have a scan funtion for networks open to the public.

Some are open to attract customers, like STAR SCHMUCKS. Some are just so non savvy about their $79 blue box from Radio SHCLOCK. Plug and Play.
They have not a clue of who could mess them up, or steal sensitive info.

As with any radios, you can play "what IF..." all day. I could use a ham radio to communicate or to jam. Does that make all hams jammers?

The following statement, from NetStumbler's author, states his intent clearly to underscore more common ground than most acknowledge. This ground lies unclaimed by most of the folks posting in this thread:

{Shipley}: "Most recently I invented Wardriving, while I am not the first person to go out and search for open wireless LANS (a few before me ventured around with in a with a laptop, pencil & paper manualy scribbling notes). I was first to automate it all with dedicated software and a GPS. When I started this project the usage of WEP was around 15%, after going public with my findings, just one year later, WEP usage is now about 33%. This is good to know, that people are getting the message."

I am a computer guy and I use 802.11 technologies daily at home and at work. At home I even use it for amateur radio how you may ask. Well about 1000ft away from my house is my friends repeater. It just so happens that this repeater is on IRLP. I know many hams do not like IRLP and say that it is not radio however I disagree as I still use my radio to access it. To get this node on the air we use a 802.11 link. Not only do we run the IRLP through this link but we use it for VoIP (Voice over IP which is basically a phone line running across the internet). So basically from a 802.11 link we provide people with a way to talk all over the world and the use of a phone. In our situation we can not get/afford a internet connection and/or a phone line up on the site so this setup works great for us.

Well, once again I should have read the entire thread before my earlier content, because I am now embarassed to be part of this. More on this later.

The one thing I found interesting, in this "WiFI'ers vs. Ham's" debate is most of the serious WiFi'ers are hams operating under part 15. I did a poll of the BAWUG (Bay Area Wireless Users Group) and fully 40% on the list. And of the real mover's and shakers, 3 out of 4 held amateur radio licenses.

What this tells me is one simple thing. Our hobby has cancer is is being eaten from within. Those with closed minds who wish to re-live their childhoods of vacumm tubes and duck and cover drills.

Instead of trying to compare "WiFi'ers" to CB'ers (and how many of you came here from those ranks??) we should be embacing them. The state of amateur radio in the United States is a state of embarassment. Quick, how many of those new and fancy HF digital modes where invented in the U.S.? Europes regulations, and acceptance of alternate modes, is much greater then the U.S. and it shows.

Wake up dipshits.

"The state of amateur radio in the United States is a state of embarassment."

This is indeed true, along with denial & it is cultural in nature. I have found considerable ham movements in the UK & Australia on the web. Much of the tinkering going on is outside the US (UK, Spain, Poland, Australia, etc...).

In the end, it really seems silly to have to get a license that cuts your ability to fully utilize the utility of wifi.

We have a deep 'control' problem, driven by ruling over others, in an attempt to somehow seem 'superior'...

Part 15: No content or WEP-like restrictions, just ERP
Part 97: Higher power allowed but content restricted & no level of "security" allowed

Who are the CB'ers???

You can apply the security on top of any modulation schema. I have been very interested in playing with different modulation schemes since getting into 802.11 and then back into ham. I need to get in touch with that guy with the 10gig horn kits and see about getting one of those.
We need at least a portion of the ham community to lead the away again, in modulations, antennas, and pretty much anything microwave or related. Lets declare packet dead and do something really interesting like a network of HAM 802.11 esque nodes that blanket whole cities. Then we would have the infrastructure to do anything. Like anything else in the world for HAM to grow we have to stay relevant.

Maybe you should read the description better, then. They are certainly NOT computers. They USE computers, but they are not computers. Computers are a tool, nothing more. But using them maliciously, like the so-called wi-fiers, is against all that is good about ham radio. We should welcome them into our ranks only if they reform their ways.

As far as the "hacking" and "guerrilla networking" goes, a few people here are using the wrong defenitions of "hack" to jump to a negative judgement on the value of these radio hobbyists. THe author of this article means "hack" in the pre- "WarGames"-movie meaning, which was someone who liked to mess around with technology in non-traditonal ways. I think that THIS meaning has much in common with ham radio. The OTHER meaning of "hack" has more to do with pirate radio, cellphone services thieves, and people who jam others communications - i.e. the "bad guys".

SO, with that cleared up - A couple of years ago I started a group called BAWIA - Boston Area Wireless Internet Alliance - http://www.bawia.org - to promote and coordinate activity in the the area that the author speaks of. However, I have found a very low level of technical competance in the RF end of things in the group as a whole. We need hams! Ham radio also also needs the enthusiastic, young new blood that this movement offers. So I encourage this cooperation!

What I find alarming is among these hobbyists there is practically NO regard given to lightening safety - arrestors are hardly ever seen! Another thing I have been trying to educate people on is the RF loss in lengths of cheap cable at microwave frequencies. Many of the antennas sold at computer stores for home networking have long lengths of generic cable that is WAY too thin to give me any confidence that the small gain given by such a tiny antenna isn't wasted on the 15 feet of flimsy cable attaching it to the WiFi card!

A fun project for "hacking" on is the MIT roofnet software, which forms a self-organizing "grid" a.k.a. "mesh" network from old PCs with a wireless card. See http://pdos.lcs.mit.edu/roofnet and http://www.bawia.org/meshax

I think this thread relies on too many loaded words and phrases. We should cut through the underbrush and get to the underlying question.

Rather than terms like "WiFi" and "Wardriving", let's talk about the underlying technology.

"WiFi" is just a marketing name for a particular approach to very short range radio networks. These nets, collectively, fall under the heading of 802.11 -- an IEEE subcommittee, and the standards produced by that subcoommittee.

WiFi, and its competitor, bluetooth, were originally aimed at very short range networks. Originally, bluetooth was intended for "body area" networks, while WiFi was intended for building area networks.

But it is the nature of computing networks that "local area" grows to encompass as large an area as technically feasible.

For WiFi, this means attempts to grow beyond the few hundred feet implicit in the original power/antenna designs, and see how far such networks can be extended.

There are informal approaches, such as the infamous pringles can antenna, and there are more formal approaches, such as the consortium that is attempting to extend RF nets to the geographic scope that broadband networks currently have.

Is this relevant to amateur radio? It could be, but it doesn't have to be. If, as I contend, the amateur radio hobby is now about enjoying anachronistic means of radio communication, notably HF and VHF/FM; then there is no intersection.

If, on the other hand, if amateur radio is about being on the RF communications leading edge, as those who like to cite section 1a of the regs like to claim, then attempts to extend WiFi are very much fruitful grounds for both amateur radio hobbiests and for recruiting amateur radio hobbiests from.

After all, this is about as QRP as radio communications get, and it is, very much about things like efficient antenna design, and frequency sharing.

On the other hand, it is also about what is, in reality, the large gap between the state of the art in radio communications, and the state of the art as practiced in amateur radio.

Which path this hobby takes at this fork in the road is entirely up to the hobbiests. I predict it will go in the direction of nostalgia and anachronism -- and that's perefectly fine with me; since that's why I got involved in the hobby.

The only danger is to go down the one path while believing that the hobby is going down the other.

A computer is indeed a tool. So is a radio. Both are extensions of basic human capabilities -- computing, managing information, and communicating.

The combination of wireless connectivity and distributed computing is producing an explosion of new opportunities. Those who love glow-in-the-dark equipment, CW, and HF propagation are free to enjoy their nostalgia. Those interested in pushing forward are also free to do so, and ought not be held back by the need to demonstrate mastery of commodity technology.

Every transceiver built in 1950s incorporated parts made of steel and copper. Did amateur radio exams of that era require knowledge of forging steel, or smelting copper? Of course not; such parts were available off-the-shelf, and could not be significantly improved by amateur practitioners. The extrapolation to today's technology is obvious.

I wrote my first computer program in 1968, designed my first commercially-released computer in 1972, and started writing amateur radio software within months of getting my ticket in 1990. I love DXing on the HF bands, and will continue to do so until I've confirmed every DXCC entity on every band between 160m and 6m, and on phone, CW, and RTTY. I redesigned my SB-220 for 8-band operation before replacing it with an AL-1200, which only fails to glow in the dark because its tube is ceramic and its meter lights are long blown. Creating and maintaining the freeware DXLab Suite has taught me a ton about user-driven software development, and helped stimulate my thinking about wireless mesh networks that use WiFi and ultra-wideband to create a communications fabric we could never achieve at HF.

My point is that our hobby encompasses a broad range of interests, and they are not mutually exclusive. You're not personally interested? No problem. Just don't discourage those who are.

Actually, yes. At least the software image for my WRT54-G's using the SVEASOFT and EWRT distro's (based on the LinkSys GPL code). Also quite a number of antennas as well as one amplifier. I noticed you even bought your Windom, which is a simple wire antenna (one of which I homebrewed for my HF ham station).

"What kind of setup to you have for making the ICs?"

Yeap, figures. You'd be the appliance operator in the 1950's who would also asked the ham hacker of that era if he had refined the copper and mined the iron for the homebrew rigs of that era.

"Also have built several rigs over the years, both kit and my design (one of the kits is visible in the photo - the TenTec 6-meter rig.)"

Good for you. Then why all the basely accusations against hams that want to experiment with WiFi? You realize twice I have asked you to document your claims of law breaking, and twice you have ignored them.

Bottom line, if ham radio wants to survive, it has to be relevent to today's society. "WiFi hacking" and alliances with WiFi community networking groups can go a long way into making this happen.

Bottom line, we want people in this hobby/service who are inclined to operate within the rules. If "being relevant to today's society" means we must accept society's current attitude that laws are meaningless if I don't want to follow them (as in "Who are you to tell me to slow down in the school zone?") then we have only anarchy ahead ("the hacker ethic"). We have had some great people come in from the other lawless group, but have also had some real problems from some of them who do not want to follow the law. We don't need more.

As I said before, I welcome all who are really interested in the hobby/service. But only if they plan to operate within established laws and norms. I really don't understand why that is such a barrier.

Obviously your spell checker is broken then.

Take a few of these web pages to your next ham meeting, and tell me how many of the hams understand what these "wifi hackers" are doing:

and on and on...

Jim, you really need to get out of the house more. It is a brave new world out there, and at least in advancing the state of the art on 2.4ghz, ham's are being given a run for the money by the WiFi hacker's.

I for one think we should embrace them, rather then shun them like you seem to advocate. Of course they need to follow the rules, that goes without saying, but you've yet to cite any specific infractions you have observed.

All barbs aside, ham radio embraced "cb radio", like it or not, back in the late 70's. There is no comparsion between the "WiFi hacker" and the CB'ers of the 70's. WiFi hackers are far more technically knowledgable then the CB'ers of the 70's and quite frankly, most hams today (when it comes to microwaves).

They would be a great asset to the hobby.

And honestly, you shouldn't feel threatned by them. I doubt if many would be interested in voice or digital on 80 meters, they have a specific goal in mind, and that goal is not ragchewing.

But they are different then you. You'll need to deal with that.

Thanks for the websites - they prove my point! The first one I looked up had disclaimers that say this antenna I am describing is in violation of FCC rules, don't do it, etc., etc., etc. Kinda reminds me of the illegal CB linears sold exclusively to CBers with a big label "Illegal for CB use".
