Kiss 33cm (900 MHz) Goodbye?

I just came across something in the MRT magazine online. It is that Purdue University is doing a study for Progeny LMS's proposed use of the 902-928 MHz spectrum for its M-LMS location monitoring service.
What will this mean for Hams and part 15 devices such as wireless phones and routers that currently are found in this spectrum?
Will they change their frequencies; require FCC Certification for higher-powered devices? Obviously they will have high powered satellites or transmitters so that the 900 MHz devices will be able to obtain coordinates similar to GPS devices according to the news report which can be found here.
http://mrtmag.com/briefs/intheworks/spectrum-use-study-121206/
In certain areas of the US such as in the west, hams are very active on 900 MHz. This includes ATV, remote control, links, and Satellite Comms. I'm sure band threats have occurred before and will well into the future.
Is this just a wake up call?

Quite honestly I wouldn't worry about this. The Federal Communications Commission - which is already working hard to make sure that BPL does not interfere with amateur radio and other licensed services - would never allow such a thing to interfere with amateur radio spectrum.

P.S. I heard the FCC is selling bridges...anyone wanna buy a bridge? ;)

There aren't any high-power elements to these systems. No 'GPS' like pieces.
The idea is to be able to track firefighters and so forth inside buildings, with no prior infrastructure.
I am CTO of a firm that designs and manufactures such equipment. We're talking microwatts.
No worries!

Amateur radio has a secondary allocation on the ISM band, and Part 15 has the usual Part 15 requirements, which will be enforced , as they always have, for decades.
The succinct answer to your question is: NO.
The real question is what value do you think truly exists in posing such an alarmist view?
Ham radio WILL lose frequency allocations in the coming decade, because there are plenty of frequencies--such as the 200 MHz allocation at 3300 MHz that we virtually don't use.
And we might even have a re-allocation at 902 Megs, but I doubt it.
There are (soon to be) billions of devices using the 902-928 MHz band and they are hardly going away as far as allocations go.

If you have to ask, you have not "been there" already.
I suggest you hook up a Spectrum Analyzer & look at the band profile. I do it a few times a month, at various locations, for various reasons. The allocation is already slap-full of signals far more potent than a system like this.
I have also found that polarization can be your friend. If you don't understand, please see line #1

As it was said in an earlier post. Hams will lose most if not all of the higher bands over time. This is almost a hardcore fact since the FCC has been enjoying the monetary rewards from selling these freqs to the highest bidder!
I have never understood how the FCC got the power to SELL ANY freq. but have been doing so for some time.
Spectrum and bandwidth have become major comondities
over the past years, and will continue to be worth more and more in the future. Nothing in life is free.
everyone wants to get together and fuss about it, but no one wants to get together and do anything about it.
Same with the rest of our govt! We all make jokes, agree there are major problems, but won't take a stand to do anything about it. And will probably elect another CLINTON into the White House. Go figure.

As time goes by, I become more an more convinced that many hams have no bead nor concern about the PUBLIC interest, only for some sense of ownership of bands they don't really use (such as 3300 MHz). And certainly DON'T own!
I am also more and more convinced that many vocal hams must be communists or communards, who do not value the dollar, do not respect free enterprise, and either live off of or expect entitlements. And whine about their troubled tragic lives. I feel OH SO SORRY for them. Boo Hoo!
You read it right: BOO-HOO!
Frankly, if frequencies WE DON'T USE get sold by the government for BILLIONS OF DOLLARS, and this helps cut down the NATIONAL DEBT, I think only an ape would posit a downside to that.
And if you are living off entitlements be GRATEFUL to the hard working folks like myself who cough up the bucks to keep you in the pink, on ham radio, and on the internet.

"Frankly, if frequencies WE DON'T USE get sold by the government for BILLIONS OF DOLLARS, and this helps cut down the NATIONAL DEBT, I think only an ape would posit a downside to that."
That would be fine--if it was what happens. The truth of the matter is this: The more the government takes in, the more it spends. The national debt hasn't gone down since the FCC started auctions of unused bandspace, it has gone UP. Further, some of the money the feds get from auctioning off the airwaves should go to policing and protecting those airwaves, but it doesn't, not one bit. Instead, it goes to wherever the politicos in charge want it to go--and if you don't believe that is true, you are naive. Want proof? Just look at homeland security--millions upon millions spent, and we're not more secure here at home. Just the opposite--we're more vulnerable than ever--and the debt just keeps on going up and up and up.....

W1YW has it correctly. As the an experimenter in the 33 cm band, and operator of a co-ordinated 900 MHz SSTV beacon, we are secondary users. We're not "loosing" anything here.
If it came to guranteeing the lives of firefighters in my area, I would not hesitate to stop transmission, as I might be required.
Sorry to agree with you again, Chip.

No kidding. Just TRY to get the FCC to do something about any of the HUNDREDS of supposedly compliant devices that pollute the airwaves. Remember, Part 15 also covers incidental radiators like electric fences, aquarium heaters, CATV amplifiers, plasma television sets, computer monitors, light dimmer switches, key telephone systems, surveillance cameras, etc.
If you ever decide to try to get the FCC to enforce Part 15 prepare for a *long* battle.
From personal experience I can tell you that the FCC expects amateur operators to 'enforce' the law. The nasty part about this is that if the FCC ever does get involved it comes down on the person that purchased the device, not the place that sold it or the company that made it. As 'enforcers' we have to hold to the same standard.
Let's say a neighbor unsuspectingly purchases a device that is interfering with amateur radio. We are expected to locate the source, notify the neighbor, figure out a correction and have either the neighbor or the operator bear all the costs to correct a device that was sold as a supposedly Part 15 compliant device. The store and the manufacturer both made their money off it and are in no way expected to pay for the correction.
Obviously the manufacturers are figuring this out as the number of Part 15 non-compliant devices are increasing daily.
The problem would be much easier to address if the FCC would place fines and the cost of location and replacement on the sellers and manufacturers of these devices.
If the FCC decides to put Part 15 in the same category as Part 95 we will be in big trouble. By the same category I mean 'virtually un-enforced'.
Addressing the issue of the 900 MHz band it is certain that the less we use it the better the arguement to let a service that would take it. We now have D-Star that uses the band and hopefully as people see how cool it is there will be more use of it. We need to present a need in order to present a reason for retaining the band.
The location devices for firemen are a great idea. If indeed they only transmit a few microwatts and only when on a working fire or similar, I think we won't see a problem with interference on our end. What about the other side of the coin? Do we really want our broadband digital radios interfering with a firefighter's location device? I sure don't. I wonder what a 50 or 100 watt digital signal would do to the location devices.
Stuff to think about when choosing bands for new devices.

It amazes me people would even consider that they might even be "aware" they may be causing interference to such a device.
For example consider how easily you might hear a few microwatts compared to how easily they can recieve your station? So, isn't it more likely that they will recieve "your" station and you may not even hear their transmissions?
What happens if you are already transmitting a signal and the device is activitated at that same time you are transmitting without any prior notice of this fact?
Will this scenerio have the potential to cause "unintentional" interference, possibly jeopardizing someone's life?
I am not saying anyone would do this intentionally, but I feel that if the devices are going to involve "life or death" then perhaps the band allocation they choose should be strictly dedicated to the device.

At last, a voice of reason!
Why is the design on a license-free band? Perhaps because the "red tape" involved in putting it in a already protected public service band is too onerous?

Hey Chip. Why does the govenment get to sell frequencies, when they don't own them? They regulate them, but they don't own them. That's like saying they will be selling the air we breath. Can't happen.

The FCC doesn't sell frequencies; they *allocate* them based on the size of bribe you are willing to pay. :-)

Should all the peoples of these United States stopped paying their income taxes and according to our Constitution and the Bill of Rights, income taxes would be abolished.
Go back and do some reading and see how powerful the citizens of These United States are if they would be as our forefathers who have given us much authority over our present government, both state and federal.

The Chipster said: "That's nothing compared to the 'entitlements'. They make the defense budget look cost-effective!"
The vast majority of entitlement (e.g., mandated by law) expenditures go to paying the interest on the National Debt. I seem to recall that before Dumb-ya took office, the Treasury Department actually was going to do away with additional 30 year Treasury Bonds due to the prospects for a balanced budget.
Now, just a fleeting memory, thanks to the antics of Dumb-ya the spendthrift.

Alright youse guys. "La-La Land" means Southern California.
Most of you are not from here.
Losing 900 MHz seems very likely because the higher the frequency, the more bandwidth. The more bandwidth, the more data can be transmitted.
Who would want the pokey old HF and MF (maybe even LF) frequencies? We all oughta Go There.
Gotta go cash my entitlement check now. Then I'm gonna buy me a brand new Yaekencom for 900 MHz. Help youse guys out. 73, AE6RO

There is enough to be concerned about in the here and now without borrowing worries from the future.
If you use, enjoy, and appreciate what you have, then when the day comes either for the band(s) to go away or for you to go away from the band(s) SK, then you will have taken it for all its worth.
Happy the radio operator, and happy he alone, who can call the present bands his own. Who within himself can say, "Tommorow let the FCC do its worst, for I have operated today!"

Ummm, beg to differ but it is now 2006. Those paging systems are now licensed outside of 902-928MHz, typically 929-931MHz...
There is also some SCADA systems up on the upper edge of 928MHz but just inside the band, under Part 15, that could easily be mistaken for paging because it is bursts of data used at pumping stations, water tanks, etc. to report levels, interlocks, etc.
Although SCADA resides mainly on UHF (450-460MHz) for range concerns, Part 15 902-928MHz has reduced the impedements to using such systems without a long & drawn out red tape session with the FCC.
Anyone familiar with "EZ-Pass" toll system? Guess what frequency is center of the band for reading these tags in toll booths?

...Ok here ya go:
Turns out the EZ Pass transponders use Manchester encoded on-off keying (EG old fashioned pulsed rf modulation) at 500 kilobits/second on a carrier
frequency of 915 mhz at a power a little under 1 mw (0 dbm).
That ought to be worth a whole case of... um.. CD's

There are 1000's of devices used in the 900Mhz band. There will probably be more as time goes on. Look at the 2.4Ghz band, what doesn't operate there? And when the VHF TV channels go off the air, we will probably lose the 220band freqs. and possibly 6meters! All of those freqs will be available to highest bidder...50-250Mhz! Its coming.....

OK, Chicken Little. And, with 6M, 2M and 1.25M go commercial FM broadcast, AM aircraft, Government (feds, state and local) and marine band. Gosh, I won't even be able to listen to the NOAA weather channels anymore.
And, just where will all of now-digital VHF channels migrate to? Sure, they'll need less spectrum, but for now, the digital content is within each 6MHz allocation. Of course, they'll shrink in needed bandwidth. But not go away. Sheesh.
There might actually be an opportunity for us to try to capture some of what was channel 2's allocation for widebandwidth experimentation. You know, ARRLink, using a gazillion digital carriers for that broadband wet dream that ARRL has......

Not being Chicken Little, Certainly not in a panic, as other on here seem to be. Just a fact and figured it would give them something else to worry about. There are NO digital VHF stations, and the bandwidth is not de-creasing...All the new HD Digital channels are on UHF frequencies, with about 5 times the bandwidth they had on VHF. At some point in time the old VHF transmitters will be shut down. They keep moving the exact date, and the frequencies that made up the 2 thru 13 channels will be sold to the highest bidder.
Nope...I'm not Chicken Little, and couldn't give a DAMN one way or the other. I will play radio until they come tell me I can't. My posts were meant to be sarcastic in response to all the "moaning of losing this, changing that, what am I gonna do now", posts that keep popping up.
You know, there is one good thing about change...that is the more it changes, the less it changes, because change becomes the normal.
Gonna go play radio now, fire up my crutch, as its called in another post on here and have some fun.

I don't know what your post is all about, but my input was about amateur radio. What do you want to do, worry about some possibility in the future or operate in the here and now? Now you're worried about the youth? Give me a break! The best thing for young and waivering minds is the University of Hard Knocks. Yes, and I am an authority on that subject. I have thirteen children and three grandchildren so far and growing. Send them to the University of Hard Knocks. Let them struggle to learn Morse Code, too! Nothing of value is obtained without struggle, and once you got the thing, use it! Forget about worrying about the future, because you are only going to get it one day at a time. Do at least one QSO a day, kiss anxiety about 33cm goodbye!

I'm speaking of ham radio as well as everything else. Living one day at a time is fine--but worry about the future too. After all, what kind of world--and ham radio bands--are you leaving to the future generations?
I seriously hope you are not condoning leaving your messes for your kids and grandkids to clean up, are you??

Some folks just can't get it. When you have self-discipline and you teach your children self-discipline, you don't worry about the future - you make your future.
There is no threat to 33 cm!
The only mess I help to clean up is the messed up minds of people who have nothing better to do than wallow in anxiety. The people who make good things happen don't waste time trying to legislate protection for self-esteem starved youths. Good radio operators don't waste their time with sociology textbooks.

"Not being Chicken Little, Certainly not in a panic, as other on here seem to be. Just a fact and figured it would give them something else to worry about. There are NO digital VHF stations, and the bandwidth is not de-creasing...All the new HD Digital channels are on UHF frequencies, with about 5 times the bandwidth they had on VHF. At some point in time the old VHF transmitters will be shut down. They keep moving the exact date, and the frequencies that made up the 2 thru 13 channels will be sold to the highest bidder."
Nearly everything about this statement is false or misleading. Digital stations are currently found on channels 2-69. Post transition in February of 2009, digital stations will be found on channels 2-51. The post transition channel plan has been nearly finalized, and the most heavily used channels will be 7-13. There is no doubt that digital stations will be on High VHF channels There will be very few on Low VHF 2-6, but that is primarily due to the affect of impulse noise on the 8VSB transmissions at those frequencies.
And there is no increase in bandwidth, unless your talking exclusively about information/channel and not frequency spectrum/channel. All digital stations are still in 6 Mhz channels. They might have 5 times the information, but not 5 times the frequency spectrum. And they will still have 5 times the information on VHF as well.

"Frankly, if frequencies WE DON'T USE get sold by the government for BILLIONS OF DOLLARS, and this helps cut down the NATIONAL DEBT,..."
Tell me another fairy tale! Any proceeds from such a sale will undoubtedly wind up in some bureaucrat's(Comissioner's?) pocket and/or in some politician's (or his cronie's) pet project. I'm absolutely certain that the liklihood of the average citizen ever seeing the benefits of such a sale, makes an electron seem gigantic by comparison! And, by the way, 900Mc is abundantly used here in the greater Cleveland area as well.

"Should all the peoples of these United States stopped paying their income taxes and according to our Constitution and the Bill of Rights, income taxes would be abolished.
Go back and do some reading and see how powerful the citizens of These United States are if they would be as our forefathers who have given us much authority over our present government, both state and federal."
OH LORD!!! This makes the FIRST fairy tale almost bearable! I think I'm going to go out to the BBQ and burn some dollar bills before the government does it for me!

Now what is really funny is that the Part 15 Broadband users are evidently "quaking in their booties".
Check this article:
http://www.shorecliffcommunications.com/magazine/volume.asp?vol=31&story=303
But don't lose an sleep over this!
Just get on the bands and get off eham.net
With spectrum it is "Use it or lose it"

Hard to imagine banning Part 15 devices from 900 MHz or anywhere else.
Article is four years old so I guess Part 15 users are safe. Nor did it mention hams as licensed users.
So how did it turn out? AE6RO John

Frankly, I'll be laughing if the West Coast ATV bucnh and the rest of those snobs at SCRRBA get QRMed. They put their own little private band plan together behind closed doors, and refused to hear from Kenwood and the rest of us proposing to allocate channel spacing in the 902 - 906 portion for affordable trunked FM voice systems proposed or already available to the ham market. [For info, research the Japanese PRCS technology used in rigs like the Kenwood TM-3530].
So we had to go on without them. Our systems are designed to avoid QRM by automatically moving to clear channels, so we are the least vulnerable users in shared-use bands like 39cm. I'm yawning over here.

I want to thank W6TH, W6EM, KD5DPE, KX8N, KA2LIM, KE7HLR, K2WH and any others I missed, for their responses to that nut job who has no problem with government selling a public resource it doesn't own. What does he mean, "WE" don't own it? We ARE the public. THEY are public SERVANTS. Or at least that's how it used to be, before flakes from One-Land began squandering our heritage. Don't insult us with your "national" debt. WE didn't mismanage the treasury. It's the FEDERAL debt, pal. It's the most FEDERAL thing we've got. And you helping to bail them out of it only ensures it will get worse.

Yes, there is one that I'm aware of. A Motorola GTX. Be careful, though, there are both 800 and 900 versions. The 900 version is ready to go. The only hangup is that one trunking personality needs to remain programmed.
It uses the same accessories as the GP300 series HTs. Batteries, chargers, adaptors, etc.
More info a www.batlabs.com under models.

This is all very interesting. Has anyone looked at what UHF RFID systems at 36 dBm EIRP can do. They strobe the entire ISM band on 50 chanels 902-928 MHz. Pretty mych looks like a jammer. Not much of a problem if it is a single reader. However in a distribution or shipping warehouse there can be 3-4 readers per door.

WOHA!
Excuse me but what in the world are you saying?
SELL OUT HAM SPECTRUM FOR THE OLD MIGHTY DOLLAR?
Sir that makes no sense at all, pay down the National Debt with spectrum sell off's. So far that has done nothing to solve our Debt but to re-allocate spectrum to private companies who make BILLIONS off the Public whom the airwaves belong to anyways, NO THANKS!
I recommend you step back away from the Corporate GREED and take another look at why Amateur Radio exists, re-evaluate your loyalties, remember how we got to where we are in the overall communications industry.
The first steps were taken by Radio Amateurs who experimented with new technologies and radio spectrum. Sure the Dick Bash book took a lot of wind out of those sails but experimentation is not dead. Selling off our radio spectrum will do nothing to foster new technologies and experimentation for and by Radio Amateurs which then can be applied to the Public Good. If you sell off our valuable and irreplaceable spectrum just to satisfy the Corporate Greed for spectrum. Oh yea, UPS really did a lot with the 220-222 MHz Spectrum they crow bared from Amateur Radio, listen to it lately? Not much traffic, perhaps we should petition the FCC to re-allocate or allow sharing on that spectrum.
I urge CAUTION when suggesting selling off more spectrum to feed Corporate Greed under the guise of helping solve our National Debt. Instead, lets discontinue the propping up of "ARTS" or funding all these pork barrel projects just to satisfy some Congressman’s debt to a campaign supporter. How about reducing the amount of printing our Nation has to do by meeting the requirements of "other languages" We speak English in the United States, right?
I say enough is enough, we keep and USE the spectrum we currently have, take the time to pass on what you've learned thought Amateur Radio, and encourage those Ham’s who've been away from the radio to get on and re-discover why they got a license in the first place, it's a lot of fun!
73's OM.

No the Weather folks were smart, they have become the Homeland Security’s National Emergency Broadcast System for delivering Alerts and Warnings to the Public. With Broadcasters being fed up with the EBS/EAS issues, National Weather Radio has stepped up to the plate and volunteered to take on that role. So no the answer is, NOAA radio will still be there, not sure about the rest of us…
