Tnx...What I have been looking at is using hi-pwr 2.4 as a backbone for not only serving DX Cluster but even
a BBS and maybe some HTTP stuff...I know that they are shooting 802.11b 10 miles with very low cost equipment.
(under 100bucks a site)...Tie this in with 1200/9600kb end users..and I would have a low cost system with hi-speed trunk. I live in the Mtns of Western NC so point to point links would work well.. but..I would not want the gen-public logging into the trunk...hihi
Tnx for all the replys...

Using Wep is kind of like using CTCS on a 2M repeater ... just an awful lot more tones to pick from. hihi

------------------------------------------------------
The legal difference is that CTSS does not prevent anyone from monitoring the output of the repeater. It only prevents someone from accessing the repeater without the proper CTSS tone.
WEP on the other hand actually encrypts the data content with a key so that nobody can monitor it unless they have the key. The concern is that with the data encrypted, the FCC and others have no way to tell if the transmitted data content is legal or not. The work-around is to make the WEP key publicly available so that anyone who wants to check the content can do so. It still prevents the "average non-ham" from accidentally having his data repeated over the backbone.

Channels 1-6 on your wireless router actually fall within the 2.4GHz ham band, and they are shared with part 15 users. I attended a session on HSMM (high speed multi-media) at 2005 ARRL Great Lakes Division Convention in Toledo, OH. What we were told during the presentation, is that if you are going to operate under part 97 rules, set the router to any channel from 1-6, and place your call sign in the SSID of the router. That handles the identification required.
Under part 97 rules, you may run encryption to keep out unauthorized users. You may also use an external amplifier with up to 150w RF output. You must also ensure that no commercial internet traffic passes through your router while operating under part 97 rules. That means no banner ads, or advertising of any kind. Note that when operating under part 97 rules, you have priority over any traffic operating under part 15 rules.
This is currently being done by several hams in Michigan and Texas. If I can find the hand outs we got during the session I'll get you more information.

One other point to consider: If this is for WiFi, and you access any HTTPS (SSL) server, communications is encrypted and therefore illegal under Part 97.
So if there was any intent to go out on the Internet over this system WEP is the least of your worries - a large part of the (useful) Internet runs over SSL.

I wrote an e-mail to the FCC inquiring about the use of WEP in amateur radio transmissions. The FCC's e-mail response is provided below.
--------------------------------------------------
"You are receiving this email in response to your inquiry to the FCC.
Thank you for contacting the Federal Communications Commission.
Station identification must be at required times and always in the clear (not encrypted). The encryption algorithm used for security protocols Wired Equivalent Protection (WEP) and Wi-Fi Protected Access (WPA) etc., must be a published algorithm.
Wired Equivalent Privacy (WEP) is a standardized encryption technology for authentication and protection of the Part 97 network.
Mixing traffic with another service that shares the same frequency band is not a generally accepted practice except in times of emergency. Therefore it is often necessary for High Speed Multimedia radio (HSMM) radio stations to encrypt their transmissions.
A traffic separation technique that is considered acceptable involves the use of wired equivalent protection (WEP) NOT for encryption, but for authentication. If you use this approach under Part 97 you must publish the WEP key. The WEP is used to avoid the accidental mixing of Part 15 and Part 97 traffic, for authentication and NOT encryption.
For further information concerning this technology, please reference 7-10 Chapter 7 of the ARRL's VHF Digital Handbook at:

I'd say that going over the Internet via amateur radio, except to servers under your own control, would be very risky. You not only have the SSL issue but also the probability of pop-up commercial advertising, etc that could easily get you into trouble.
My understanding is that most of this stuff is being used as backbones for local amateur radio networks rather than to permit people to surf the Internet. The only reason for using WEP is to keep the general public from using the amateur nodes.

It will not be used for internet access...just
as a backbone for DX Spots...for now..
Tnx for all the replys!!
