Please tell me, how do I get off this list? I've requested to be removed several times and still I have not been taken off. Please help.

Eventually when I get around to setting up some of these hotspots I will be both courteous and to the "letter." I will also observe the EIRP *before deployment as a kind of assurance and vendor check. It's darn hard deciding on either a packaged solution or home-brew though... I'm getting closer. I just have to convince the real-estate that this is good for them and us. ;-) I read the CWNA book a few months ago and it covered this subject too. I don't think it mentioned the personal use of a homemade antenna but I could be wrong... I'll have to look that up. Your book is on my list. I just signed up with Cisco Press not too long ago to acquire some books on routing topics...

You could observe the "spirit" of the law. The spirit aims to minimize interference so the maximum Equivalent Isotropic Radiated Power (EIRP) for an access point is 4 Watts. There is also the "letter" of the FCC law - to minimize the production, marketing, and mis-use of amplifiers that would make it easy for the public at large to use more than 4 W. EIRP - the FCC says that amplifiers can only be used in systems that have passed through a test lab and been certified to comply with both FCC spectral purity and FCC power requirements. Therefore, if you use an amplifier with a transmitter and antenna system that does NOT exceed 4 W. EIRP, you meet the "spirit" of the law but not the "lettter" of the law - you are still operating illegally. In the real world, many WISPs are in this catagory (either through ignorance of the law or intentionally ignoring the law) where they observe the "spirit" but not the "letter" of the law. Many non-WISP users are either ignorant of the law or just don't care and just use as much power as they want. These are the people who screw up the band for all the rest of us. Amplifier companies (IMHO) vary in their degree of obervance of the FCC regulations. Some are blantant law-breakers - others are very subtle law-breakers. Even the most responsible amplifier companies (I won't mention any names, but one starts with "Y") are (again, this is just my opinion) very sophisticated in their public stance but still bend the law by marketing amplifiers alone (not as a part of a certified system). I could go on (I have strong opinions but hey, when you don't sell equipment, you get to have strong opinions) but I think I've answered your question. Making one Cantenna for your own personal use is not illegal. There is a provision that allows this as long as you don't exceed 4 W.
