true, these are issues I take for granted............. maybe I need to add the disclaimer about reading FCC Part 15............etc, etc, etc. However, depending on your application, there are several legal ways to increase you effectiveness. Again, before you attempt this, read the legalease........
The ultimate way to increase the effectiveness of any radio system is to be able to sweep the area in question to determine if there is any other transmitters in the area that could affect the signal. The 2.4Ghz band that most wireless access devices use is also popluated by cordless phones (home not cellular/PCS), A/V transmitters (like the Wavecom Jr's), Other 802.11 devices, some amature radio, and the ever popular Microwave oven (while not on the same frequency, can wreak localized havoc). Like anything, a good site plan and research is your best friend when thinking about shooting wireless. Height also helps. I have noticed that most of the 802.11 over distance sites out there talk about shooting it up to mountain tops, especially some of the amature radio stuff, for repeating to another area. kw On Tuesday 18 December 2001 15:55, you wrote: > There are FCC issues even without adding external amplifiers.
