Wireless Boosters?

[Jack Unger]

Matt,

Please review the FCC power limits. The 2.4 GHz maximum equivalent 
isotropic radiated power (EIRP) limits are:

1. For access-point use, 1 watt of transmitter power (+ 30 dBm) into a 6 
dBi gain antenna for an EIRP of + 36 dBm.

2. For point-to-point use (ONLY - not access-point use) in 2.4 GHz under 
the "3:1 Rule", we can exceed + 36 dBm EIRP if we reduce the transmitter 
power output by 1 dBm below + 30 dBm every time we increase the antenna 
gain by + 3 dBi above 6 dBi. Using the 3:1 Rule, we can increase EIRP up 
to about 48 dBm. Doing so probably won't increase noise for other users 
because the extremely sharp (focused) antenna directivity narrows the 
radiated beam down so much that it's less likely to "hit" other wireless 
networks.

Rather than use high (or illegally high) power, it's much wiser to use 
proper system design, antenna height, antenna gain, and antenna 
polarization. Power really won't overcome 99% of perceived link problems.

Ping me offlist if you would like more specific information.
