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. jack Matt M wrote: > Hello all, > > I am interested in buying a booster and just wanted to find out who you all think builds a good system (250mw/500mw/1w/2w power levels). > > Thank you, > > Matt > > > > > _______________________________________________ > Talk mailing list > [email protected] > http://seattlewireless.net/mailman/listinfo/talk > > -- Jack Unger ([email protected]) - President, Ask-Wi.Com, Inc.
