Well, certainly not Wifi that you could deploy in the US without the FCC getting a bit interested in it ;) There are microwave bridges running in the 5.8ghz range that can run 80-100 km available commercially. However, this requires line of sight, and does not use the 802.11 standard. I just wanted Gabriel to see the maximum anyone had successfully attempted. I believe Gabriel's first post was looking to cover a 450 - 500 km distance, which is unfortunately not possible within 802.11 Does anyone know of any projects using WiMax (802.16) yet to start some distance records with that technology?

A 6 WATT power amplifier feeding a 2.4 meter dish (that's the area of FIVE king sized beds), not to mention a high altitude balloon, helium and all the launch gear, plus GPS tracking systems for the antennas and presumably clearance from government and military authorities to drift around at commercial air-space altitudes in a random direction. I make that an output of nearly 90dBm and a receive sensitivity of probably -140dBm. Allow, say 10dB noise margin and you have a mind blowing 220dB headroom to play with. Compared to a free space loss of 'only' 150dB for the 315Km link and you wonder just how far they COULD have gone. BUT... Can you still call that WI-FI? :-) >FYI > >Alvarion and Breeze set the Guiness world record for the longest WLAN >link at 310 km > >http://www.alvarion.com/RunTime/CorpInf_30130.asp?fuf=298&type=item > > > >[EMAIL PROTECTED] > > [Non-text portions of this message have been removed] ******* Wireless LAN Weblog - WLAN Forum http://www.wireless--lan.com/ Wireless LAN Search http://search.freefind.com/find.html?id=6750665 Wireless LAN Jobs - WLAN Jobs http://groups.yahoo.com/group/wlanjobs/ http://www.azhttp.com/ <a href="http://www.azhttp.com/";> Arizona High Tech Talent Partnership</a> http://www.science-fairs.com/ <a href="http://www.science-fairs.com/";> Science Fairs</a> If you got this from someone else you can join at http://groups.yahoo.com/group/wirelesslan/ or mailto:[EMAIL PROTECTED] To unsubscribe: mailto:[EMAIL PROTECTED] Yahoo!
