Three WARC members have recently established a Mesh Network (Hamnet) on 2.4Ghz using Ubiquiti Nanonstation M2 equipment and Linksys WRT-54 routers. These pieces of wifi equipment operate on WiFi channel 1, but because this is in the amateur 2.4Ghz spectrum we are able to load mesh software developed by amateurs and, if necessary, operate on higher power and with gain antennas. The Nanonstation M2s seem to have good signals over 2Km paths with just 500mW of power, allowing 130Mps traffic. The Linksys devices have a more limited range and lower speeds.
An IRC chat node, webserver, bulletin board and demonstration video application are up and running!
For further information contact James ZL2ET to get yourself connected as a new node. Cost is around $170. You will need a computer!
