As 802.11b becomes more and more congested, we're looking at alternatives to use for relay or backhaul links. Price is always an issue, so we're considering 802.11a gear which thanks to 802.11g now seems to be largely ignored in the consumer realm and is thus sometimes quite cheap.

The project pages below describe how we built our own backhaul for approximately $450 using two $22 surplus Proxim Harmony APs, a Soekris board, patch antennas etc.

Important Note About FCC Compliance: We are currently evaluating the FCC compliance of the prototype 802.11a system described here. Anyone seeking to emulate our design should do likewise! We take compliance seriously and will modify the design to comply if at all necessary.
