Rather than this being a case of letting Slashdot do all of our research for us, we have already deployed two wireless systems with mixed results. One, a Motorola Canopy system, was extremely expensive but worked very well as long as line of sight was available. Given that we are located in East Texas, the LoS issue, combined with equipment cost, caused us to move to an 802.11b Mesh Network. For this network, we used custom-built APs that consisted of PC Engines WRAP boards, 200 mW radio cards, and Locustworld software, because of it centralized management features. While this setup was much more affordable, we have been plagued with a host of problems. The wireless network will slow down even though there is still plenty of bandwidth left on our backend, traffic that passes through just a couple of hops slows to an even slower pace for no apparent reason, and the APs will hang and/or reboot randomly under high temperature (again this is Texas) and high traffic. All in all, it has been a pain for us and our customers. Is there any Mesh or PtMP equipment that offers good stability, can handle the heat well, offers good network management features, and does so at least a somewhat affordable price? And for clarification, the system does not have to be fully 802.11x. Using a different spectrum for backhauls is something we are really interested in, except for the 900 Mhz spectrum, which is already pretty crowded in our area. Information on a setup that works good in an area with a lot of trees would also be extremely appreciated."
