You're confused on the walls thing. The lower the frequency, the better it
gets through walls.

I guess I don't see how this is much different from the other 900mhz base stations available? WaveLan, Proxim's RangeLan, etc all have small boxes available which plug into an ethernet and can do bridging (yuck), NATing of the wireless hosts onto an ethernet, or even routing. For a lot less than $1900 (Proxim's is around $600 from any number of resellers).

900mhz also has the disadvantage of not being a high enough frequency to get through walls very well. As for long distance applications, a pair of relatively inexpensive unidirectional antennas work pretty well with Proxim's stuff. One of the grad students here mounted an antenna on his roof about a mile from campus with direct line of sight and routinely gets 1mbps.
