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.
