Those of you inclined towards worrying about eavesdroppers will find the following interesting ... QST Magazine (or was it NASA Tech Briefs?) recently reported that two people successfully achieved connectivity and exchanged files across a span of 85 miles, using COTS technology and antennas optimized for operation in the 2.4 gHz frequency. People operating 802.11b networks in corporate environments, take note - your networks can probably be monitored from anywhere within a few [dozen?] miles of the antenna, depending upon obstructions, and perhaps from over the horizon, as well.
