You don't need to be within eavesdropping distance to suitably disrupt one. The only other immediate thought I had was that you might like to plot a map of WLAN reach at different times of day within different weather conditions. This would demonstrate that your physical security measures appropriately mitigate your WLAN risks. Kev > Just wanted to thank everyone who answered with ideas.
