Here's a sneak peek at Knsgem 2.
May release a beta this weekend.
Knsgem now provides a signal strength plot of your NS or Kismet logs based on 4 user definable signal classifications.
One might find it useful for identifing coverage problems or locating spoofed macs.
This example shows a plot of a single AP near the mouse pointer.
The dots with spikes represent the signal strength and recording location which can be clicked to reveal the actual signal reading.
