Application ShowScannedStationsStatistics

The code is here.

An AP uses its secondary interface to scan all the channels, and obtains all the frames heard, and their statistics. This information can then be used for different purposes e.g. before running a channel assignment algorithm.

This is done with the auxiliary wireless interface.

The output by the screen is like this (three agents scanning in channel 8):
