Chanalyzer 6 uses standard USB Wi-Fi NICs to take channel airtime measurements of every Wi-Fi channel. We use the NICs similar to a Wi-Spy going across the spectrum by hopping the adapters across each channel while simultaneously capturing all Wi-Fi traffic. In many ways, this is more useful because it will include MAC addresses of the devices for better tracking. This does limit the data to just Wi-Fi traffic, but with this data the user can see the other networks causing congestion and even track them down. Instead of a waterfall view, Chanalyzer 6 will graph airtime congestion using box and whisker plots to help visually show air time variability over a period of time.
Additionally, spectrum analysis is supported with the WiPry Clarity, a 6 GHz capable spectrum analyzer.
