My home requires six WiFi access points (AP)for full coverage and "four bar" indication virtually everywhere. To minimize interference among them, I allocate a different channel to each AP, but since there are only three channels available for high speed WiFi in the 2.4 GHz band, some APs would have to use the same channel. WiSpy is the ideal tool to observe, using a laptop PC, the activity at each location, including my own APs and neighbors equipment. It was easy to install and set and with all display options I could develop a feeling of the best channel for each AP, including interference from non WiFi equipment. Now I use it occasionally to troubleshoot coverage issues. For less than $100 it is a great spectrum analyzer.

I needed to monitor the 2.4 GHz WiFi spectrum at a sports venue for potential interference. This device did all that I expected, providing real-time spectrum views as well as several hours of history.

Works well but not as fast as I expected (real time updates are kinda slow, not sure if there is a way to make it faster). The bundled software is pretty good as well but not top notch.

This unit is for 2.4 MHZ only! The desciption at the time said that it would detect 2.4,5.8 and 900 MHZ. I returned it.
