w2aew | #253: How to capture & analyze WiFi WLAN signals off-the-air with an RSA | RSA306B 802.11 @w2aew | Uploaded February 2017 | Updated October 2024, 7 hours ago.
PC based video, by request, while I recouperate from my ankle injury.
This video shows how to capture and analyze WiFi (WLAN) signals off the air, and perform some analysis on those signals. OTA (over the air) signal capture and analysis of 2.4GHz ISM band signals presents many challenges including interference, trigger challenges and multi-path interference. However, given these challenges, with care you can achieve reasonable results. I used a Tektronix RSA306B for this video, but the same techniques apply to all USB based RSAs. The benchtop RSA products include additional trigger functionality which greatly improves the ease of triggering specifically on the signals of interest. I show analysis of 802.11g signals, but options allow analysis for other variations of the standard including 802.11b, 802.11a, 802.11n, 802.11j, 802.11ac, 802.11p.
