Note that many of the following 802.11 (Wi-Fi) tools could be listed in several categories. However, each tool appears in our list only once, under its primary category. For example, if all you want to do is to find APs, choose a Discovery tool. If you want to find APs AND analyze captured Wi-Fi packets, choose a Wi-Fi Traffic Analyzer. If you want to find APs and monitor Wi-Fi traffic observed by a network of sensors (or APs), choose a WIPS. And so on. If you know of a Wi-Fi tool that should be added to this list, please send me email.
