WiFiFoFum is a powerful and free WiFi-Scanner for Windows Mobile.
- shows: encryption, MAC-Address, name of the network, max. signal strength, min. signal strength, channel, first seen, last seen, type (ad-hoc or infrastructure)
- save list as XML to view them on a desktop computer
- notifications on new networks
- aggressive scan mode
- GPS support: logs coordinates to every WiFi-network
- radar view
- scan interval: 100 – 5000 miliseconds
I tested it on Windows Mobile 5 and 6, the program worked fine on both. While the program itself is “free”, the developers of WiFi FoFum would be happy about a donation!
