Imagine if you could use your Pocket PC to sniff-out wi-fi hotspots. No more of that walking around wth your laptop looking for that elusive WiFi. Simply use Sniffi to literally sniff out WiFi spots in your neighborhood or working area. Sniffi is an advanced WiFi networks manager which may be used to search for hotspots, as a connection manager or as a network parameter monitor.
The application works in a very similar way to Windows WiFi network manager. The list of available networks is clearly displayed together with their ID, protection status and signal strength. There's a day/night color profile, fullscreen switch and you can switch it from vertical to horizontal mode easily. You can even perform pings on available networks and view TCP/IP stats for each one.
This is not the most effective WiFi detection system as much will depend on your mobile's capabilities but if you can't be bothered turning on your laptop to see what's available, its better than nothing.
