As soon as you pressed the Scan button MeeWiMan shows a list of found Wi-Fi hotspots. The strength of signal is shown in the typical dBm unit - where the strongest wireless network signal is around -10 to -30 dBm.
Everything which is higher than -50dBm gets a green color, confirming that it is a very suitable connection. If the number is lower than -90dBm it's colored red, what means you shouldn't even try to use that wireless network.
MeeWiMan shows further informations by tapping the name of a Wi-Fi signal. Those are service sets SSID, BSID or what kind of security (like WPA or WPA2 which are two security protocols for Wi-Fi connections). In addition you find two shortcuts: Connect (to the chosen signal) and Settings which brings you to N9's wireless connection settings menu.

If you're interested in more features like auto-scanning, have a look at MeeWiManPRO.
