Xirrus Wi-Fi Inspector
This is another excellent program that sniffs out Wi-Fi networks and shares pertinent information about them, such as how close or far away they are. Xirrus Wi-Fi Inspector shows any nearby hot spots on a radar-like display. A separate pane offers detailed information about every hot spot it finds, including signal strength, the kind of network (802.11n, for example), the router vendor, the channel on which the network transmits and whether it's an access point or an ad hoc network.However, if you want more detailed information, including the relative signal strengths of all nearby wireless networks, InSSIDer is a better bet.
