NetSpot - wireless survey and conflict solver

For best analysis of wireless dead spots in an area, say a home or office, it is better to give NetSpot an outline illustration of the area needing coverage. After NetSpot analyses signal strength from each checked access point, you will be presented with a map of the area, showing where signals are strongest and weakest, according to colour (green for strong and blue for weak). To solve the problem, transmitting devices can be relocated, or their antennae moved. Run the analysis again to check for improvements.

In addition, NetSpot also identifies each available device by vendor name and SSID, as well as the channel, type, and band used by each device, signal strength, and security setting. This knowledge, along with the signal survey map, is extremely useful for preventing channel interference and signal leakage to unauthorized, nearby devices. By checking off the box for several of the stronger nearby access points (even if they are not yours), you can view various details, including graphs of overlapping channels.

Since NetSpot was originally coded for Macs, an OSX version is also available. The Free version has limitations, yet is still quite useful.
