Fix your WiFi's dead zones with Netspot

Netspot is a WiFi analyzer that helps you choose a position for your WiFi access points that is optimized for the space. The process is a pretty simple one. First you load a floor plan of your space to the program. You then mark your position on the floor plan and let the program collect some data, then change your location, mark your new location on the floor plan and let the app collect more date. Once you do this in all of the critical areas, the program can give a suggestion as to an optimum placement for your access point.
Netspot also looks at other WiFi signals in the area and can suggest proper channels etc...
