Create a map with all your wifi spots
Juan Pablo Alonzo
The guys from ekahau software have developed an application that allows you to create maps of all your wifi spots in your office or home and check the signal availability of each of them. You just need to download the software (free by the way), import it a map from your office or home (it can be a 3D or a floor plan) and the software will locate the wifi spots and will show you the signal strength of each of them so you can find blank spaces, security issues and much more.
If you want to know more about this application, you can check their site here. There is info about the software, how to use it, the requirements to run it on your pc and much more.
