Heatmapper Charts Your Wi-Fi Signal Strength

By Jason Fitzpatrick on January 18th, 2011

If you’re trying to get a bead on the weak spots in your office or home’s Wi-Fi coverage, free Windows application Heatmapper makes short work of generating a heatmap of signal strength for your location.

By default the application generates the map over a simple grid. To make the app radically more useful you can swap out the grid for a blueprint of the building you’re mapping. If you’ve got a copy to scan that’s great but all you really need is a simple outline of the rooms slapped together in Paint to get the job done.

Fire up the app on a laptop, walking around the area you’re mapping (clicking on the virtual map to take measurements) and when you’re done you’ll have a detailed map of the Wi-Fi strength across your location. Armed with that info you’ll know where you need to tweak your wireless network with the addition of better gear or increased output.

Heatmapper is a free application and requires a basic email signup to download.
