Visually map nearby wifi signals with Ekahau HeatMapper
Wander around your location and click on the map every time you pause to take a reading, and HeatMapper rolls the collected data into a slick, interactive map. Hover over an access point, and the display updates to show its signal strength.
It's a handy way to help optimize your wireless network - or figure out who's AP you should jump on if your own router happens to take an unexpected dirt nap.
Have a Guinness on us, Molly!
