On a regular walk through the city you pass through many wireless networks. Some of these networks are open and available for anyone to use. As someone on the go, with a mobile lifestyle and a laptop, it could be useful to know when you are in the presence of such networks.

Instead of detecting networks by stumbling over your laptop or relying on warchalking affecionados and wardrivers, WiFisense is a wearable scanner for wireless networks.

WiFisense scans for the presence of WiFi (802.11) networks wherever you go. It detects the networks' signal strength, and whether they are password protected (WEP-enabled) or not.

When WiFisense finds a network, it uses patterns of light and sound to announce its availability, quality and accessibility.
