[brlug-general] WiSpying

[Edmund Cramp]

Well the WiSpy came in last night and I tried it out with the Microwave - WTF!!!! it's back to tin-foil underwear!  I'd rather expected that the Microwave would emit a single strong frequency at 2.45GHz but in fact it's all over the place with strong peaks throughout the entire ISM band - and this with the WiSpy about 20 feet and one internal wall away from the device.

This suggests that your neighbors' microwave could be putting out a signal at least as strong as their Wi-Fi base station.

WiSpy is a cool tool - http://www.metageek.net/
