UW engineers achieve Wi-Fi at 10,000 times lower power

(University of Washington) University of Washington computer scientists and electrical engineers have generated Wi-Fi transmissions using 10,000 times less power than conventional methods. With 'Passive Wi-Fi,'signals can be transmitted at rates up to 11 megabits per second -- rates that are lower than maximum Wi-Fi speeds but are 11 times faster than Bluetooth -- and decoded on any of the billions of devices with Wi-Fi connectivity.
