uw engineers achieve wi fi at 10,000 times lower power /

With "Passive Wi-Fi," UW computer scientists and electrical engineers enjoy generated Wi-Fi transmissions using 10000 times less power than conventional methods. The system can transmit Wi-Fi signals at rates up to 11 megabits per second -- lower than maximum Wi-Fi speeds but 11 times faster than Bluetooth -- that can be decoded on any of the billions of devices with Wi-Fi connectivity.
