[TriEmbed] Low Power, Passive WiFi

[Shane Trent]

Hi Gang,

This sounds interesting. It requires modifying the WiFi router to provide a
continuous carrier signal that the passive devices can reflect in modified
form to transmit their information. It claims to use 1/1000th the power of
BLE or ZigBee.  It made MIT's list of 10 Breakthrough Technologies.
