Esineiden internet - Passivinen Wi-Fi

University of Washington CSE and EE researchers introduce Passive Wi-Fi, a system that can generate Wi-Fi transmissions using 10,000 times less power than conventional methods. With this system, 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.
