Interesting Development in WiFi - Full-Duplex Radio

Researchers Muffle Radio Noise to Make WiFi Breakthrough:

A team of Stanford researchers have come up with "full duplex" radios that can talk and listen at the same time -- a feat that enables communications simultaneity over WiFi networks. Cutting through existing WiFi congestion could double network speeds and capacities, encourage ambitious new projects -- such as citywide WiFi -- and even help prevent plane crashes.

so-called "full duplex" radios that can send and receive signals at the same time. Twice as fast as existing radio devices, the new technology promises less congested, more efficient networks.

The basic premise:

"What if radios could do the same thing our brains do when we listen and talk simultaneously: screen out the sound of our own voice?"
