Initial Blurb: <<  Columbia engineering researchers create what many believe to be a game changing technology

Columbia Engineering researchers have invented and demonstrated full-duplex radio integrated circuits — they are capable of implementation in nanoscale CMOS and allow for the simultaneous transmission and reception of data at the same frequency in a wireless radio.

"This is a game-changer," says Electrical Engineering Associate Professor Harish Krishnaswamy. "By leveraging our new technology, networks can effectively double the frequency spectrum resources available for devices like smartphones and tablets." >>
