Stanford-developed Transceiver Operates Full Duplex on a Single Channel

Wednesday, March 2nd, 2011

To avoid interference, wireless transceivers can switch between transmit and receive on one frequency (Time Division Duplex (TDD)). Or, they can transmit and receive at the same time on different frequencies (Frequency Division Duplex (FDD)). There’s been a flurry of press reports about a new radio system, developed by Stanford researchers, that can operate full duplex on a single channel; that is,¬†transmitting and receiving at the same time on the same frequency, something not done before.
