Full-duplex wireless is the capability of a transceiver to simultaneously transmit and receive on the same frequency. Long thought to be a theoretical concept due to self-interference; great experimental work out of Rice University (and other places) has showed that full-duplex wireless is feasible in practice. Full-duplex allows relaying to occur near-instantaneously and simultaneous downlink and uplink transmissions, but the selection of routing and users must be done to carefully account for self-interference and other complications. My work in this area has been supported by multiple NSF projects, the Academy of Finland, and Renesas.
