5G networks – full duplex wireless technology

Researchers at Rice University announced that they have successfully demonstrated full-duplex wireless technology allowing for a doubling of traffic on the network without changing hardware or build more cellular towers. Full-duplex technology would allow a cell phone or other wireless device to transmit data and receive data on the same frequency. Today’s networks require separate frequencies to send and receive.

Innovative full-duplex technology requires a minimal amount of new hardware for both mobile devices and networks. Full-duplex technology does require new wireless standards, meaning it might not be available for several years as carriers move to 5G – said Ahutosh Sabharwal

MIMO uses multiple antennas and the Rice team was able to send two signals in a way that they cancel each other out, allowing a clear signal to go through over the single frequency.
