Rice's new technology was able to repurpose MIMO (Multiple Input, Multiple Output) antenna technology, which is already fairly widely used.

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.

Cancellation of signals had been proposed in theory for full duplex networks a while ago, Sabharwal said, but it took time to figure out a way to implement the idea at low cost without sophisticated new hardware.

In addition to full-duplex technology, Rice has created a (WARP) with open source software that provides a space for researches from other organizations to innovate freely and examine full-duplex innovations.

Also, Sabharwal's team has demonstrated it can provide full-duplex in asynchronous mode, which means that one wireless node can start receiving a signal at the same time it is transmitting, instead of waiting to finish the transmission.
