Researchers at Stanford University have shown it's possible to double the data rate of communication networks without the need for additional frequencies, something that could lead to significantly faster wireless networking.
Described by its inventors as "simple and effective," the new technique relies on three antennas, instead of the two found in the latest 801.11n wireless devices. It allows full-duplex communications on the same frequency (that is, simultaneous send and receive), something considered before now to be physically impossible.
