Researchers at Stanford University have developed a new technique that will lead to faster wireless networking. Introduced to mobile networking experts at the MobiCom2010, the new technique doubles the data rate of communication networks without the need of additional frequencies.
The new technique relies on three antennas, instead of two found in the latest 801.11n wireless devices and permits full-duplex communications at the same frequency. The doubling of wireless networking speed has been achieved using something similar to noise cancellation found in certain headphones. Because the transmitting device knows what it's disseminating, it can also filter it to make weaker incoming transmissions audible. Consequently, a two-way communication can take place on the same frequency.
Since wireless networking relies on standards controlled by the Institute of Electrical and Electronics Engineers (IEEE), the invention will need to be approved by it. It will also need clearance from the 802.11 working group before being formed into a new standard.
