The IEEE Standards Association has approved WiGig, a very fast, short-range networking technology that operates in the 60-GHz band. WiGig, also known as 802.11ad, has the potential to eliminate the tangled bundle of wires at the back of PCs, and could start appearing in routers as early as the second or third quarter this year. The technology would transfer data at 7 Gbits per seconds, compared to current routers using 802.11g technology that transfer data at 50 Mbits/s and 802.11n at 100 Mbits/s.
The 60-GHz band shortens the range of WiGig to about 40 feet, but it also makes its signal more robust. IEEE says improvements in spectral reuse and beam forming for WiGig now make it possible for users in denser deployment environments to maintain top-speed performance, without interfering with one another or having to share bandwidth. WiGig's transmission speeds also should enable many home networking applications.
The approved version includes a feature called Fast Session Transfer, which enables seamless and quick switching between WiGig and legacy technologies working in the 2.4-GHz and 5-GHz bands.
