Turbulence across 802.11n
In 2004, the IEEE announced work on a new 802.11 standard called 802.11n, thought to be capable of achieving speeds up to a theoretical 540 Mbit/s. The 802.11n differs from the previous 802.11 standards as it uses Multiple-Input-Multiple-Output. MIMO uses multiple receiver and transmitter antennas that allow increased data throughput, thus achiving the high speeds.
The first routers based on 802.11n specification were commercially made available in the markets on April 14, 2006. Offered by Linksys, D-Link, Netgear and others, these routers can be at best called pre-802.11n routers, with speeds in excess of 300 Mbit/s.
This is where the trouble began. In a seperate test, the Farpaint Group determined that the .11n standard products are over-hyped at the moment and that they fell well short of the standard draft.
