High-speed Wi-Fi: 802.11n standard approved

The new standard defines a maximum data transfer rate of 600 Mbps, which is more than ten times higher than the previous ceiling of standard 802.11g. Work on the new standard began in 2002, draft version was released in 2007.

However, the technical maximum and the maximum speed is not the real one and the same - the actual rate may be significantly lower than claimed. Thus, for the 802.11g standard with a theoretical speed of 54 Mbps, the actual rate barely exceeded 20 Mbps.



802.11n specification requires the use of frequency bands 2,4 and 5 GHz. The peculiarity of the new standard include the use of technology MIMO (Multiple Input Multiple Output) - the use of multiple antennas for receiving and sending. In addition, extended frequency range from 20 to 40 MHz.

In the near future is to wait for a sale of devices running on the standard 802.11n. Devices using rough (preliminary) version of the firmware, just get the update.
