IEEE 802.11n
Overview
The standard IEEE 802.11n is an expansion of the 802.11 standard and was approved in
2009.
Previous standards worked either in the 2.4 GHz frequency band (IEEE 802.11g /b) or in the
5 GHz frequency band (IEEE 802.11a). IEEE 802.11n can operate in both frequency band.
In the IEEE 802.11n standard, there are mechanisms implemented in PHY and MAC layers
that increase the data throughput and improve the wireless coverage.
● MIMO antenna technology
● Maximum ratio combining (MRC)
● Spatial multiplexing
● Channel bonding
● Frame aggregation
● Accelerated guard interval
● Modulation and coding scheme
● Data throughput rates up to 450 Mbps (gross)
This is not possible on all devices.
