802.11n High Speed Wireless LAN – Overview and Latest Status

The emerging IEEE 802.11n WLAN (Wireless LAN) transmission technology based on MIMO (Multiple Inputs/Multiple Outputs) guarantees throughput of at least 100 Mbps but can deliver up to 600 Mbps depending on the complexity of the radio and on the environment. Although today's 802.11 networks can reach data rates of 54Mbps, the actual throughput is typically less than 30 Mbps due to protocol inefficiencies. 802.11n is expected to deliver true 100 Mbps throughput as measured at the MAC SAP (service access point) interface and will, therefore, more than triple the transmission speed of WLANs.
