Study and Analysis of wireless networking 802.11n protocol

Abstract

In 1999 the first standard was published after many years from the first wireless packet transmitted in Hawaii. Laptops contributed to the adoption of IEEE 802.11 as the wireless standards. Since then many amendments were published, each time feeding the need for higher throughput. 802.11a/b/g amendments are the most known wireless protocols, with b and g being the most deployed. IEEE 802.11g with the increased throughput was massively considered the standard of IEEE 802.11 family. But the continuous need for higher throughput directed to the implementation of IEEE 802.11n. The amendment boosted the throughput and range with the technologies introduced in both PHY and MAC layer. Key features are PHY MIMO and MAC frame aggregation with block ACK. With the enhancements the throughput achieved in PHY is up to 600 Mbps and MAC above 100 Mbps. Along with QoS, the IEEE 802.11n amendment will be deployed everywhere.
