Essay / 802.11n802.11 are just numbers for people outside of the wireless network, but for people interested in wireless technologies, they have significant value. The Institute for Electrical and Electronics Engineers (IEEE) sets certain standards for researching technologies in certain areas. 802 is a standard that addresses local area networks and metropolitan area networks. 802.11 is the standard dealing with wireless LAN implementation. The IEEE introduced 802.11 to improve communication between computers and similar devices. 802.11 mainly deals with different mechanisms used in the physical and MAC layers to ultimately control the data rate, which defines the efficiency of the system. The first one was introduced in 1997 and several modifications were subsequently made to these standards in order to achieve better data throughput through advanced technologies. When new standards were introduced, most of the old standards were incorporated into the new standard. Additionally, a large number of companies manufacture their products based on these standards in order to be able to compete with their competitors. 802.11a and 802.11g were the most popular protocols before the 802.11n revision. 802.11a is a wireless protocol introduced in 1999. This protocol operates in a 5 GHz band and uses the basic orthogonal frequency division multiplexing (OFDM) waveform and achieves a maximum data rate of approximately 54 Mbps. It was one of the most widely used protocols for wireless systems. However, 802.11g operated on the 2.4 GHz band and used the same OFDM waveform as 802.11a. It was revised in 2003 and became public with a maximum possible bit rate of around 54 Mbps. IEEE 802.11n wireless protocol was not just a revision but a revolution...... middle of paper ...... 802.11 n standard like MIMO, OFDM, Channel Bonding and other factors which are changed in 802.11n compared to its previous standards. These reviews also give an idea of how a protocol is implemented and what conditions are involved in achieving maximum throughput using an 802.11n system. Along with these, I came across some interesting publications and websites included in the reference section that give a brief introduction to wireless. communications and the importance of 802.11 protocols when communicating between computers or other devices. These publications clearly describe the features of the 802.11n protocol and also describe different factors involved in achieving a maximum throughput of 600 Mbps. So, I would like to discuss all the above-mentioned topics as part of my investigation report on IEEE 802.11n with the help of the above-mentioned references.
