Wireless communications has changed people’s lives over the years. It’s become a fundamental of existence in each home, enterprise, or public spaces such as hospital, educational organization, airport and hotel. The demand of wireless technology drives people to go in depth to understand the fundamentals of wireless and how to improve it to get faster and securer communication.
IEEE 802.11, the standard of the wireless communication technology developed by the Institute of Electrical and Electronics Engineers (IEEE) for wireless local area networks (WLANs) between a user and access point (AP), or between two wireless devices. (Intel). It first started by developing a connection between home and the office for local area connection, which give a maximum data rate of 2Mbps per AP which increased to 11 Mbps per AP and known as IEEE 802.11b. After that a newer updated versions came up known as IEEE 802.11g and IEEE 802.11a to provide maximum data rate of 54 Mbps. Furthermore, IEEE 802.11n was a newer version came up after 802.11 a/g to give a data rate up to 600 Mbps. These

First, it gives the user the ability to upgrade or downgrade to 802.11 b/a/g network and both of them can exist in the network simultaneously. Secondly, while 802.11n has multiple transmitters and receivers that would heighten the radio frequency (RF) and get a much better QoS performance. Third, it uses Modulation and Coding Scheme (MCS) to for higher speed for data throughput up to 300 Mbps. Fourth, user does not have to implement multiple access points (AP) and would have a high data range because of the improvement in the protocols and the use of multiple radios. Finally, it has a good functionality for large size files such as voice and videos as a reason of having multiple copies of single transmission, which helps the DSP in the receiver to differentiate between spatial stream.
