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 standards were deployed to solve many quality of service (QoS) and security issues related with the previous standards (Banerji, Chowdhury). Figure 1
While IEEE 802.11n covers both of Media Access Control Layer (MAC), and physical Layer (PHY), and the main goal of introducing it was to increase the efficiency of the data throughput on the MAC layer, which will increase in transmission speed (Survival…
