Understanding the Key Features of Wi-Fi 6 and Exploring the Effect of Modulation Scheme on Throughput Rate

Abstract

Today, the number of smart devices and applications are increasing day by day, whereas the older versions of Wi-Fi stander, i.e., n/a/g cannot meet the greed and need of these devices. Thus, the development of applications and devices has called to design of a new Wi-Fi version. Hence, a new Wi-Fi 6 vision has been promoted based on 802.11 IEEE stander. The scope of this paper has focused on the study and overview of Wi-Fi 6 features. As well as, exploring the simulation tools that can be used to implement 802.11ax. A simulation has been done by using NS-3 to measure the effect of modulation and coding schemes on the throughput rate. Where a scenario of the network model was taken on a single AP with a node and the MCS value range is (0 to 7), the channel width (20, 40, 80 or 160 MHz) and the guard interval (800ns, 1600ns or 3200ns). The time of simulation was set to 10 seconds. Hence, the output results explained that the change of modulation properties can increase/reduce the throughput rate.
