Comparison Between High Throughput and Efficiency of 802.11 Wireless Standards

The High-Efficiency (HE) standard is considered as generation Wi-FI 6, which is an improvement of legacy 802.11 standards. The new Wi-Fi 6 of 802.11ax standard aims to improve throughput and minimize latency. One of the significant applications of 802.11ax standard will be in dense wireless scenarios such as the Industrial Internet of Things (IIoT). How much 802.11ax as HE standard will improve the throughput compared to 802.11n as Hight-Throughput (HT) standard? The aim of this paper is to tackle this question using the NS3 simulator. This performance comparison will be based on throughput parameters such as the modulation and coding scheme (MCS), the Channel Bounding, and the Guard Interval. The comparison is carried out over the two ISM bands of 2,4 and 5 GHz. The results show that the 802.11ax standard can achieve four times throughput higher than the 802.11n over the same simulation conditions.
