Performance Evaluation of the IEEE802.11ax Amendment

Since the introduction of the first IEEE 802.11 standard in 1997, WLANs have continued to dominate the wireless communication market. With each new amendment to the standard, data transmission rates have increased, and coverage has improved. IEEE 802.11ax-based WLANs are a promising technology for meeting the demands of high-throughput applications in dense communication environments. This chapter evaluates the performance of IEEE 802.11ax amendment in terms of throughput, considering the impact of channel bandwidth, modulation and coding scheme (MCS), and guard time interval. The performance evaluation is conducted through both simulation and theoretical calculation. The simulation results demonstrate that IEEE 802.11ax significantly improves throughput compared to previous IEEE 802.11 standards, while the theoretical calculation yields even better throughput values than the simulation, as expeted.
