Análisis de rendimiento del estándar 802.11ax aplicando OFDMA mediante software de simulación

Abstract

The evolution of WLAN networks have had a significant boom in re-cent years due to the number of users and applications that need to connect to the network, so the IEEE 802.11 working group created the 802.11 ax standard to provide better quality service in low or high density environments by implement-ing new features compared to its predecessor, the 802.11ac standard. This article details the design and performance simulation of the 802.11ax standard by ap-plying OFDMA (Orthogonal Frequency Division Multiple Access) using Matlab simulation software, which aims to analyze the features implemented in the new standard, especially OFDMA that allows multiple users with different band-widths obtain a part of the available spectrum through the Resource Unit (RU) assigning adjacent subcarriers by subdividing the channel for data transmission. Contrary to its predecessor, the 802.11ac standard, which works with OFDM technology that uses the subcarriers of the channel for data transmission, assign-ing it to a single user, thus wasting significant bandwidth. The results show the comparison of performance, packet loss and latency between the 802.11ax stand-ard and the 802.11ac standard by generating data traffic for a single user and multiple users.
