Performance Analysis of IEEE802.11ax (Wi-Fi 6) Technology using Multi-user MIMO and Up-Link OFDMA for Dense Environment

Recently, there has been a concerted effort to upgrade the IEEE 802.11 Standard, also known as IEEE802.11ax Wi-Fi 6 technology. It was released due to its high-efficiency wireless local area network (WLAN) technologies for congested or crowded environments such as stadiums, public areas such as railway stations, theatres, and other similar venues. Wi-Fi 6 introduces new features as well as acronym. It is faster than expected, but not in the same sense that Wi-Fi has become a victim of its own popularity. Density refers to concentration, such as several users with wireless devices, and we are surrounded by access points all striving to service more data-hungry this has become our high density reality. The 802.11 families have been modified since 1997, with performance enhancements in three areas: modulation strategy, special streams, and channel bounding technique.Wi-Fi 6's popularity has risen dramatically as a result of its high data rate and OFDMA & MU-MIMO principles. It is currently popular due to its high performance and high data rate capabilities, as well as the fact that it cuts installation and maintenance costs, which were previously signed in Wi-Fi 5. In this study, we compare the performance of IEEE802.11ax Wi-Fi 6 to IEEE802.11ac Wi-Fi 5 in terms of throughput, data rate, modulation techniques, number of users, and other factors. Because of the usage of a new technology known as UL-OFDMA and MU-MIMO, a larger number of users can effectively utilize available bandwidth and use the same channel at the same time.
