The latest IEEE 802.11ax Wi-Fi Standard, named Wi-Fi 6, is known for having several advancements, such as improved performance and efficiency, faster speeds, better coverage, and reduced latency. The multiple access system is Orthogonal Frequency Division Multiple Access (OFDMA) with Multi-User MIMO (MU-MIMO). This work explores a thorough examination of the operation of an OFDMA and MU-MIMO system and how it will function as more users are added. Additionally, it evaluates how well this system performs in comparison to systems that solely employ OFDMA or MU-MIMO.

摘要

The latest IEEE 802.11ax Wi-Fi Standard, named Wi-Fi 6, is known for having several advancements, such as improved performance and efficiency, faster speeds, better coverage, and reduced latency. The multiple access system is Orthogonal Frequency Division Multiple Access (OFDMA) with Multi-User MIMO (MU-MIMO). This work explores a thorough examination of the operation of an OFDMA and MU-MIMO system and how it will function as more users are added. Additionally, it evaluates how well this system performs in comparison to systems that solely employ OFDMA or MU-MIMO.
