Coordination of Multiple Access Points in Wi-Fi 8

The rapid spread of Wi-Fi-enabled devices and the exponential growth in data traffic have demanded advancements in wireless communication standards. IEEE 802.11bn [1] (a.k.a. Wi-Fi 8), an amendment to IEEE Standard 802.11-2020 that is currently being developed after IEEE 802.11be, aims to further enhance performance and efficiency compared to IEEE 802.11be. One of the key features of IEEE 802.11bn is the support for multi-AP deployments, which can dramatically improve network coverage, throughput, and user experience. Multi-AP systems involve the deployment of multiple access points (APs) within a single network, working in a coordinated manner to provide seamless coverage and improved performance. The concept of multi-AP includes several architectural and functional enhancements including coordinated AP operation, enhanced coverage, and seamless roaming.
