Coordination of Multiple Access Points in Wi-Fi 8

IEEE 802.11bn (a.k.a. Wi-Fi 8) aims to improve wireless network performance by utilizing multiple access points (APs) to enhance coverage, reliability and throughput. While achieving this enhancement, one of the most important design and implementation challenges is the coordination of multiple APs to efficiently use the resources and to minimize the interference to the basic service sets of APs during communication. In this paper, we initially provide an overview of the multi-AP concept within the 802.11bn framework. We then present multi-AP coordination schemes that are under consideration by the IEEE 802.11bn task group.
