REPORT FOR INTER-BSS INTERFERENCE AVOIDANCE
In dense environments, OBSSs can still be very close to each other. Spatial reuse attempts to tune sensitivity levels and transmit power in devices to isolate as much as possible the different OBSSs, so that OBSSs do not share the medium in time, but rather reuse the medium, which is a great addition from IEEE 802.11ax. Interference can however still happen, especially at the edge of BSSs where, for example, there are hidden node(s). Spatial reuse might even increase this interference in this scenario. Instead of forcing protection with RTS/CTS every time on the edge of BSSs, which can have a negative impact on the spatial reuse and on area throughput, inter-BSS interference avoidance solutions can be applied.
