Effects of Setting an R*SOP Threshold

R*SOP threshold can be helpful when Aps are sharing the same channel. It defines a second higher threshold where the 802.11CCA threshold would normally prevent an AP from ignoring weak transmissions from a distant and filter them out. The R*SOP threshold also reduces AP cell size and addresses remote clients that do not undergo a clean break as they travel outside the RF coverage. This threshold should not be set too high because it can result in the AP cell sizes becoming much smaller than anticipated. The R*SOP threshold is disabled on all APs in an RF group by default. Therefore, it is usually advisable to leverage the point locally using the RF profile and AP groups.

This characteristic implies that radiosensitivity decreases and receiver cell size becomes smaller with increased WI-FI levels. The distribution of clients in a particular network is adversely affected by the reduction of cell sizes. Rx SOP addresses clients with weak RF links, sticky clients, and client load balancing across access points. It is also essential to optimize network performance at high-density deployments such as stadiums and auditoriums where access points need to optimize the nearest and strongest clients. Additionally, its configurations are supported only in Local, Flex-Connect, Bridge, and Flex+Bridge modes.
