Self Monitoring At Run Time RF Management (Smart RF) is an ExtremeWireless WiNG™ innovation
designed to simplify RF configurations for new deployments, while providing on-going optimization as
the RF environment changes over time.
Smart RF can reduce deployment costs by scanning the RF environment to determine the best channel
and transmit power for each Smart RF-managed radio. Smart RF policies are added to device groups to
apply site-specific deployment configurations and self-healing values to groups of access points (APs).
Smart RF distributes the decision process between RF Domain Managers (in a Distributed site) or within
the Extreme Campus Controller (in a Centralized Site). Data is used from the RF environment to make
intelligent RF configuration decisions.
Figure 1: Benefits of Smart RF
Smart RF helps reduce ongoing management and maintenance costs by constantly monitoring the RF
environment for external wireless interference, neighbor wireless interference, non-wireless interference,
and client connectivity. Smart RF then applies various algorithms to arrive at the optimal channel and
power selection for all APs in the network, and constantly reacts to changes in the RF environment.
Smart RF is supported on all 802.11n/ac/ax access points with Extreme Campus Controller.
O-Channel Scanning
Smart RF leverages the O-Channel Scanning (OCS) capabilities built into each ExtremeWireless WiNG
802.11n/ac/ax AP to monitor the RF environment in real-time on both 2.4 GHz and 5 GHz bands. When
Smart RF is enabled, by default, each Smart RF-managed radio will go o-channel for 50 milliseconds
