Smart RF is supported in standalone and clustered environments. In standalone environments, the
individual controller or service platform manages the calibration and monitoring phases. In
clustered environments, a single controller or service platform is elected a Smart Scan master and
the remaining cluster members operate as Smart RF clients. In cluster operation, the Smart Scan
master coordinates calibration and configuration and during the monitoring phase receives
information from the Smart RF clients. Smart RF calibration can be triggered manually or continues
at run-time, all the time.
Smart RF is supported on wireless controllers managing Access Points in either standalone or
clustered environments.
Within the Operations node, Smart RF is managed within selected RF Domains, using the Access
Points that comprise the RF Domain and their respective radio and channel configurations as the
basis to conduct Smart RF calibration operations.
Managing Smart RF for an RF Domain
Smart RF
When calibration is initiated, Smart RF instructs adopted radios (within a selected RF Domain) to
beacon on a specific legal channel, using a specific transmit power setting. Smart RF measures the
signal strength of each beacon received from both managed and unmanaged neighboring APs to
define a RF map of the neighboring radio coverage area. Smart RF uses this information to
calculate each managed radio’s RF configuration as well as assign radio roles, channel and power.
Within a well planned RF Domain, any associated radio should be reachable by at least one other
radio. The Smart RF feature records signals received from its neighbors. Access Point to Access
Point distance is recorded in terms of signal attenuation. The information is used during channel
assignment to minimize interference.
To conduct Smart RF calibration for an RF Domain:
1. Select Operations > Smart RF.
2. Expand the System mode in the upper, left-hand, side of the user interface to display the RF
Domains available for Smart RF calibration.
3. Select a RF Domain from amongst those displayed.
The Smart RF screen displays information specific to the devices within the selected RF
Domain using data from the last interactive calibration.
