6.6 SMART RF

Wireless Configuration
Self Monitoring At Run Time RF Management (SMART RF) is a Motorola Solutions innovation designed to simplify RF
configurations for new deployments, while (over time) providing on-going deployment optimization radio performance
improvements.
Smart RF can reduce deployment costs by scanning the RF environment to determine the best channel and transmit power
configuration for each managed radio.
Smart RF centralizes the decision process and makes intelligent RF configuration decisions using information obtained from
the RF environment. Smart RF helps reduce ongoing management and maintenance costs through periodic re-calibration of the
network. Re-calibration can be initiated manually or can be automatically scheduled to ensure the RF configuration is optimized
to factor for RF environment changes (such as new sources of interference, or neighboring access points).
NOTE: Unlike an RFS series controller, an access point utilizes a single Smart RF
configuration it can use with other access points of the same model. However, the Smart
RF policy needs to be activated from any one of the Smart RF screens. Numerous Smart
RF policies cannot be defined on behalf of the access point.
Smart RF also provides self-healing functions by monitoring the network in real-time and provides automatic mitigation from
potentially problematic events such as radio interference, coverage holes and radio failures. Smart RF employs self-healing to
enable a WLAN to better maintain wireless client performance and site coverage during dynamic RF environment changes,
which typically require manual reconfiguration to resolve.
Motorola Solutions recommends you keep in mind that if a Smart RF managed radio is operating in WLAN mode on a channel
requiring DFS, it will switch channels if radar is detected.
• If Smart RF is enabled, the radio picks a channel defined in the Smart RF policy.
• If Smart RF is disabled, but a Smart RF policy is mapped, the radio picks a channels specified in the Smart RF policy
• If no SMART RF policy is mapped, the radio selects a random channel
If the radio is a dedicated sensor, it stops termination on that channel if a neighboring Access Point detects radar. The Access
Point attempts to come back to its original channel (statically configured or selected by Smart RF) after the channel evacuation
period has expired.
Change this behavior using a
and prevents the radio from coming back to the original channel, even after the channel evacuation period.
NOTE: RF planning must be performed to ensure overlapping coverage exists at a
deployment site for Smart RF to be a viable network performance tool. Smart RF can only
provide recovery when access points are deployed appropriately. Smart RF is not a
solution, it's a temporary measure. Administrators need to determine the root cause of
RF deterioration and fix it. Smart RF history/events can assist.
CAUTION: The access point's Smart RF feature is not able to detect a voice call in
progress, and will switch to a different channel resulting in voice call reconnections and
communication disruptions.
To define the Smart RF configuration:
1. Select the Configuration
command from the CLI. This keeps the radio on the newly selected channel
