Dynamic Radio Management

When you modify the radio properties of an AP, the Dynamic Radio Management (DRM) features enable you to find the optimum radio configuration for your APs. DRM is enabled by default. The DRM:
  • Adjusts transmit power levels to balance coverage between APs assigned to the same RF domain and operating on the same channel.
  • Scans and coordinates with other APs to select an optimal operating channel.
The DRM feature consists of three functions:

Smart RF

Self Monitoring at Run Time RF Management (Smart RF) simplifies radio frequency (RF) configuration. Smart RF also provides ongoing optimization of radio performance by allowing the APs to dynamically respond to changing RF conditions in real-time.

Smart RF is configured on a per site basis.

To configure a Smart RF policy, navigate to Configure > Sites > RF Management.

Dynamic Channel Selection (DCS)

DCS allows a Wireless AP to monitor traffic and noise levels on the channel on which the AP is currently operating. DCS can operate in two modes: Monitor and Active. DCS is not configurable. By default, Radio 1 is set to Monitor, and Radio 2 is set to Active.
Monitor When DCS is enabled in monitor mode and traffic or noise levels exceed the configured DCS thresholds, an alarm is triggered and an information log is generated. The DCS monitor alarm is used for evaluating the RF environment of your deployed APs.
Active When DCS is enabled in active mode and traffic or noise levels exceed the configured DCS thresholds, the AP ceases operating on the current channel and uses ACS to find another channel to operate on. DCS does not trigger channel changes on neighboring APs.

Auto Tx Power Control (ATPC)

When enabled, ATPC provides your LAN with a stable RF environment by automatically adapting transmission power signals according to the coverage provided by the APs. When you disable ATPC, you are given the option of automatically adjusting the Max Tx Power setting to match the Current Tx Power Level.

ATPC is configured at the device level. To configure ATPC, select Devices > Access Points. Then select a device from the AP list, and select Configure Device. Under each radio, select Advanced.
