Enabling RF Optimization

By default, RF Radio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. optimization is enabled on APs, and the channel and power transmission settings are static on AP radios. When RF optimization is enabled on APs, the AirMatch service on Aruba Central collects sample data about the RF environment from each AP in a network, and automatically tunes the transmission power and channel allocation on APs in a dynamic way.

To enable RF optimization on APs, complete the following procedure:

  1. In the Aruba Central app, set the filter to Global.
  2. Under Manage, click Devices > Access Points.
  3. Click the Config icon.
  4. To enable RF optimization, turn on the Activate Optimization toggle switch.
  5. To automatically deploy the optimization at a specific time, select the required time from the Automatically deploy optimization at drop-down list.
  6. Select the time at which you want to deploy automatic optimization.
  7. Under Wireless Coverage Tuning, set one of the following wireless coverage tuning options for each radio:
    1. Conservative—Takes no or very few corrective actions for channel and power adjustments. Allows algorithm to prioritize preserving network settings over optimal RF health.
    2. Balanced—Allows you to dynamically adjust radio channels and power while keeping a balance between preserving network settings and finding optimal RF settings. This is the recommended option.
    3. Aggressive—Allows you to prioritize change of radio channels and power, over preserving network settings.

    When you apply the RF optimization changes in a live network, it may impact the clients that are currently connected to the network. Aruba recommends that you exercise caution when applying RF optimization on all APs in the network.
