Radio Management

The Radio Management page allows you to configure the radio channel on which the AP needs to operate. This reduces interference and helps to optimize the AP radio performance by operating in an optimal RF channel and bandwidth. The radio management configuration is global to a site and can be accessed from the advanced menu in the Inventory page. The APs in the site use only the selected channels and allowed channels for the channel width.

Changing these settings may disconnect clients from the network.

Follow these steps to configure a radio channel on which the AP should operate:

  1. Tap the Inventory tile on the Instant On home page or tap the Site Health banner and select Show inventory
  2. Tap the advanced menu () icon and select Radio management.
  3. If you have an AP32 access point, deployed at the site, select the preferred frequency from the Radio frequencies (AP32 only) dropdown.
    • For AP32 access points, mesh configuration is possible only under the 5 GHz radio. When using AP32 as a mesh point on 5 GHz radio and the user decides to change the radio frequency to either 2,4 GHz + 6 GHz globally or locally, the mesh point will go offline and the user will have to connect it using an Ethernet cable instead of mesh to bring it back online in the site. User can then change back radio frequencies dropdown for AP32 to include 5GHz to re-establish the mesh link.
    • If the user decides to select 2.4 GHz and 6 GHz, a message will be displayed to alert the user that mesh devices might be affected as they are operating under 5 GHz. The user is required to Confirm the action to proceed.
  4. Choose a Channel width for each of the following:
    1. 2.4 GHz Radio—20 MHz (default) or 20/40 MHz.
    2. 5 GHz Radio—20 MHz, 20/40 MHz, 20/40/80 MHz (default), or 20/40/80/160 MHz.
    3. 6 GHz Radio—20/40/80 MHz or 20/40/80/160 MHz (default).
    • The 6 GHz radio spectrum is currently available only on AP32 access points.
    • The channel width of 160 MHz is available as a global setting only after an AP25 or an AP32 access point is added to the inventory for the first time. However, the 20/40/80/160 MHz setting will still be available after all the AP25 and AP32 access points are removed from the inventory.
    • The channel width of 160 MHz is supported only on AP25 access points and on the 6 GHz radio channel for AP32 access points. However, these access points when deployed as mesh points will operate only on 20/40 MHz or 20/40/80 MHz (default).
  5. Based on your selection for each radio, the Channel selection options are refreshed. All channels are enabled by default and are displayed in orange. The disabled channels are displayed in gray.

  6. Configure the Transmit power range for the radios by adjusting the slider between a minimum and maximum value. For example, if the slider is set between Very high and Max, the radio transmits between 30 dBm and maximum power. The available values are:

    Transmit Power Level

    Threshold for 2.4 GHz Radio (in dBm)

    Threshold for 5 GHz Radio (in dBm)

    Low

    6 dBm

    15 dBm

    9 dBm

    18 dBm

     

    12 dBm

    Medium

    15 dBm

    21 dBm

    18 dBm

    High

     

     

    21 dBm

    24 dBm

    24 dBm

    27 dBm

     

    27 dBm

    Very high

    30 dBm

    30 dBm

    Max

    This is the default setting.

    This is the default setting.

    The above values are governed by the DRT regulations for each country. If a country does not support transmit power level above 23 dBM under 5 GHz, the user will be limited by this value coming from the DRT regulatory when using the max TX Power setting.

The changes made in the above procedure are saved automatically.
