Configure an SDR Profile

Before you begin, you must create radio profiles. For more information, see Add a Radio Profile.

Software Defined Radio (SDR) scans the surrounding environment and chooses a channel based on those scans. It can also go to a different radio if it finds no suitable channels on the first radio. For example, if it finds no usable channels on the 2.4 GHz radio, then it will switch to the 5 GHz radio instead (so long as the device is capable of dual 5 GHz radios).

  1. Go to Configure > Common Objects > Policy > SDR Profiles.
  2. Select an existing profile, and then select Edit, or select Add.
  3. Type a Name for the profile.
  4. Optional: Type a Description for the profile.
    Although optional, entering a description is helpful for troubleshooting and for identifying the profile.
  5. Select the radio profiles to be applied.

    This allows the device to switch radios automatically and still know which radio profile to use.

    Note

    Note

    If an AP with a 2.4GHz radio for wifi0 is in use (as opposed to a dual 5GHz radio AP), set the static radio profile (radio profile settings on the device specific settings, separate from the SDR profile) to radio_ng_0. If this default radio profile is not in use within device specific settings, the update will fail and the SDR profile will not work.
  6. Select Enable SDR during initial ACSP (the initial boot up of the device) to enable the AP to choose the best channel it can see for the environment upon start up.
  7. Select Enable SDR to periodically run in the background to set the interval for how often the SDR runs in the background.
    If there is a concern that the AP might switch channels and interrupt too many client connections, set a limit of client devices that can be connected and still enable an SDR scan and change.
    1. Type the Interval to specify the time period between SDR scans.
    2. In the Do not switch when station number exceeds field, enter the number of client devices that can be connected.
  8. Select Enable SDR during a schedule time range to specify the time range.
    SDR profiles can limit the number of client connections to interrupt, and enable the profile to run in the background. If both settings are enabled, make sure both station number counts are the same.
    1. Enter values for the time range.
    2. In the Do not switch when station number exceeds field, enter the number of client devices that can be connected.

      If the station number count is 0, the rule does not apply.

  9. Select SAVE.
