Channel and Power Settings

Modify Channel and Power settings to fine-tune channel selection within an RF Management policy. Channel and Power settings are available on all APs that are supported by ExtremeCloud IQ Controller.
Note

Note

APs retain the last known channel and power settings after a connection loss or reboot.

Field Description
Channel Width
Represents the desired channel width. The channel width is set for all APs in a device group. Available options include:
  • 20 MHz
  • 40 MHz
  • 80 MHz (supported on 5GHz only 802.11ac and 802.11ax)
  • 160 MHz
    • AP5xx – Radio 1 and Radio 2 support 160 MHz
    • AP4xx / AP4xxC – Radio 2 only (5 GHz band) supports 160 MHz
    • AP4000/ AP4000-1 – Radio 2 (5 GHz band) and Radio 3 (6 GHz band) support 160 MHz
    • AP5010 – Radio 1 (5 GHz band) and Radio 3 (6 GHz band) support 160 MHz.
    • AP5050 – Radio 1 (5 GHz band) and Radio 3 (6 GHz band) support 160 MHz. (Radio 3 is currently turned off for regulatory compliance.)
    • AP3xx/AP3xxC — Do not support 160 MHz width on the 5 GHz radio.

    A best practice is to use a predetermined width configured as part of the design of the entire RF deployment. To learn about how Smart RF handles channel width settings, see Understanding Smart RF and Channel Width.

Best Practice: Operating a 40 MHz channel in a 2.4 GHz band can cause co-channel inference with access points in the vicinity. The 2.4 GHz band has limited available channels. Therefore, for proper channel isolation, a 2.4 GHz band allows 3-4 (region dependent) 20 MHz channels. Best practice is to configure a 40 MHz channel on a 5 GHz radio.
Min TX Power dBm Determines the minimum power level for the radio. Use the lowest supported value in order to not limit the potential Tx power level range that can be used for the radio. The Min Tx Power setting cannot be set higher than the Max Tx Power setting.
Max TX Power dBm Determines the maximum power level that can be used by the radio in dBm. The values are governed by compliance requirements based on the country, radio, and antenna selected, and will vary by AP.
