Basic Configuration
Parameter Description
Frequency Domain This parameter specifies the country of operation, permitted frequency bands and
regulatory rules for that particular country or domain. When you choose a frequency
domain, the Dynamic Frequency Selection (DFS) and Automatic Transmit Power Control
(ATPC) features are enabled automatically if the selected country and band has a
regulatory domain that requires it. The Frequency domain selection pre-selects and
displays only the allowed frequencies for the selected country or domain.
:
• Devices sold only in United States are pre-configured to scan and display only the
outdoor frequencies permitted by the Federal Communications Commission
(FCC). No other countries, channels, or frequencies can be configured. Devices
sold outside United States support the selection of a country by the professional
installer. Any change in the Frequency Domain, requires device reboot.
• If World 5 GHz is selected from the Frequency Domain drop-down menu,
channels only in the 5 GHz range are displayed for manual selection.
For a non US device, the default Frequency Domain selected is World 5GHz. For more
details on frequency domains, refer to Frequency Domains and Channels.
Radio Mode Represents the radio mode of the device. Based on the SKU, the radio mode is set to either
BSU, SU, End Point A or End Point B.
In case of a BSU device, you can toggle between BSU and SU modes. Similarly in case of
End Point A device, you can toggle between End Point A and End Point B. But note that a
change in radio mode will reset wireless and WORP parameters of the device after reboot.
Channel Bandwidth Represents the width of the frequency band that is used to transmit data on the wireless
interface. By default, it is set to 20 MHz. 40 MHz can be selected for higher throughputs
depending on the distance and signal quality. 5 and 10 MHz can be selected for greater
flexibility in spectrum selection.
Auto Channel Enables a device to select the best channel for data transmission on the wireless medium,
Selection (ACS) with less interference. By default, ACS is disabled on a BSU/End Point A and enabled on a
SU/End Point B device. When ACS is enabled on a BSU/End Point A, it scans all the
channels and selects the best channel during the start up. If ACS is enabled on the SU/End
Point B, it continuously scans all the channels till it connects to a BSU or End Point A
respectively.
: Irrespective of the ACS status, the BSU/Endpoint A will automatically select a new
channel upon radar detection.
Preferred Channel Applicable only when the Auto Channel Selection (ACS) is disabled. This parameter
enables you to select a specific channel (in the specified frequency domain) for the device
to operate.
Active Channel Displays the current active channel on which wireless interface is operating. When the
Auto Channel Selection parameter is enabled or when the device moves to a different
channel because of radar detection, this parameter enables you to view the current
operating channel.
