Tsunami QB-8100 Series (100 Mbps/5 Mbps Models) Installation and Management Guide 38
Frequency Domain It specifies the country of operation, permitted frequency bands
and regulatory rules for that country/domain. Upon choosing 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/domain.
NOTE: Units sold only in the United States are
pre-configured to scan and display the outdoor
frequencies permitted by the FCC. No other country
selections, channels, or frequencies can be configured.
Units sold outside of the United States support the
selection of a Country by the professional installer. If
you change the Frequency Domain, a reboot of the
unit is necessary for the upgrade to take place.
NOTE: On World units, if World 5 GHz is selected from
the Frequency Domain drop-down menu, any Channel
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 information on frequency domains, refer
to Frequency Domains and Channels.
Radio Mode It specifies the mode of operation of the Unit. The device
supports 2 types of modes, End Point A and End Point B,
synonymous to Master/Slave and Base/Satellite. For establishing a
link, configure one device as End Point A and other as
End Point B.
Channel Bandwidth It specifies the channel bandwidth. 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 Selection Enable or disable the auto channel selection for wireless interface.
If ACS is enabled on the End Point A, it scans all the channels and
selects the best channel at the start up. If ACS is enabled on the
End Point B, End Point B continuously scans all the channels till it
connects to an End Point A.
NOTE: ACS is enabled by default on End Point B.
Preferred Channel It displays a list of available channels in the specified frequency
domain. Configure this if you want to operate the device in a
specific channel.
NOTE: When DFS is active, the Device will automatically
pick a new channel when RADAR interference is
detected. Preferred channel is applicable only when
Automatic Channel Selection is disabled.
