Under Basic Configuration screen, you can configure and view the following parameters.
Parameter Descriptions
Channel Bandwidth By default, the channel bandwidth 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.
: A change in Channel Bandwidth will reset the Tx Rate and Maximum EIRP to
default.
Channel Offset
: Applicable only to Tsunami® MP-8160-BSU; Tsunami® MP-8160-SUA;
Tsunami® MP-8150-CPE; Tsunami® MP-8160-CPE; Tsunami®
QB-8150-EPR-12/50 devices.
The Channel Offset parameter helps to change the operating channel center frequency. If the
predefined center frequencies are not desirable, user can shift the center frequency to suit the
requirements by configuring the Channel Offset. By default, the Channel Offset is set to 0. You
can configure the Channel Offset in the range -2 to +2 MHz.
For example, consider a channel number 100 with center channel frequency set to 5500 MHz.
If the Channel Offset is set to 0 MHz, the center channel frequency remains at 5500 MHz. If you
configure the Channel Offset to 2MHz then the center channel frequency will change to
5502MHz. Similarly for a Channel Offset of -2MHz, the center channel
frequency is changed to 5498 MHz.
: Even though the center channel frequency is changed, the channel number still
remains same, in this case 100.
Auto Channel Auto Channel Selection (ACS) enables the device to determine the best channel for
Selection (ACS) wireless data transmission with less interference.
If ACS is enabled on the BSU/End Point A, it scans all the channels and selects the best
channel at the startup. If ACS is enabled on the SU/End Point B, it continuously scans all the
channels till it finds a suitable BSU/End Point A and connects to it. By default, ACS is
disabled on BSU/End Point A and enabled on SU/End Point B.
: On BSU/End Point A, ACS is performed only during startup.
Preferred Channel Allows the user to select and operate in the preferred channel.
Preferred channel can be configured only when ACS is disabled. If Dynamic Frequency
Selection (DFS) is active, the device will automatically pick a new channel when radar
interference is detected.
