Tsunami MP.11and MP.11a Installation and Management

ADDITIONAL INTERFACE INFORMATION

Dynamic Frequency Selection (Tsunami MP.11a only)

With Tsunami MP.11a units, Dynamic Frequency Selection (DFS) is enabled automatically based upon the country you select. You can tell DFS is in use because the frequency selection drop-down box on the Interfaces page is grayed out (click the Configure button and the Interfaces tab); it displays only the DFS-selected frequency. You cannot select a preferred frequency or band in which to operate. DFS scans all available frequencies in all available bands to select the operating frequency automatically.

To comply with your country’s regulations, change the DFS selection to specify your country. You can do this by logging into the unit, clicking the Configure button and selecting the System tab. There is a drop-down box labeled “Country” with all available countries from which to select. Choose your country, configure the unit as required, and reboot for the settings to take effect.

Note: Because DFS must scan for radar and interference on multiple channels, you must allow a sufficient amount of time for the units to start up. This is considerably longer than when the unit is not using DFS. Startup time is usually within two to three minutes if no radar is detected. If radar is detected, the unit may reboot multiple times before it becomes fully operational and can take much longer to start. This is expected behavior.

DFS Requirement

Dynamic Frequency Selection (DFS) is required in ETSI countries and is enabled automatically when you select a country with a regulatory domain that requires DFS. DFS is required in ETSI countries for two purposes.

1.Radar avoidance both at startup and while operational. To meet these requirements, the Tsunami MP.11a BSU scans available frequencies at startup for the presence of a radar signal on all available frequencies; it does not use any frequency in which radar signals are detected. Once fully operational on a frequency, the BSU actively monitors the occupied frequency for radar interference. If radar interference is detected, the BSU logs a message and reboots to find a new frequency free of interference.

Understand that radar detection is performed only by the BSU and not by the SU. When an SU is set to a country in which DFS is used, it scans all available channels upon startup looking for a BSU that best matches its connection criteria (such as Base Station System Name, Network Name, and Shared Secret). The SU connects to the BSU automatically on whatever frequency the BSU has selected. Because of this procedure, it is best to set up the BSU and have it fully operational before installing the SU, although this is not required. If a BSU reboots because of radar interference, the SU loses its WORP link and reboots to rescan available frequencies for an active BSU.
