Configuration Tsunami MP.11 5012/5054-SUI Installation and Management
Interface Parameters
73
• Base Station System Name: The name found on the system page of the BSU to which this SU is connecting. This
parameter can be used as an added security measure, and when there are multiple BSUs in the network and you
want an SU to register with only one when it may actually have adequate signal strength for either. The System Name
field is limited to a length of 32 bytes.
If the Base Station System Name is left blank on the SU, it can register with any BSU with a matching Network Name
and Network Secret.
• Operational Mode: This field indicates the operational mode of the unit, depending upon the specific Tsunami MP.11.
This operational mode cannot be changed as it is based upon a license file.
• Network Name: A Network Name is a name given to a network so that multiple networks can reuse the same
frequency without problems. An SU can only register to its base if it has the same Network Name. The Network Name
is one of the parameters that allow a Subscriber Unit to register on a Base Station. The Base Station System Name
and Frequency Channel also are parameters to guide the SU to the proper BSU on the network, but they provide no
security. Basic security is provided through encryption, as it causes none of the messages to be sent in the clear.
Further security is provided by mutual authentication of the BSU and SU using the Network Secret. The Network
Name can be 2 to 32 characters in length.
• Dynamic Data Rate Selection (DDRS) Status: For the WORP Satellite Mode, DDRS Status is read-only parameter
and its value is based upon the WORP Base to which this SU is associated.
When you enable or disable DDRS on the BSU, the BSU sends an announcement to the SUs and the SUs enable or
disable DDRS automatically.
• Transmit Power Control (TPC): By default, the unit lets you transmit at the maximum output power for the country or
regulatory domain and frequency selected. However, with Transmit Power Control (TPC), you can adjust the output
power of the unit to a lower level in order to reduce interference to neighboring devices or to use a higher gain
antenna without violating the maximum radiated output power allowed for your country/band. Also, some countries/
bands that require DFS also require the transmit power to be set to a 6 dB lower value than the maximum allowed
EIRP when link quality permits. You can see your unit’s current output power for the selected frequency in the event
log.
The event log shows the selected power for all data rates, so you must look up the proper data rate to determine the
actual power level.
NOTE: This feature only lets you decrease your output power; it does not let you increase your output power beyond
the maximum allowed defaults for your frequency and country.
Select one of the following options and click OK at the bottom of the window. Your original output power is adjusted
relative to the value selected. The new setting takes effect immediately without rebooting:
NOTE: 24 Mbps and lower modulation have maximum +16 dBm TX power, 36 Mbps has maximum +13 dBm TX
power, 48 Mbps has maximum +12 dBm TX power, and 54 Mbps has maximum +11 dBm TX power. Because
higher modulation has a lower maximum TX power, the total TPC range is smaller at a higher data rate.
Because the minimum TX power is equal for all data rates, each TPC selection has constant TX power for all
data rates except where the maximum TX power is limited.
• Actual Transmit Power Control: The configured Transmit Power Control setting.
