• Operational Mode (not configurable): This field indicates the operational mode of the unit – 11a, 11b, or 11g –
depending upon the specific Tsunami MP.11. This operational mode cannot be changed as it is based upon a license
file. For the 5012-SUR, this field shows 11a.
• Dynamic Data Rate Selection (DDRS) Status: For the WORP Satellite Mode, DDRS Status is a 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 5012-SUR 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. Also, most countries in
the ETSI regulatory domain 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:
• Enable Turbo Mode: Check this box to enable Turbo Mode. Turbo Mode is supported only in the United States.
Enabling turbo mode, in its current implementation, allows the 5012-SUR to use two adjacent frequency channels to
transmit and receive a signal. By enabling turbo mode, the receive sensitivity improves by 4 dB for the 36 Mbps data
rate and by 2 dB for the 24 Mbps data rate.
NOTE: The additional sensitivity is provided with the impact of using twice as much spectrum and thus increasing the
opportunity of interference and decreased ability for system collocation. Generally, Turbo mode is not
recommended except when the extra sensitivity is absolutely required.
• Frequency Channel: The frequency channel indicates the band center frequency the unit uses for communicating
with peers. This frequency channel can be set in several ranges, depending upon regulatory domain. Refer to Country
Codes and Channels for channelization information.
For countries in which DFS is not enabled, the Frequency Channel list displays only the channels and frequencies
allowed for the selected country.
• Scanning Across Bandwidth: Enable this field if you want the SU to scan across the whole range of channel
bandwidths (5, 10, or 20 MHz) with or without roaming enabled. Disable this field if you wish the SU to scan only
across its configured channel bandwidth.
• Multicast Rate: The rate at which data is to be transferred. All RF traffic between 5012-SUR units is multicast. This
drop down box is unavailable when DDRS is enabled.
The default data rate for the 5012-SUR is 36 Mbps. The SU must never be set to a lower data rate than the BSU
because timeouts will occur at the BSU and communication will fail.
