• 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.
• 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. 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: For 4954-R models: to comply with FCC Part 90 regulations when using an external antenna, a TPC value of
-3 dB is required regardless of antenna size, and a larger TPC value may be required to limit the total EIRP to
29dBm or less. For 4954-R models that have an integrated flat-panel antenna, a TPC of -9 dB must be used to
comply with FCC Part 90 regulations.To insure proper operation, the maximum TPC attenuation is -9 db.
The -10 dB and -18 dB selections are not usable.
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.
• Enable Turbo Mode (US Non DFS and All Channel 5 GHz (A5) Only; 5054-R Only): Check this box to enable
Turbo Mode. Turbo Mode is supported on US non DFS and all the channels of 5 GHz. Enabling turbo mode, in its
current implementation, allows the unit 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.
