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 must be used to
comply with FCC Part 90 regulations.To insure proper operation, TPC values greater than -9dB should be
avoided when operating a 4954-R unit.
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 Only; 5054-R only): Check this box to enable Turbo Mode. Turbo Mode is
supported only in the United States when DFS is not required, and only for the 5054-R. 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.
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 required, the Frequency
Channel list displays only the channels and frequencies allowed for the selected country.
In countries and bands in which DFS is required, Frequency Channel is not configurable. Instead the channel is
auto-selected by the DFS process.
• Multicast Rate: The rate at which data is to be transferred. This drop down box is unavailable when DDRS is
enabled.
The default multicast rate for the unit 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.
Selections for multicast rate are shown in the following table:
