Configuring the Subscriber Module

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.
• Enable Turbo Mode (Non-DFS US Only): 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 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 the regulatory domain. Refer to
Country Codes for Subscriber Module 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/band.
For countries in which DFS is required, Frequency Channel is not configurable. Instead the channel is auto-selected
by the DFS process.
If All Channels 5 GHz is selected in the Country drop-down menu on the Configure > System page, any channel in
the 5 GHz range is manually selectable.
• 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, as available) 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 Subscriber unit units is multicast.
This drop down box is unavailable when DDRS is enabled.
The default data rate for the Subscriber 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:
TPC Selection (dB) Maximum TX Power (dBm)
0 (default) 16
-3 13
-6 10
-9 7
-12 4
-15 1
-18 (minimum TPC level) 0
