setting can be made in steps of 250 KHz, and the center frequency setting must allow for
the channel size and not exceed the granted frequency range. For example, when using
a 7 MHz channel, the center frequency must be at least 3.5 MHz inside the band limits.
Important: RF Channel Settings: Operation in the FWA band is subject to license. The radio
frequency selections must be set correctly before the installed system is allowed to transmit.
The installed system must comply with all governing local, regional, and national regulations.
Contact authorities in the country of installation for complete information regarding the licensing
regime and operating restrictions for that regulatory domain.
RF Channel Separation KHz: (*) Select the separation between channels (HD-FDD
radio only) where: UL Channel = DL Channel + Separation.
Tx Output Power dBm: Select the output power level (dBm) of the radio.

* For best AN-100UX wireless link performance, it is recommended to use a
maximum setting of 35 DBm when operating at 64 QAM.
Important: RF Power Settings: Operation in the FWA band is subject to license. The
radio power selections must be set correctly before the installed system is allowed to
transmit. National Interface documents may identify a maximum output power for the
wireless system, expressed in terms of an EIRP level that must not be exceeded. The
installed system must comply with all governing local, regional, and national
regulations. Contact authorities in the country of installation for complete information
regarding the licensing regime and operating restrictions for that regulatory domain.
SS Tx Power Control Enable: Check to allow the base station to automatically adjust
the transmit power level of subscribers. When enabled, the base station continually
monitors the subscribers and adjusts the transmission power to maintain a requested
RSSI value.
Reference RSS: Select the target value for average Received Signal Strength (RSS) for
subscribers. The Reference RSS setting is the target value for average Received Signal
Strength (RSS) for subscribers RF signals received by the base station. This target
value allows automatic adjustment of the subscriber Tx power for optimum performance
with the minimum of RF interference. The suggested default setting values are indicated
in the following table:
Table 28: System - Wireless Channel Reference RSSI
Channel Size
Initial Setting
3.5 MHz
-75 dBm
7.0 MHz
-72 dBm
These are the suggested initial settings; adjustments to this target value must be made
based on the individual RF characteristics of each deployed sector. The RSSI value
(dBm) for each subscriber can be monitored using the base station SS Info screen (Web
interface). Tx power adjustments are based on a number of factors, and differences of
up to 7 dB may be observed between the Reference RSS setting and measured RSSI.
Auto Rx Gain Enable: Check to enable automatic adjustment of the receiver
sensitivity.
