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.

) 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.
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 this box 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:

-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 this box to enable automatic adjustment of the receiver
sensitivity.
