4.4.2.2 Device Location
The Device Location parameter provides location information for the Base Station
equipment.
The location name consists of up to 255 printable characters.
The default Device Location is a null string (empty).
4.4.2.3 ATPC Parameters
BreezeMAX employs an Automatic Transmit Power Control (ATPC) algorithm to
dynamically adapt the transmit power of each SU so that it is received by the
AU-ODU at an optimal level. The algorithm is managed by the AU and optimal
values are calculated separately for each SU based on the actual level at which it
is received by the AU-ODU. MAP messages transmitted to the SUs include
information on the estimated up/down power level change required to achieve
optimal transmit power level.
The ATPC menu enables viewing/updating the following parameters for all AUs:
4.4.2.3.1 ATPC Enable/Disable
The ATPC Enable/Disable parameter controls whether the ATPC algorithm will be
used to determine current optimal transmit level for each SU served by the Base
Station.
The default is Enable.
4.4.2.3.2 Optimal Uplink RSSI
The Optimal Uplink RSSI sets the target level at which all transmissions should
be received by the AU-ODUs for optimal performance.
The range is -103 to -60 (dBm).
The default is -69 dBm.
4.4.2.4 Cell Parameters
The Cell parameters provide a unique identifier for the Base Station, and they are
common to all AUs in the Base Station. Updated Cell parameters are applied for
each AU after resetting the AU (or after resetting the NPU, which causes reset of
all AUs). The Cell menu enables viewing/updating the following parameters:
NOTE
The ATPC algorithm should always be enabled. The option to disable it is available to support
certain tests. After each reset, the Base Station boots with the ATPC enabled, disregarding its
status before the device was reset.
