effect of short temporary changes in link conditions. The weight of history (the
previous value) in the formula used for calculating the average SNR is determined
by a configurable parameter. In addition, the higher the time that has passed
since the last calculation, the lower the impact of history on the calculated
average. If the average SNR is not in the configured target range, the BU transmits
to the RB a power-up or a power-down message. The target is that the RB will be
received at an optimal level, or as high (or low) as possible if the optimal range
cannot be reached because of specific link conditions.
Each time that the RB tries to associate with the BU (following either a reset or
loss of synchronization), it will initiate transmissions using its Transmit Power
parameters. If after a certain time the RB does not succeed to synchronize with
the BU, it will start increasing the transmit power level.
In a BU the maximum supported transmit power is typically used to provide
maximum coverage. However, there may be a need to decrease the transmitted
power level in order to support relatively short links and to minimize the
interference with the operation of neighboring systems, or for compliance with
local regulatory requirements.
In some cases the maximum transmit power of the RB should be limited to ensure
compliance with applicable regulations or for other reasons.
Different power levels may be used for different modulation levels by taking into
account possible HW limitations or regulatory restrictions.

4.2.6.2.8.1.1 Transmit Power
In the BU, the Transmit Power parameter defines the fixed transmit power level
and is not part of the ATPC algorithm.
In the RB, the Transmit Power parameter defines the fixed transmit power level
when the ATPC algorithm is disabled. If the ATPC Option is enabled the value
configured for this parameter serves for setting the initial value to be used by the
ATPC algorithm after either power up or loosing synchronization with the BU.
The minimum value for the Transmit Power Parameter is 10 dBm (the ATPC may
reduce the actual transmit power of the RB to lower values). The maximum value
