In some cases the maximum transmit power of the SU 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.

4.2.6.2.7.1.1 Transmit Power
In the AU, the Transmit Power parameter defines the fixed transmit power level
and is not part of the ATPC algorithm.
In the SU, 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 losing synchronization with the AU.
The minimum value for the Transmit Power Parameter is -10 dBm (the ATPC may
reduce the actual transmit power of the SU to lower values). The maximum value
of the Transmit Power Parameter depends on several unit properties and
parameters:
 The HW revision of the unit
 The Maximum Allowed Tx Power as defined for the applicable Sub-Band:
» For Sub-Band 1 (10 MHz Bandwidth): 20 dBm.
» For Sub-Band 2 (5 MHz Bandwidth): 17 dBm.
 The Maximum EIRP as defined for the applicable Sub-Band, together with the
value of the Antenna Gain. In certain countries, the Maximum EIRP of some
equipment types cannot exceed a certain value. In these cases, the Transmit
Power cannot exceed the value of (Maximum EIRP - Antenna Gain).
 Maximum Tx Power parameter (in SU only)
