2.5.2 Maximum Transmit Power Table (SU and RB
Only)
Each entry in this read-only table includes the following details:
Available Range (dBm) The available Transmit Power range for the applicable modulation
level(s).
The minimum value for the Transmit Power Parameter is -10 dBm
(the ATPC may reduce the actual transmit power of the SU/RB 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.
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/RB only)
Defined Tx Power For AU/BU, this is the fixed transmit power level and is not part of the
ATPC algorithm.
For SU/RB, this is 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/BU.
For each modulation level, the unit will use as transmit power the
minimum between the configured Transmit Power parameter and the
maximum Tx power allowed by the HW and the Country Code for the
specific modulation level.
Current Tx Power (dBm) Applicable only for SU and RB. Displays the current transmit power of
the device. If ATPC is enabled, this value is the same as the Defined
Tx Power for the applicable modulation level(s). If ATPC is enabled,
the transmit power level is controlled by the ATPC mechanism.
Modulation Level The modulation level for which maximum transmit power details are
provided in the following columns.
