! Transmit Power Control (IF-based units only – SU-A/E, AU-BS
and AU-NI) – Controls the relative gain of the Tx power circuits.
A value of 15 represents the highest transmit power level, which is
the maximum level supported by the specific unit. A lower value
represents a lower transmit power level. The effect of this parameter
on the transmitted power is not linear, since it is affected by the
length (attenuation) of the IF cable.
In SUs, if the ATPC Option is enabled this parameter serves for
setting the initial value to be used by the ATPC algorithm after the
first time of powering-up the unit. It will also be used in the
following cases:
a. If the unit does not succeed to associate with the AU after reset
b. If the unit does not succeed to re-synchronize with the AU after
losing synchronization
c. If the SU is associated with the AU but there are too many
successive dropped frames, indicating that it transmits at a
level that may be too low.
The actual run-time value that is used to control the transmit power
level is determined by the ATPC process.
The allowed range is from 0 to 15.
The default value is 15 (maximum power)
The following table displays the transmitted power output as a
function of the value of the Transmit Power Control parameter and
the attenuation of the IF cable.
NOTE:
For IC&FCC compliance, the AU, SU-I and SU-A units (SU-R is not certified
for HDM) in HDM mode must be configured to ensure that the output power
does not exceed 19 dBm.
