7.6.2 Average Power
You may specify your own tolerances for the average power measurement. According to GSM
specifications, the limits depend on the power control level (PCL) used by the mobile for transmission
to the base station (CTS). Tolerances at the highest level are narrower than those at the other levels.
Enter the value for the highest level in the Tolerance 1 field, tolerances for the other PCLs in the
Tolerance 2 field. The lowest power level, which was introduced with GSM phase II, is compared with
the value entered for Tolerance 3. Tolerances specified for GSM900 are listed in the table below:
