Power class GSM 900 maximum peak power 0 W ( dbm) 8 W (9 dbm) W (7 dbm) W ( dbm) 0,8 W (9 dbm) DCS 800 maximum peak power W (0 dbm) 0, W ( dbm) Tolerance (db) for condotions Normal Extreme ± ±, ± ±, ± ±, ± ±, ± ±, Note : The lowest power control level for all classes of GSM 900 MS is Lowest power control level DCS 800 only 0 See note The different power steps needed for adaptive power control (see GSM 0.08) shall have the nominal peak power levels as defined in the table below, starting from the lowest power control level up to the maximum level power corresponding to the class of the particular mobile station. Whenever a power control level corresponds to the power class of the MS, the tolerance of ± or, db (see above) shall apply. GSM 900 DCS 800 Power control level Peak power (dbm) Tolerance for conditions Normal Extreme ± ±, Power control level Peak power (dbm) Tolerance for conditions Normal Extreme ± ±, ± ± ± ± ± ± ± ± ± ± Furthanmore the peak power actually transmitted by the MS at each of the power control steps shall form a monotonic sequence, and the interval between power steps shall be ±, db. A change from any power control level to any power control level may be required by the base transmitter. The maximum time to execute this change is specified in GSM 0.08
