For the module’s output power, the following should be noted:
At GSM900 and GSM850 band, the module is a class 4 device, so the module’s output power should not exceed
33dBm, and at the maximum power level, the output power tolerance should not exceed +/-2dB under normal
condition and +/-2.5dB under extreme condition.
At DCS1800 and PCS1900 band, the module is a class 1 device, so the module’s output power should not exceed
30dBm, and at the maximum power level, the output power tolerance should not exceed +/-2dB under normal
condition and +/-2.5dB under extreme condition.
