5.1.2 Tx Power
The following table shows the RF output power of the module.
Table 27: Tx Power
In GPRS 4 slots TX mode, the maximum output power is reduced by 3.0 dB. The design conforms to the
GSM specification as described in Chapter 13.16 of 3GPP TS 51.010-1 .
5.1.3 Rx Sensitivity
The following tables show the conducted RF receiving sensitivity of the module.
