4.2. RF output power
Table 25: The module conducted RF output power
Note: In GPRS 4 slots TX mode, the max output power is reduced by 2.5dB. This design
conforms to the GSM specification as described in section 13.16 of 3GPP TS 51.010-1.
4.3. RF receiving sensitivity
Table 26: The module conducted RF receiving sensitivity
4.4. Operating frequencies

4.5. Recommendation of RF pad welding
If external antenna is connected with RF cable welded on the RF pads, please refer to Figure 45.
Any incorrect welding type may cause poor performance both in transmitting power and receiving
sensitivity.
