Figure 8-1, Figure 8-2, and Figure 8-3 show TX Power and IBAT versus TX power level settings for the CC3220MODS module at modulations of 1 DSSS, 6 OFDM, and 54 OFDM, respectively. For the CC3220MODSF module, the IBAT current has an increase of approximately 10 mA to 15 mA depending on the transmitted rate. The TX power level will remain the same.

In Figure 8-1, the area enclosed in the circle represents a significant reduction in current during transition from TX power level 3 to level 4. In the case of lower range requirements (14-dBm output power), TI recommends using TX power level 4 to reduce the current.
