VCC current consumption in fixed active-mode (power saving disabled)
Power saving configuration is by default disabled, or it can be disabled using the appropriate AT command (see
[2], AT+UPSV command). When power saving is disabled, the module does not
automatically enter idle-mode whenever possible: the module remains in active-mode.
The module processor core is activated during active-mode, and the 26 MHz reference clock frequency is used.
Figure 9 illustrates a typical example of the module current consumption profile when power saving is disabled.
In such case, the module is registered with the network and while active-mode is maintained, the receiver is
periodically activated to monitor the paging channel for paging block reception. Detailed current consumption
values can be found in
