Figure 12: Description of the VCC current consumption profile versus time when power saving is enabled: the module is in idle
mode and periodically wakes up to active mode to monitor the paging channel for paging block reception
1.5.3.3
Current consumption profiles – Fixed active mode (power saving disabled)
Power saving configuration is by default disabled, or it can be disabled using the appropriate AT command (refer
to
[2], AT+UPSV command). When power saving is disabled, the module doesn’t
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.
An example of the current consumption profile of the data module when power saving is disabled is shown in
Figure 13: the module is registered with the network, active-mode is maintained, and the receiver and the DSP
are periodically activated to monitor the paging channel for paging block reception.
