VCC current consumption in fixed active mode (power saving disabled)
Power saving configuration is disabled by default, or it can be disabled using the appropriate AT command (see
the
u-blox AT Commands Manual
[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 10 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 the
LARA-R2 series
