Generally, power saving depends on the module’s application scenario and may differ from the
above mentioned normal operation. The power saving interval may be shorter than 0.64 sec-
onds or longer than 5.12 seconds.
3.3.3 Power Saving while Attached to LTE Networks
The power saving possibilities while attached to an LTE network depend on the paging timing
cycle of the base station.
During normal LTE operation, i.e., the module is connected to an LTE network, the duration of
a power saving period varies. It may be calculated using the following formula:
t = DRX Cycle Value * 10 ms
DRX cycle value in LTE networks is any of the four values: 32, 64, 128 and 256, thus resulting
in power saving intervals between 0.32 and 2.56 seconds. The DRX cycle value of the base
station is assigned by the LTE network operator.
Now, a paging timing cycle consists of the actual fixed length paging plus a variable length
pause before the next paging.In the pauses between listening to paging messages, the module
resumes power saving, as shown in Figure 30.

The varying pauses explain the different potential for power saving. The longer the pause the
less power is consumed.
Generally, power saving depends on the module’s application scenario and may differ from the
above mentioned normal operation. The power saving interval may be shorter than 0.32 sec-
onds or longer than 2.56 seconds.
