5.1.2 Working Current
The working current range of the module is as shown in Table 5-2 to Table 5-4. The tables provide the
working power consumption under LTE and WCMA mode. As the power consumptions are affected by
many factors, it‘s normal that there are some differences when tested by users, and these tables can only
be viewed as one example.
