Battery charge, measure

Peak use cases are defined by continuous measuring the fill level and send the values over
LTE interface. This combination of usage is only possible with the LTE / 3G HSUPA operation
with bit rates of 42Mbps or higher.
The 3GPP Modem may reach a transient peak current 1.3 A (average current 1.1 A), when the
module works at LTE/3G mode (the module transmits at the maximum power) and the power
consume may reach for extreme short times a peak value of 8.25W.
5.3 LTE and WCDMA Module Specifications
The 4G (LTE) / 3G (WCDMA) module, further reference as LTE module, supports one RF
connector used for external antenna connection and is used to receive and transmit RF
signals. The LTE module adopts standard LLC module RF connectors and uses U.FL
connector.
There is a second position for placing a U.FL connector, reserved for GPS / GLONASS /
BeiDou. The GPS / GLONASS / BeiDou functionalities are not supported with the current
device.
