VCC and 3.3Vaux current consumption in connected-mode
During a LTE connection, the module can transmit and receive continuously due to LTE radio access technology.
The current consumption is strictly dependent on the transmitted RF output power, which is always regulated by
network commands. These power control commands are logically divided into a slot of 0.5 ms (time length of
one Resource Block), thus the rate of power change can reach a maximum rate of 2 kHz.
Figure 4 shows an example of the module current consumption profile versus time in LTE connected-mode.
