5.3 Operating Mode
5.3.1 Operating Mode Definition
The table below summarizes the various operating modes of SIM7020 product.
Table 28: Operating mode Definition
Mode
Function
Normal operation
LTE Sleep
In this case, the current consumption of module will be reduced to the
minimal level and the module can still receive paging message and
SMS.
LTE Idle
Software is
active. Module is registered to the network, and the module
is ready to communicate.
LTE Standby
Module is ready for data transmission, but no data is currently sent or
received. In this case, power consumption depends on network
settings.
LTE Data
transmission
There is data transmission in progress. In this case, power consumption
is related to network settings (e.g. power control level);
uplink/downlink data rates, etc.
Minimum functionality mode
AT command “AT+CFUN=0” AT+CSCLK=1 can be used to set the
module to a minimum functionality mode without removing the power
supply. In this mode, the RF part of the module will not work and the
SIM card will not be accessible, but the serial port and USB port are
still accessible. The power consumption in
this mode is lower than
normal mode.
Flight mode
AT command “AT+CFUN=4” can be used to set the module to flight
mode
without removing the power supply. In this mode, the RF part of
