FR/EFR/HR, hopping sequences, and antenna.
UMTS/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.
UMTS/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 USIM 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” or pulling down the FLIGHTMODE
pin can be used to set the module to flight mode without removing the
power supply. In this mode, the RF part of the module will not work,
but the serial port and USB port are still accessible. The power
consumption in this mode is lower than normal mode.
Power off
Module will go into power off mode by sending the AT command
“AT+CPOF” or pull down the PWRKEY pin, normally. In this mode
the power management unit shuts down the power supply, and
software is not active. The serial port and USB are is not accessible.
5.3.2
Sleep mode
In sleep mode, the current consumption of module will be reduced to the minimal level, and
module can still receive paging message and SMS.
Several hardware and software conditions must be satisfied together in order to let A7608SA-H
enter into sleep mode:
1.
UART condition
2.
USB condition
3.
Software condition
Note: Before designing, pay attention to how to realize sleeping/waking function and refer to
Document [26] for more details.
5.3.3
Minimum functionality mode and Flight mode
Minimum functionality mode ceases a majority function of module, thus minimizing the power
consumption. This mode is set by the AT command which provides a choice of the functionality
levels.
●
AT+CFUN=0: Minimum functionality
●
AT+CFUN=1: Full functionality (Default)
