Idle
Software is active. Module is registered to the
GSM/WCDMA/TD-SCDMA/EVDO/LTE network, andthe
module is ready to communicate.

taking
Connection between two subscribers is in progress.
In thiscase, the power consumption depends on
network settings such as DTX off/on, FR/EFR/HR,
hopping sequences, antenna.

-SCDMA/EVDO/LTE)Sta
ndby
Module is ready
forGPRS/EDGE/WCDMA/TD-SCDMA/EVDO/LTE
data transfer, but no data is currently sent or
received. Inthis case, power consumption depends
on network settings and EDGE/HSPA+ /LTE
configuration.
(GPRS/EDGE/WCDMA/TD
-SCDMA/EVDO/LTE)Dat
a transfer
There isGPRS/EDGE/WCDMA/TD-SCDMA/EVDO/LTE
data transfer in progress. In this case, power
consumptionis related to network settings (e.g.
power control level); uplink/downlink data rates
and GPRS configuration (e.g. used multi-slot
settings).
Minimum mode
AT command “AT+CFUN” can be used to set the module
to a minimumfunctionality mode without removing
the power supply. In this mode, the RF
part of the module will not work or the USIM card
will not be accessible, orboth RF part and USIM card
will be closed, and the serial port is still
accessible. The power consumption in this mode is
lower than normal mode.
Flight mode
Use the "AT + CFUN = 7" command or lower FLIGHTMODE
pins, the module can be configured to flight mode
under without removing the power supply condition.
In this case, the RF part does not work, but still
can use the serial port and USB, the power
consumption is lower than normal working mode.
Power off
Through the "AT + CPOF" command or lower PWRKEY pin
can power off L506. At this mode, the module of
internal power supply will be closed, and the
system is stop running also. The UART and USB are
unavailable.
Sleep mode
In sleep mode, the module power consumption to a
minimum, but the module is still able to receive
paging information and SMS.
