Module Power
Off mode
Module will go to Power off mode when the Power_on pin has
been pushed low for 2 Seconds.
Normal operation
Module sleep
Module will automatically go into sleep mode when there is
no interrupt input or other operation.
In this case, the current consumption of module will be
reduced to the minimal level.
GSM IDLE
Software is active. Module has registered to the GSM network,
and the module is ready to send and receive.
GSM mode
GSM TALK
CSD connection is going on between two subscribers. In this
case, the power consumption depends on network settings
such as DTX off/on, FR/EFR/HR, hopping sequences,
antenna.
GPRS IDLE
Module is ready for GPRS data transfer, but no data is
currently sent or received. In this case, power consumption
depends on network settings and GPRS configuration (e.g.
multi-slot settings).
GPRS mode
GPRS DATA
There is GPRS data in transfer (PPP or TCP or UDP). In this
case, power consumption is related with network settings (e.g.
power control level), uplink / downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
EDGE mode
EDGE IDLE
Module is ready for data transfer in EDGE mode, but no data
is currently sent or received. In this case, power consumption
depends on network settings and EDGE configuration
EDGE mode
EDGE DATA
There is data in transfer (PPP or TCP or UDP) in EDGE mode.
In this case, power consumption is related with network
settings (e.g. power control level), uplink / downlink data rates
and EDGE configuration.
WCDMA
IDLE
Module has registered to the WCDMA network, and the
module is ready to send and receive.
WCDMA mode
WCDMA talk
Module is active in WCDMA mode. The power consumption
depends on network settings.
HSPA IDLE
Module is ready for data transfer in HSPA mode, but no data is
currently sent or received. Power consumption depends on
network settings and HSPA configuration
HSPA mode
HSPA DATA
There is data in transfer (PPP or TCP or UDP) in HSPA mode.
In this case, power consumption is related with network
settings (e.g. power control level), uplink / downlink data rates
and HSPA configuration
POWER DOWN
Normal shutdown is by sending the “AT+CPOF” command or using the
POWER_ON pin. The power management ASIC disconnects the power supply
from the base band part of the module, only the power supply for the RTC is
remained. Software is not active. The serial interfaces are not accessible.
Operating voltage (connected to VBAT) remains applied.
Minimum
functionality
Use the “AT+CFUN” command can set the module to a minimum functionality
mode without remove the power supply. In this case, the RF part of the module
