1.4.5 Power Consumption
The table below briefly summarizes the various operating modes referred to in the following chapters.
Normal operation
GSM / GPRS SLEEP
Various power save modes set with AT+CFUN command. Software is active
to minimum extent. If the Terminal was registered to the GSM network in
IDLE mode, it is registered and paging with the BTS in SLEEP mode, too.
Power saving can be chosen at different levels: The NON-CYCLIC SLEEP
mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes
AT+CFUN=7 and 9 alternately activate and deactivate the AT interfaces to
allow permanent access to all AT commands.
GSM IDLE
Software is active. Once registered to the GSM network paging with BTS is
carried out. The Terminal is ready to send and receive.
GSM TALK
Connection between two subscribers is in progress. Power consumption
depends on network coverage individual settings, such as DTX off/on,
FR/EFR/HR, hopping sequences, antenna.
GPRS IDLE
Terminal is ready for GPRS data transfer, but no data is currently sent or
received. Power consumption depends on network settings and GPRS
configuration (e.g. multi-slot settings).
GPRS DATA
GPRS data transfer in progress. Power consumption depends on network
settings (e.g. power control level), uplink / downlink data rates, GPRS
configuration (e.g. used multi-slot settings) and reduction of maximum
output power.
ULTRA LOW
POWER MODE
Shutdown after sending the AT^SMSO command. The RTC works continuously, but the software is not
active. Interfaces are not accessible.
Airplane mode
Airplane mode shuts down the radio part, causes the Terminal to log off from the GSM/GPRS network
and disables all AT commands whose execution requires a radio connection. Airplane mode can be
controlled by the AT commands AT^SCFG and AT+CALA: With AT^SCFG= MEopMode/Airplane/OnStart
the Terminal can be configured to enter the Airplane mode each time when switched on or reset. The
parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth between Normal mode
and Airplane mode any time during operation. Setting an alarm time with AT+CALA followed by
AT^SMSO wakes the module up into Airplane mode at the scheduled time.
