3 Operating Characteristics
3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to throughout the
document.
Table 3: Overview of operating modes
Mode Function
Normal
operation
GSM / GPRS /
UMTS / HSPA /
LTE SLEEP
Power saving set automatically when no call is in progress and the USB
connection is detached.
GSM / GPRS /
UMTS / HSPA /
LTE IDLE
Power saving disabled or an USB connection active, but no data trans-
fer in progress.
GPRS DATA GPRS data transfer in progress. Power consumption depends on net-
work settings (e.g. power control level), uplink / downlink data rates and
GPRS configuration (e.g. used multislot settings).
EGPRS DATA EGPRS data transfer in progress. Power consumption depends on net-
work settings (e.g. power control level), uplink / downlink data rates and
EGPRS configuration (e.g. used multislot settings).
UMTS DATA UMTS data transfer in progress. Power consumption depends on net-
work settings (e.g. TPC Pattern) and data transfer rate.
HSPA DATA HSPA data transfer in progress. Power consumption depends on net-
work settings (e.g. TPC Pattern) and data transfer rate.
LTE DATA LTE data transfer in progress. Power consumption depends on network
settings (e.g. TPC Pattern) and data transfer rate.
Power
Down
Normal shutdown after sending the AT^SMSO command. Software is not active. Interfaces
are not accessible. Operating voltage (connected to BATT+) remains applied. Only a volt-
age regulator is active for powering the RTC, as long as operating voltage applied at BATT+
does not drop below approx. 1.4V.
Airplane
mode
Airplane mode shuts down the radio part of the module, causes the module 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 AT command (see [1]).
