3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to in the following
chapters.

operation
GSM / GPRS /
UMTS / HSPA /
LTE IDLE
No data transfer 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.
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]).
