nication via ASC0.
UMTS / HSPA /
LTE IDLE
Power saving disabled or an USB connection not suspended, but no
call in progress.
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 power down command. Only a voltage regulator is
active for powering the RTC. Software is not active. Interfaces are not accessible. Operat-
ing voltage remains applied.

Airplane mode shuts down the radio part of the module, causes the module to log off from
the network and disables all AT commands whose execution requires a radio connection.
Airplane mode can be controlled by AT command (see
[1]).
