3 Operating Characteristics
3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to throughout the
document.
Table 4: Overview of operating modes
Mode Function
Normal
operation
GSM /
GPRS / UMTS /
HSPA SLEEP
Power saving set automatically when no call is in progress and the USB
connection is suspended by host or not present and no active commu-
nication via ASC0.
GSM /
GPRS / UMTS /
HSPA IDLE
Power saving disabled or an USB connection not suspended, but no
call in progress.
GSM TALK/
GSM DATA
Connection between two subscribers is in progress. Power consump-
tion depends on the GSM network coverage and several connection
settings (e.g. DTX off/on, FR/EFR/HR, hopping sequences and
antenna connection). The following applies when power is to be mea-
sured in TALK_GSM mode: DTX off, FR and no frequency hopping.
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 TALK/
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.
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
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]).
