3.4. Operating Modes

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

Table 5: Overview of Operating Modes

Mode

Details

Normal Operation

GSM Idle

Software is active. The module has registered to the GSM network

and is ready to send and receive data.

GSM Talk/Data

GSM connection is ongoing. In this mode, the power consumption

is decided by the configuration of power control level (PCL),

dynamic DTX control and the working RF band.

GPRS Idle

The module is ready for GPRS data transfer, but no data transfer

is going on. In this case, power consumption depends on network

setting and GPRS configuration.

GPRS Data

There is GPRS data in transfer (PPP, TCP or UDP). In this mode,

power consumption is decided by the PCL, working RF band and

GPRS multi-slot configuration.

EDGE Idle

The module is ready for data transfer in EDGE mode, but no data

is currently sent or received. In this case, power consumption

depends on network settings and EDGE configuration.

EDGE Data

There is EDGE data in transfer (PPP, TCP or UDP). In this mode,

power consumption is decided by the PCL, working RF band and

EDGE multi-slot configuration.

UMTS Idle

Software is active. The module has registered to the UMTS

network and the module is ready to send and receive data.

UMTS

Talk/Data

UMTS connection is ongoing. In this mode, the power

consumption is decided by network setting (e.g. TPC pattern) and

data transfer rate.

HSPA Idle

Software is active. The module has registered to the HSPA

network and the module is ready to send and receive data.

HSPA Data

HSPA data transfer is ongoing. In this mode, the power

consumption is decided by network setting (e.g. TPC pattern) and

data transfer rate.

Minimum

Functionality

Mode

AT+CFUN command can set the module entering into a minimum functionality mode

without removing the power supply. In this case, both RF function and USIM card will

be invalid.

Airplane Mode

AT+CFUN command and W_DISABLE# pin can set the module entering into

airplane mode. In this case, RF function will be invalid.
