3 Operating Characteristics
3.1. Operating Modes
The table below summarizes different operating modes of the module.
Table 6: Overview of Operating Modes
See document [4] for more details about the AT command mentioned above.
3.2. Sleep Mode
In sleep mode, DRX of the module is able to reduce the power consumption to a minimum level, and DRX
cycle index values are broadcasted by the wireless network. The figure below shows the relationship
between the DRX run time and the power consumption in sleep mode. The longer the DRX cycle is, the
lower the power consumption will be.
Mode Details
Normal Operation Mode
Idle
Software is active. The module has registered on the
network, and it is ready to send and receive data.
Voice*/Data
Network connected. In this mode, the power consumption is
decided by network setting and data transfer rate.
Minimum Functionality
Mode
AT+CFUN=0 command sets the module to a minimum functionality mode
without removing the power supply. In this mode, both RF function and
(U)SIM card are invalid.
Airplane Mode
AT+CFUN=4 command or driving W_DISABLE1# pin low will set the
module to airplane mode. In this mode, the RF function is invalid.
Sleep Mode
The modules keep receiving paging messages, SMS, voice*
calls and
TCP/UDP data from the network with its power consumption reduced to the
minimal level.
Power Down Mode
In this mode, the power management unit shuts down the power supply.
Software is inactive, while all interfaces are inaccessible and the operating
voltage (connected to VCC) remains applied.
