3 Operating Characteristics
3.1. Operating Modes
The table below briefly summarizes the various operating modes of RM500Q-AE and RM502Q-AE.
Table 6: Overview of Operating Modes
3.1.1. Sleep Mode
DRX of module is able to reduce the current consumption to a minimum value during the sleep mode, and
DRX cycle index values are broadcasted by the wireless network. The figure below shows the relationship
between the DRX run time and the current consumption in sleep mode. The longer the DRX cycle is, the
lower the current consumption will be.
Software is active. The module has registered on the network, and it
is ready to send and receive 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.
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.
The module keeps receiving paging messages, SMS, voice calls* and
TCP/UDP data from the network with its current consumption reducing to the
minimal level.
In this mode, the power management unit shuts down the power supply.
Software is inactive, all application interfaces are inaccessible, and the
operating voltage (connected to VCC) remains applied.
