3.7.1.  WAKE_N Signal* 
The  WAKE_N  signal  is  an  open  collector  signal,  but  a  host  pull-up  resistor  and 
AT+QCFG="risignaltype","physical"  command  are  required. When  a  URC  is  returned,  a  low  level 
pulse will be outputted. The state of WAKE_N signal is shown below.

3.7.2.  W_DISABLE_N Signal* 
The module provides a W_DISABLE_N signal to disable or enable the RF function (excluding GNSS). 
W_DISABLE_N for RF function control is disabled by default, and AT+QCFG="airplanecontrol",1 can 
be used to enable the function.   
 
W_DISABLE_N is pulled up by default. Driving it low sets the module into airplane mode.   
 
Table 10: RF Function Status 
It  is  an  open  collector  and  active 
low signal. 
It allows the module to provide RF 
status indication via LED devices 
provided by the system.
