3.3.2. 

Host Radio Disable Operation 

Two additional control signals are used to disable the radio on the module. The 
signal W_DISABLE#1 is allowed to disable the WWAN of and the signal 
W_DISABLE#2 is allowed to disable the GPS of LN940 M.2 Module in order to 
meet public safety regulations or when otherwise desired implementation of 
this signal is required for systems and all add-in card that implement frequency 
capabilities.
