5 Reliability and Electrical 
Characteristics 
 
5.1. Operating and Storage Temperatures 
 
The following table lists the operating and storage temperatures of the module.   
 
Table 25: Operating and Storage Temperatures 
 
 
1. 
1) 
Within operating temperature range, the module is 3GPP compliant. 
2. 
2) 
Within  extended  temperature range, the module  maintains  functions such as  SMS  and  data 
transmission, without any unrecoverable malfunction. Radio spectrum and radio network will not be 
influenced, while one or more specifications, such as Pout, may exceed the specified tolerances of 
3GPP. When the temperature returns to the normal operating temperature level, the module will 
meet 3GPP specifications again. 
 
5.2. Current Consumption
