1.  "*" means under development. 
2. 
1) 
Within operating temperature range, the module is 3GPP compliant. 
3. 
2)
 Within extended temperature range, proper mounting, heating sinks and active cooling may be 
required to make certain functions of the module such as voice, SMS, data transmission, emergency 
call to be realized. Only one or more parameters like Pout might reduce in their value and exceed the 
specified  tolerances.  When  the  temperature  returns  to  normal  operating  temperature  levels,  the 
module will meet 3GPP specifications again.
