1)
Within operation temperature range, the module is 3GPP compliant.

ithin extended temperature range, the module remains the ability to establish and maintain a voice,
SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There are also no
effects
on radio spectrum and no harm to radio network. Only one or more parameters like Pout might
reduce
in their value and exceed the specified tolerances. When the temperature returns to the normal
operati
ng temperature levels, the module will meet 3GPP compliant again.
