1)
Operating temperature range ---- 3GPP compliant.
2)
Within 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 P

might
reduce in their value and exceed the specified tolerances. When the temperature returns to the normal
operating temperature levels, the module will meet 3GPP compliant again.
