10
Within operation temperature range, the module is 3GPP compliant.
11
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
out
might reduce in their value and exceed the specified
tolerances. When the temperature returns to the normal operation temperature levels, the module will meet 3GPP
specifications again.
