Within operating temperature range, the module is 3GPP compliant.
7
Within extended temperature range, the module remains the ability to establish and maintain a voice, SMS, data
transmission, 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 operating temperature levels, the module will meet 3GPP specifications again.
