3. 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
out
the normal operating temperature levels, the module will meet 3GPP specifications again.
