4
Within operating temperature range, the module meets 3GPP specifications.
5
Within extended temperature range, the module remains the ability to establish and maintain functions such as voice,
SMS, data transmission, etc., without any unrecoverable malfunction. Radio spectrum and radio network are not influenced,
while one or more specifications, such as P
out
, may exceed the specified tolerances of 3GPP. When the temperature
returns to the operating temperature range, the module meets 3GPP specifications again.
