6.3. Operation and Storage Temperatures
The operation and storage temperatures are listed in the following table.
Table 31: Operation and Storage Temperatures
Parameter Min. Typ. Max. Unit
Operation Temperature Range
1)
-35 +25 +75 ºC
Extended Temperature Range
2)
-40 +85 ºC
Storage Temperature Range -40 +90 ºC
1.
1)
Within operation temperature range, the module is 3GPP compliant.
2.
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 Pout 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.
3. “*” means under development.
