6.3. Operation and Storage Temperatures
The operation and storage temperatures are listed in the following table.
Table 40: Operation and Storage Temperatures
1.
1)
Within operating temperature range, the module is 3GPP compliant.
2.
2)
Within extended temperature range, proper mounting, heating sinks and active cooling may be
required to make certain functions of the module such as voice, SMS, data transmission to be
realized. Only one or more parameters like Pout might reduce in their value and exceed the specified
tolerances. When the temperature returns to normal operating temperature levels, the module will
meet 3GPP specifications again.
