is the I/O power domain of the module.
6.4. Operating and Storage Temperatures
Table 33: Operating and Storage Temperatures
1. The restricted operating temperature range is -30 °C to -20 °C, +60 °C to +70 °C .
2.
1)
To meet this operating temperature range, you need to ensure effective thermal dissipation, for
example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range,
the module meets 3GPP specifications.
3.
2)
To meet this extended temperature range, you need to ensure effective thermal dissipation, for
example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range,
the module remains the ability to establish and maintain functions such as voice, SMS, emergency
