Temperature range
Operating
Temperature Range
-20 ~ +55°C :
This range is defined by 3GPP (the global standard for
wireless mobile communication). Telit guarantees its modules to
comply with all the 3GPP requirements and to have full functionality
of the module with in this range.
extended temperature -40 ~ +85°C
& commercial temperature 0~+70°C:
Telit guarantees full functionality within this range as well. However,
there may possibly be some performance deviations in this extended
range relative to 3GPP requirements, which means: some RF
parameters may deviate from 3GPP specification in the order of few
dB. For example: receiver sensitivity or maximum output power may
be slightly degraded.
Even so, all the functionalities like data connection, SMS , USB
communication, UART activation etc. will be maintained, and the
effect of such degradations will not lead to malfunction.
