Note: The sensitivity level has deviation of approximately +/- <2dB,
device and channel because the level shows a typical value.
The sensitivity level of the NR bands has a deviation of approximately
+/- <3dB depending on the EN-DC combinations, but the combined
sensitivity performance meets the 3GPP requirements.
LTE level is measured at BW 10 MHz except Band 46
B46 BW = 20 MHz

Environmental Requirements
2.8.1. Temperature Range
Mode Temperature Note
Operating Temperature Range
–20°C ~ +55°C
This range is defined by 3GPP (the global
standard for wireless mobile communication).
Telit guarantees that its modules comply with
all 3GPP requirements and that it has the full
functionality of the module in this range.
–40°C ~ +85°C
Telit guarantees full functionality within this
range as well. However, there may possibly be
some performance deviations in this extended
range related to 3GPP requirements, which
means that some RF parameters may deviate
