NB-IoT Module Series
BC95 Hardware Design
BC95_Hardware_Design Confidential / Released 11 / 51
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 an
SMS*, data transmission, 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 P
out
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.
