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.

3)
DFOTA function is only supported on B657 version or later.
