1.
1)
Within operation temperature range, the module is IEEE compliant.
2.
2)
Within extended temperature range, the module remains the ability for data transmission. 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 IEEE compliant again.
