LPWA Module Series
BC66-NA Hardware Design
BC66-NA_Hardware_Design 15 / 59
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 normal operation
temperature levels, the module will meet 3GPP specifications again.
3. "*" means under development.
