NOTE
- 1) Within operation temperature range, the module is 3GPP
- 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 Pout 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.
- “*” means under development.
