NOTES
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
functions such as SMS*, data transmission, etc., without unrecoverable malfunction, effects on radio
spectrum or harm to radio network. Only one or more parameters like P
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.
