Functional Diagram - Quectel UG89 Hardware Design

NOTES
1)
1. Within the operation temperature range, the module is 3GPP compliant.
2)
2. Within the extended temperature range, the module remains the ability to establish and maintain
a voice, SMS, data transmission, emergency call, 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 might reduce their value and exceed the specified tolerances. When the temperature
out
returns to the normal operating temperature levels, the module will meet 3GPP specifications again.
3. "*" means under development.
