LTE Standard Module Series
EC25 Hardware Design
EC25_Hardware_Design 21 / 112
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 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
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.
