LTE Standard Module Series
EC200T Series Mini PCIe Hardware Design
EC200T_Series_Mini_PCIe_Hardware_Design 16 / 54
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, 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.
