LTE Module Series
EC25 Mini PCIe Hardware Design
EC25_Mini_PCIe_Hardware_Design Confidential / Released 17 / 46
1. “*” means under development.
2.
1)
Within operating temperature range, the module is 3GPP compliant.
3.
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 operating temperature levels, the module is compliant with 3GPP specification again.
