Product Info
LTE Standard Module Series
EC25 Series Hardware Design
EC25_Series_Hardware_Design 21 / 126
1.
1)
Within operating 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 operating
temperature levels, the module will meet 3GPP specifications again.
3. “*” means under development.
2.3. Evaluation Board
In order to help customers develop applications with EC25 series, Quectel supplies an evaluation board
(UMTS & LTE EVB), USB to RS-232 converter cable, earphone, antenna and other peripherals to control
or test the module. For more details, please refer to document [8].
