Quectel BC65 - Functional Diagram

NB-IoT Module Series
BC65 Hardware Design
BC65_Hardware_Design 12 / 55
1.
1)
Within the operating temperature range, the module meets 3GPP specifications.
2.
2)
Within the extended temperature range, the module keeps the ability to establish and maintain
functions such as SMS*, data transmission, etc., without any unrecoverable malfunction. Radio
spectrum and radio network will not be influenced, while one or more specifications, such as P
out
,
may undergo a reduction in value, exceeding the specified tolerances of 3GPP. When the
temperature returns to the operating temperature range, the module will meet 3GPP specifications
again.
