Note: 1.Refer to section6.6 for more information about industrial grade.
2.“√” indicates supporting. “×” indicates not supporting.
3. The 2nd harmonic of LTE B14 is not isolated completely from embedded GNSS
receiver, the interference would make GNSS de-sense seriously when LTE B14 and GNSS are
working simultaneously, the external GNSS receiver is recommended to use instead of
embedded GNSS in M18QA/M14QA.
