LTE-M coverage @ free sight


According to your Blog "LTE-M vs NB-IoT Field Test: How Distance Affects Power Consumption" the maximum distance between the base station and the Dev-Kit was 12km.

Do you know:

- The maximum distance for nRF9160 in free sight (e.g out at sea)?
  (The coverage maps from the network providers shows up to 40km from the mainland)

- The limiting factor for achieving longer distances using nRF9160?

- The maximum theoretical distance for LTE-M?
