    No one can give you a accurate number as it depends on the environment, your antennas etc.

    You can usually get 5Km if you have line of sight at 14dBm, more if the one or both devices are at high altitude. It’s possible to manage 15Km+ under very strict conditions.

    However in an urban, busy, environment without line of sight it can quickly drop to 200 meters… so it’s quite sensitive to path attenuation, interference, etc.

    EU regulations limit transmissions in this 868Mhz band to 14dBm so I haven’t tested on 20dBm.
