I have a similar question regarding the LoRa range between an RS3 Base and Rover pair. I need to shoot the profile of a remote 2 km stretch of small stream located in rather narrow canyon that has a bit of a dog leg midway down the valley. I can probably set the Base on a hillside near the mid point (and almost keep line of site between the RS3s) but the Base will be a couple hundred feet above the valley floor. At its farthest point, the Rover won’t be much more than a km from the Base.
I know very little about radios, but in the past I’ve had issues with robotic total station radio transmissions to a data collector when the data collector dropped below the total station and below/behind a shoulder in the terrain. I was told that problem was due to some sort of “loop” in the total stations transmitted radio signal that didn’t like having the data collector below the transmitting total station with a ground surface in the way. Does the RS3’s LoRa transmission have any similar issue (e.g. the Rover being below the Base and potentially a bit behind a ground surface) that I should be aware of that would limit the distance I can operate the Rover from the Base? Thanks.
