My project goal is to have 2 devices, a transmitter and a receiver. The transmitter should transmitter a measured distance +- every second and the receiver which could be at max. 10 miles away from eachother should receive the data. Both do not have a static location. Every day their location could be changed. They would not have line of sight.
I am wondering which wireless technology would be best fit for this task. I've considered the following:
LORA: downside: coverage ( there might be no gateway )
RF: downside: range. The most long range module that i found was an Xbee pro 868 (Europe) which has a LOS range of 48km but urban range stated only 500m. Two highly different values but I wonder if it could archieve 10 miles non line of sight.
Cellular 2G/3G/4G/5G: downside: network topology (maybe also power usage but no strict constraints here). There can not be a point to point connection, there should be a server that stores the data and the receiver should poll the data (or am I wrong?).
Any advice on which technology to go for?
