Good morning/afternoon Mark
Good questions. The main reason for choosing LoRa. The main reason for choosing LoRa is its receiver sensitivity which is -148 DBM. This let us a use a $6 device on a LEO satellite close the link with an omni gain antenna on the ground. This can be done in a 10 KHZ channel. I also believe this can be used in part 97 of the FCC rules. It might require a rule waver but I believe it is doable.
The negative is as you point out is it is proprietary however there are 10 of million of the devices in operation globally.
In summary given it sensitivity and low cost it is a good choice.
Can you suggest a better choice ?
