No. The low end stuff is basically beefed first stuff. I personally know some drone guys.
The higher end stuff uses sat and spread spectrum. It's used because it's hard for nation states to jam it.
I know a fair amount about these systems having used them (granted not for 20 years). A full and complete answer to this question could result in a person putting ITAR restricted information online though. A UAS is a system of systems including communications systems, payload systems, flight control systems, the air vehicle itself, etc. The way that each of these systems works and interacts with the other systems varies depending on the particular UAS you are looking at.
I agree with that
