Understanding the 5.8 GHz RC communication on PV2+

[kevin0816]

Hey guys, I hope you guys can help me. I am currently working on a little project at home to help extend the range of my PV2+ but I really don't understand how the drone uses the 5.8 GHz RC control to do it and how it processes the signal and tells the drone to move around. I've done a little research different methods that are used for communication in RC quad-copters but I am still cloudy on the idea. I hope anyone on here has more insight in the 5.8 GHz communication between the drone and the controller.
