So I literally have no idea where to start but I know what I want to make.
The goal is to somehow transmit 25mb/s of data across 15km with high penetration. Acceptable for reaching through trees and rocky areas in the mountains.
I would like to focus on lower frequencies like 1.3ghz or 2.4ghz but I know there are limitations to that frequency. I really don't have a clue where to start if someone could point me in a good direction that would be amazing.
I was thinking it would be cool to use 1.3ghz and transmit on multiple channels, then combine them all to get the desired data rate.
Again i'm super noob at this kind of stuff so please excuse my ignorance.
