Thank you for the links @hallowed31 @zwieblum , I will read them shortly and revert back the soonest.
@srnet thank you for the advise!
There is also this from Xbee

From the data sheet they should easily handle my data rate, and the distance. though I will check the alternative and to a proper technical comparison.
@srnet I've seen your remarks on many of the topics that I've read, I would like to incorporate a camera of around 2 Mp to get a video tramission as well to the ground station (just cz its cool no scientific purpose behind this), and the team at the university already purchased a microcontroller arduino nano, which I know can't handle a camera, so I was thinking on using an ESP32-cam and connect it to the nano. However if I want to propose changing the nano controller, can you confirm that the Uno can handle the 2 Mp camera?
