I'm clueless, I'm new to radio stuff, so I'm not sure
Yeah it's a weird area of electronics sometimes. There's a really popular wireless communication chip called XBee that takes care of a lot of the lower level shit for you so you don't have to worry about many many things.
you'll need to do a lot of research, but this is a good place to start https://www.sparkfun.com/pages/xbee_guide
