Let's say I want to use a raspberry pi for a research project. The raspberry pi would be placed in a secure case(power has been taken care of and is not an issue). However, it will be in the middle of a desert more than 50 mi away from wifi or cellular.

What would be my best solution to receiving data from the raspberry pi? Is there some sort of antenna setup that can broadcast a signal far enough to be picked up by me at my house that is about 50 mi away?

    your question is not a RPi question ... it is a remote communication question – jsotola May 26 '18 at 3:54

    What about a gsm module? – Harcker May 26 '18 at 9:46

    @BitcoinM: I think your range requirement (50 mi) will push you beyond the "practical" realm of wifi. The 2.4 GHz carrier freq will have more losses than lower freq bands. But good news is in stock for RPi: Google "software defined radio raspberry pi", and check out this site. – Seamus May 26 '18 at 13:38

    @BitcoinM, the "similar" question that you reference asks if you can add an antenna to the RPI3 board .... it is a direct RPi question that is not similar to yours at all – jsotola May 26 '18 at 15:52
