Ryu, I like that!
Long range antennas will show up on ARA eventually. LTE direct may be another option we will see popping up in 2016. In the US, most of the "good spectrum" is owned by large corporations or the military. In other countries it might get really interesting where advanced spectrum is more accessible or cheaper to acquire. I've been thinking about idea of robots controlled by ARA, their processors upgradable as modules. I imagine a Boston-Dynamics robot powered by an ARA in its chest!
HAM radio module could also be interesting (if power permits), where a huge antenna could stick out attached to a battery pack. in the 1980s HAM radio people operated a FREE packet radio network where "HAMmies" could send packets across the country. The internet replaced that in the 90s, But I think they were on to something.
Software Defined Radios may eventually show up on ARA (the idea that a radio can operate on many frequencies and is only limited my software). But today the hardware is expensive and one can get into a lot of trouble with these! .....
More on your idea: the US military actually uses X-Box controllers to run drones, it allows recruits to learn advanced drone operation in minutes!
What else would you do with a long distance radio?
