Serious question, why not use current wifi for that kind of distance?

I know, it’s probably not really easy to make the comparison at this point - power usage is definitely part of that equation. Though the lower bandwidth of this doesn’t seem quite enough for video?

Edit: I misread the bandwidth as 347kbit, not Mbit. So yea, this looks very promising for video, especially given the limitations of Wifi, plus using less power.
