This has been out for a few years in the form of the "DJI FPV" system, Goggles and Air Unit, for DIY drone construction. It's not science fiction - the latency and bitrate taper off a bit at range, but it genuinely works. If you tear down the hardware, it's using an Imagination IE1000 802.11ac frontend, Skyworks amps, and a custom DJI image processor chip (marked P1). So the air protocol probably looks somewhat like 802.11ac (OFDM etc.) but without the framing overhead and presumably without TCP/IP.
