Ocusync has been out for some time now and it already sounds like magic. I think when compared to wifi or some radio bridges it usually operates in much less congested environment. Nonetheless, if you think about frequencies used, energy going down with r^2 and bandwidth they are doing, it's an amazing feat even in ideal conditions. And here's it's a moving object, on battery, with four electromagnets around it.
My son has a Mini2, the transmission range on this is pretty amazing.
We were watching a neighbor's house over the holiday, which meant mostly checking for delivery boxes on their porch and putting them inside. We could drive the Mini2 out the window of our house and 2 blocks away to check the porch without getting out of our seats. And this is a suburban area full of houses, trees, and a shit ton of interference at the wifi/4G/LTE ranges. The video never lost a frame.
Boasting about flying beyond line of sight without a spotter in a cluttered residential neighborhood isn't going to score you many points among the drone enthusiast crowd.
No worries. If there's just one thing I want to get across though, it's that as drone operators, we are collectively responsible for how the broader community views us and drones.
Random drones floating through neighborhoods is sketchy from a safety standpoint but also it tends to upset people, who often think that any drone they see is spying on them. Just a consideration.
Personally I like to fly around abandoned buildings and decrepit structures. Lots of interesting flying to be done and cool vids to be taken, and there's nobody around to complain :)
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.
I don't think so, at least not outside of the channel bandwidth - based on the FCC filings and the observed behavior, initialization seems to happen on 5839MHz (Channel 8) and then the device hops to a user-selected channel, where it seems to stay.
