OpenHD - HD video, UAV telemetry, audio, and RC control
Latency should be around 110ms "glass to glass" based on my experience with "WifiBroadcast", which was an earlier (first?) thing to use Wifi in this way. (1) and a few related projects (2).It's a pretty clever hack, using Wifi without associating, but still using FEC (Forward Error Correction) and mirroring that to allow bi-directional communications for control/telemetry. Also allows RF diversity reception with multiple wifi adapters.I was experimenting with it for semi-local telepresence robotics for art/experiences. 
These projects are amazing in how much cheaper/more approachable/hackable they make all this vs. analog or proprietary digital video transmission.I'm not sure if OpenHD is directly related to WifiBroadcast/ I haven't had a chance to play with it yet (been meaning to for 6 months+), but it's at least using similar approaches with wifi (mis)use.There have also been some attempts to use the same approach with esp32 (etc) in a compatible way, though the link eludes me currently.(1)https://befinitiv.wordpress.com/wifibroadcast-analog-like-tr...(2) https://github.com/rodizio1/EZ-WifiBroadcast
