gamers worry about the latency of a wireless controller sending a signal from their couch to their TV.
for a fighter jet with a remote pilot, you're looking potentially hundreds of miles of range, and the latency of the video transmission to the pilot combined with the latency of the controls signal back to the plane. i can't imagine that being acceptable for any sort of dogfighting scenario.
- MayeulC 6y agoIronically, game controllers can have a latency of more than 20ms. Light travels more than 6000 km in a vacuum in 20ms. That's a pretty good excuse for gamers to complain about that sort of latency, I think.
- imtringued 6y agoBluetooth is bad enough that videos have to be delayed so that audio can catch up. Completely worthless for games unless you use proprietary codecs like aptX.
- MayeulC 6y agoI wouldn't say it's that bad, I flew a drone controlled via bluetooth with my phone, for instance. Buffering audio is actually a great answer to disconnections. Plus, it's less energy-intensive to fill the buffers at once than to stream it as needed. And since it's pre-recorded anyway, you already have the whole buffer. Yes, initial transfer can take a while, though. But in theory, the play/pause operations shouldn't have latency, and the bluetooth device could clearly communicate its state. I'm not sure how audio is actually implemented in the bluetooth stack, though, I've only ever done serial communication with it.
