5g is basically a marketing term because marketing droids demand the version number increase. It’s a worse technology with terrible range among other things. There is no guarantee 5g will have any better latency than 4g in the real world. Bandwidth (*bps) is not latency. Ping is how you measure latency.
See Verizon’s real world deployment is 30ms… And that is their official number which means the real one is probably far worse. That’s worse than many 4g deployments. Rumor has it Huawei’s 5g equipment is the only good 5g equipment and that’s the primary reason it can’t be sold in the US.
There is a reason the new iPhone doesn’t have 5G and I’m betting the next won’t either. A pox on 5G.
Ok. Well maybe you can say 5g is not mature enough to be ready for this sort of application :/ It’s true and you can demonstrate it. You might reduce latency with a dedicated 4g lte modem as opposed to a cell phone. The tethering step ads some latency, even over USB. You could also try another streaming protocol and/or reading the documentation for every element in your pipeline.
Fwiw if you want high quality, really low latency, drone control, DJI makes some great gear specifically for that and flight controllers so you won’t lose your drone. Their software is excellent as well… But that’s neither 4G not 5G. If should work fine with Nano, however.
To my understanding current 5G networks are “none-standalone” implementations and still use 4G technology underneath.That explains that you see same latency as with 4G. First “standalone 5G” implementations are to be expected in 2020…
