You can test this out by preparing a small enough 4K video (10:00 or a bit shorter) to your Dropbox or any other form of online storage service, and try to stream it using 4G. If you can watch your video just fine, then it is fine.

I personally don’t think 5G is that necessary for 4K, although speed increase definitely can help.

What about a 1 hour to 2 hour 4K video ?
 
That or do we need 5g ?
Depends entirely on network congestion and signal strength. If your LTE is slow due to weak signal from attenuation, 5G's going to be even worse. However, if your LTE is slow because of network congestion (particularly apparent during conventions, ball games and similar gatherings where you have masses of people using cellular data at the same time), then 5G will help a lot.

4K from streaming services is around 15Mbps. I get around 5 Mbps on LTE so definitely not enough. When I visit suburbs, I've sometimes seen 80 Mbps so I expect that would handle it just fine - that is if carriers ever allow it.

Netflix is 15+ Mbps. However, Apple’s 4K streaming can go north of 25 Mbps.

It really depends on the data speed you get on 4G. Also depends on the servers you’re streaming from. Any streaming platforms works on hops. So the more number of hops until you hit the server the slower it will be. There’s no generic answer.

My 4G speed easily hits over 50Mbps almost always so 4K shouldn’t be a problem for me on my phone. My broadband speed is above 30MBps on average as well so that would cater for 4K as well.

4K file sizes are massive. LTE networks all throttle down speeds when you're a heavy user, you wont get a pleasant experience trying to use it on LTE. you've got to use wifi.

Your right I tried today it would never load or barely.

I wish Air Video HD supported 4k files. Oh well.

It seems to always work.
 
Although it isn't streaming, I've gamed plenty of times off of my hotspot over Verizon's LTE. Latency is usually low and I'm not at a disadvantage. Games where milliseconds count like Rainbow Six Siege, Smash Bros, GTA5. Honestly as long as whatever app you're using keeps a good buffer of data ahead (VLC), streaming 4k is not an issue.

VLC on iOS doesn't work over the internet :( Unless I am wrong ?
