Telepresence and Remote Control

The same benefits from 5G which could unlock cloud-rendering of interactive content could also make for more viable immersively operated remote control for things like vehicles, surgical robots, and remote avatars.

Again, latency here is key. Remote control obviously exists today, but there are some use-cases where latency is too high to be viable or safe.

Take remote vehicle control, for instance. In the future, real operators may need to occasionally drive autonomous cars manually in cases where AI systems have failed. Rather than send someone physically to the car, an operator could connect remotely to the vehicle to become a ‘virtual’ driver. Control latency here would need to be very low to make this safe. It’s easy to understand how this extends to other latency sensitive use-cases like robotic surgery or remote avatar control.

Easier Content Snacking and a Bigger Pipe for WebXR

This is the only one that’s about pure bandwidth. As median internet speeds increase, use-cases evolve to make use of it. You probably wouldn’t have watched that last funny YouTube video if you had a 56k connection and had to wait an hour for it to buffer, but sufficient bandwidth makes content consumption more fluid and lowers the bar on what you’re willing to watch because the payoff doesn’t need to be high if the wait is low.

If 5G makes a bigger pipe more readily available, it can reduce the friction of using VR and AR by making it that much faster to get your head into the content. Take the recently released Asgard’s Wrath, a highly anticipated VR game which clocked in at 121GB. For many folks with slower connections, this massive size meant starting the download when they got home from work and not being able to start it until the next day.

More bandwidth on average reduces this friction and makes content more snackable since users don’t need to spend as much time to sample the content being offered to them.

This could especially be a boon to WebXR, which delivers AR or VR directly through the web browser, very similar to how websites are accessed. Because WebXR content isn’t pre-downloaded like a game or video, it needs to be small enough in size that the user doesn’t sit through a painful wait while the experience loads. With greater bandwidth, WebXR experiences can be made larger and with greater detail, and it would be more seamless to jump from one WebXR experience to the next without long waits.

5G is Latency & Bandwidth, But Execution & Economics Are Still Key

And that’s about it… along with any other use-case you can imagine where the key barrier is latency and bandwidth. Those are the pieces you should come back to any time that someone throws any technology and 5G into a sentence and tries to explain how 5G is going to revolutionize that technology, industry, or use-case.

Is anything unlocked by reducing latency and increasing bandwidth? When it comes to AR and VR, the answer is yes in theory, but execution and economics are equally important.

5G will definitely open up the possibility of the use-cases described above, but possibility doesn’t always mean viability. It might be possible to, for instance, deliver a good cloud-rendered VR experience thanks to the benefits of 5G, but how much are users willing to pay for this, and is it greater than the cost to run such a service?

These are big questions which to date only have rough answers. It will take the slow rollout of 5G into the market before the actual bandwidth, latency, and costs are known, and only then will the line be clear between the possibility and viability of various use-cases.

    Great article; nice to see some reality checking on 5G. I’m surprised you didn’t mention AR more though. While there’s probably even less reason to remotely render frames for AR than VR, it’ll likely be accessing large datasets such as point clouds. Also way more likely to be mobile.

      fast internet connection for ar will be a must have if a lot of people want to see the same thing …especially when interacting with that thing ….like ar laser tag arena with 100 people with virtual obstacles and avatars and some skeleton npcs or whatever
      ….the old simple way with a few hololenses was one hololens is like the server coordinating everything and a few can join in with interactive app

      • Graham J ⭐️

        That’s a great point. If multiple people see an overlay at a static position then the latency of the apperence of the overlay would be the server to observer latency. But worse, if the overlay is over a remotely tracked object (like another user) there would be additional positional latency.

        You’re quoting some wild anti-science nonsense. Hell, your linked article calls cell phones “radioactive” in the opening sentence. It also swaps around between “proven harmful” and “never tested on humans” depending entirely on which stance is more supportive of the argument it is making. And uses the phrase “EMR poisoning”, which is a bad joke(poisons are chemical compounds. It is why people exposed to high levels of particle radiation have “radiation sickness” and not “radiation poisoning”).

        “4G” had no effect on myopia, and if you want to claim otherwise, you need to find a plausible mechanism by which 700-2100 MHz radio waves can cause nearsightedness as well as an explanation for why it only happens when using 4G data encoding(as the frequencies have been in widespread use for a long time).

        Also, cell phones are not high-power microwave transmitters. They are, in fact, quite low-power radio transmitters.

          Actually that’s not the case, its the opposite. The leaders in insurance and leaders in telecoms at the European and American fund level are asking a lot of questions, there are a lot of quality people out there, you would be surprised, they are informed and when they are not they know it and are proactive in reaching out for correct information from ALL source not just BB FT, Reuters .

          Insurance people in particular are a little worried to the point of just laughing about it as unbelievable with a fearful look on their face, dear in the headlights. BIAS or preference means little when professionals look at some thing and high quality choice has to be made.

          The ideal would be roll out 5g, stuff like IOTA, whole internet up to ipng (v6) man kinds progress at accelerated pace since it was stunted, but if people start getting massively impacted, not just blurry eyes, dulled sense of well being, mental focus, slight impact on cellular vitality, but actual full bore major health impacts which are directly measurable. That’s not going to work, the internet enables mass information sharing and communication, 5G already has a red flag over it, the data is going to be being watched closely, you tube will exploded with a million videos, face book,

          People like to go strong both directions of like recommend and other side of the stick.

          With are beings which are electrical first then chemical.

          If 5G has to roll out it has to roll out end of story, but people will need options to alleviate or remove any major or minor irritation.

            Your belief has no effect on reality nor will it save you from eternal hell. Life coming from nothing/no life is whats never existed. Everyone knows life is a creation.

          • Graham J ⭐️

            No one’s beliefs have any effect on reality; why would they? Life formed because conditions were amenable to it but that is irrelevant because the universe existed for billions of years before that. Some choose to make up reasons for the universe being the way it is but rational people follow the evidence.

          • care package

            Your rational, just ask you lol. Nice job preaching your belief system/religion there though. There is no evidence the earth is billions of years old, nor is there regarding your fantasy ‘life formed because conditions were amenable to it’. That takes more faith than believing life was a creation.

          • Graham J ⭐️

            Of course there is evidence. Learn science. You’re the one preaching a belief system.

          • care package

            Love it when evo’s just play the ‘science’ card. Evolution has nothing to do with science. Science is observational, and as far as the ‘science’ behind ‘billions of years’ radio dating methods are all extremely flawed. Results are always all over the place and the preferred one is cherry picked. Science is also repeatable, which radio dating is too inconsistent to be reliable. Its still all pushed because most in this world hate truth.
            As far as preaching hell yes I am, and so does every evo proclaiming their faith.

          • Graham J ⭐️

            Who said anything about radioisotope dating? Although I love the irony of someone who believes the universe was created by some magical sky being complaining about the accuracy of measurement tools, all one needs is a telescope. Or do you not believe in refractive optics or the speed of light either?

            Science isn’t a card, it’s the study of reality. I guess it’s no surprise you don’t understand it.

          • care package

            I said something about radioisotope dating, or did you not catch that. I brought it up because that’s what evo’s use for billions of years, and their best argument for evolution is homology. Of course you finish with an “i just don’t understand it’ jab. So far, all you’ve done is express your opinions and preached your religion offering zero actual insight. good job.

    • Graham J ⭐️

      That’s not what edge means.

  • Miguel Arjona Villanueva

    Nice article but I have to disagree in one point regarding Cloud Rendering. Your are right when you say that latency increases with the distance, but alternatively you can use Edge Computing (or you will) to ensure that latency from the sever is less than 10ms (should be enough). We have demonstrated it in the last Vodafone 5G European Forum trasmittting a high quality of digital twin of a real factory in real time from the Edge through 5G to an Oculus Quest headset

    • benz145

      Edge computing and 5G go hand-in-hand:

      That is to say that a single data center in the middle of the continental US, for instance, would have too much latency by the time it reaches the country’s coasts for a viable cloud-rendered experience experience. A distributed cluster of capable data centers (also known as ‘edge computing’) is the key to making this viable; 5G helps by expanding the ‘coverage’ of capable data centers by reducing latency, while high bandwidth makes greater quality imagery possible in this use-case (which will be increasingly important as the resolution of VR and AR devices increase).

    • Larry

      AFAIK there are zero real world 5G tests showing sub 15 ms latency.
      All of the real world tests show 20 to 30 ms which is far too slow for
      VR. 4G latency in the US is 40 to 60 ms, it’s impressive they managed to
      cut that in half.

      Yes, there are lots of demonstrations and lab experiments with low latency 5G, but that’s not the real world.

      If you have data showing real world tests, please post it.

      • Miguel Arjona Villanueva

        Using Edge Computing the XR Rendering Server is installed a close as possible to the final user (even a few kilometers) so you can get latencies under 10 ms. Of couse, Edge Computing from Teclco is under development but the tests in real environment shows that it is (or will be) possible. In the image you can see a digital twin of a factory sent to an Oculus Quest with the same quality than HTC Vive using 5G https://uploads.disquscdn.com/images/8b01a6c6b5a6815c1bee35becc655eba4ffec4aaff83ddfa53ab201edf51ac48.png

          Like I said, that’s a very nice demo. Nobody is going to finance and build and operate billions of dollars worth of edge computing hardware for a very small market of a few million VR users.

          • Miguel Arjona Villanueva

            Maybe NVDIA in thinking on it: NVIDIA CloudXR (in Cloud but applicable to Edge)

  • Larry

    Real world latency testing on 5G is showing 20 to 30ms. Better than the 40 to 60ms typical in US cities but nowhere near as fast as claimed (not a surprise) and obviously far too slow round trip times for any VR application or edge rendering. The claims of sub 5ms latency on 5G are just fantasy.

    As the article says, the idea of VR + 5G is mostly overhyped marketing. VR has enough challenges without being lumped in with 5G.

    • benz145

      It depends what you’re testing. The super low latency claims are to the ‘edge’ of the network (the nearest node). That’s why edge computing is such a key part of making this possible.

      • Larry

        Yes, that’s the vision Intel pushed when they were in the 5G space. What they don’t say is that deploying that level of computing to the ‘edge’ will cost many billions and require data centers everywhere. It’s also completely backwards to the current model of data centers which is to put them centrally where power and real estate is cheap. VR itself is niche enough with only a few million users, no company is willing to invest billions in edge rendering on the very small chance that this will suddenly appeal to consumers. If VR was so compelling, more people would be buying the Quest etc.

        • benz145

          Yup, that’s a central point here; edge computing is necessary and the economics need to make sense too. Granted, it looks like there’s a lot of money being poured into non-VR game streaming services, and these will need to make use of edge computing too if they’re going to take off with hardcore gamers; VR and AR cloud-rendering will likely benefit from those investments.

      • Baldrickk

        When Steam link over local wired gigabit at only 1080p isn’t fast enough to not overcorrect in flat screen racing games, there’s no way an internet based streaming service is ever going to be low latency enough to support VR.
