    How Ericsson is using Omniverse to simulate 5G network reception in a city


    The Omniverse is Nvidia’s “metaverse for engineers,” and Ericsson is using it to simulate reception for 5G networks in a six-block part of the city of Stockholm.To get more ericsson news, you can visit shine news official website.


    Ericsson is in the midst of building a “digital twin” for the city, or mapping it with all of its three-dimensional buildings and landmarks so that it can understand how 5G wireless signals — which can bring much faster wireless data and communications interactions — can bounce around the city and reach customers.The simulation will be so accurate that if a virtual tree is removed from Nvidia’s Omniverse — a virtual place with accurate physics where anything can be simulated — then it will have an effect on the wireless signals. Ericsson plans to use the data from the experiments to determine the best places to put its 5G network towers so they can serve millions of smartphones, tablets, and other internet-connected devices. Nvidia and Ericsson showed the project at the Nvidia GTC online conference today, which is expected to draw 200,000 attendees.


    There are more than 700 companies actively evaluating or using the Omniverse for enterprise purposes, said Richard Kerris, Nvidia vice president for the Omniverse platform, in an interview with VentureBeat.


    BMW is building a digital twin of a car factory, which it will eventually make in real life. The model has more than 300 accurate renderings of different cars, with robots, and digital humans all working together. But that’s a much bigger effort, while the Ericsson project can be built with a relatively small team, Kerris said.


    The Stockholm-based maker of telecommunications equipment is combining decades of radio network simulation expertise with Omniverse, a real-time digital-twin simulation and collaboration platform for 3D workflows. Ericsson is building city-scale digital twins to help accurately simulate the interplay between 5G cells and the environment for maximum performance and coverage, said Mathias Riback, head of standards and technology at Ericsson in an interview with VentureBeat.


    “We saw the potential to not only visualize but also simulate how a radio propagation environment would look like in a digital twin,” said Riback. “With radios, we have very complicated the physics on how radio waves propagate in the environment. The devil is in the details. In the old days, the only way to do this was to have more statistical models. It’s more or less impossible to predict performance or evaluate an algorithm or something very specific at a terminal location. But that’s what we can do with Omniverse.”


    As an added benefit, network engineers will soon be able to use virtual reality to examine the simulation in a live environment. They will be able to see the effects of moving objects, and they will also be able to teleport from one 5G tower to another much faster than they could do in real life. “The more details you can get there, the more real performance you can predict,” said Kerris.


    “We love the fact that developers are taking Omniverse and making it their own kind of context,” Kerris said. “When we first got introduced to the work that Ericsson was doing, and they brought to us how they were using the platform and ray tracing for what the project was, we were blown away, happily. The whole idea of that platform is it’s a developer platform, first and foremost, and you make it what you want it to do. And of course, true to reality simulation is at the very core of what we do. And so we think that digital twins is so applicable in so many different industries. And that’s the kind of thing that we get really excited about. The whole idea of this connective tissue between these virtual worlds is truly one of the things that Omniverse is designed for.”


    5G enables a multitude of new uses for wireless networks including IoT, manufacturing, self-driving cars, and telehealth. Networks serving these use cases operate in vastly different environments. New types of devices will enter the networks, and the number of devices will grow by orders of magnitude in the next few years.
