5G use cases

10 Sep
With 5G promising “ultra-high throughput, ultra-low latency transmission, and edge computing”, Huawei and Softbank’s 5G use cases including real-time UHD video, robotic arm control and more.

Seeking their own slices of 5G supremacy, Japan’s Softbank Corp and the Japanese division of China’s Huawei Technologies have “jointly demonstrated various potential use cases for a 5G network.”

As can be seen by the two photos provided at the end of this article, the demonstration “included real-time UHD video transmission using ultra-high throughput, remote control of a robotic arm using ultra-low latency transmission and remote rendering via a GPU server using edge computing.”

In addition, the real-time UHD video transmission demonstrated throughput of “over 800 Mbps.”

The videos show a game of air Hockey being played, with a description of how this works in example 3, below.

The remote control of the robotic arm also demonstrated an “ultra-low latency one-way transmission of less than 2ms.”With SoftBank planning “various experiments to study 5G technologies and endeavouring to launch 5G commercial services around 2020,” it’s clear these kinds of demonstrations are just a glimpse into what is promised to be a glorious 5G future.

Of course, 5G promises to connect everyone to everything, everywhere, especially via a vast array of IoT devices, so security is still a major issue needing to be solved, but as with the final 5G standards, a lot of work is being done in all these regards to deliver solid solutions backed by superior security, and we’re just going to have to wait and see how successful the industry is at these issues.

As for the edge computing mentioned above, Huawei and Softbank state that, “in edge computing, servers are located near by base stations, i.e. at the edge of an mobile network, with a distributed way.”

The dynamic duo state that “This architecture allows us to realise ultra low latency transmission between the servers and mobile terminals. Also, it is possible to process a huge amount of data gathered by IoT devices to decrease the load of the mobile network.”

Here are the demonstration details provided by both companies, with accompanying infographics:

1. Real-time UHD video transmission

“A UHD camera was installed inside the demonstration room to capture outdoor scenery. The data from this camera was then compressed in real-time using an encoder and transmitted through the ultra-high throughput 5G network to a UHD monitor via a decoder, where the original data was recovered.

“In this demonstration, the scenery of the Odaiba Tokyo Bay area was successfully displayed on the UHD monitor using the ultra-high throughput provided by the 5G network. This technology can be applied to various industries, including tele-health or tele-education.”

2. Immersive video

“Scenery was captured by a 180-degree camera equipped with four lenses pointing four different directions installed in the demonstration room, and captured scenery was distributed to smartphones and tablets over the 5G network.

“Four separate cameras were set up to capture the scenery in different directions, and the video images captured by these cameras were stitched together to generate a 180-degree panoramic video image that enabled multiple simultaneous camera views. Then the video image was compressed and distributed to smartphones or tablets in real-time over the 5G network, which gives users a truly realistic user experience.

“Coupled with a 5G network, this technology can be applied to virtual reality (VR) or augmented reality (AR).”

3. Remote control of robotic arm with ultra-low latency

“A robotic arm played an air hockey game against a human in this demonstration. A camera installed on top of the air hockey table detected the puck’s position to calculate its trajectory.

“The calculated result was then forwarded to the robotic arm control server to control the robotic arm. In this demonstration, the robotic arm was able to strike back the puck shot by the human player on various trajectories. This technology can be applied to factory automation, for example.”

4. Remote rendering by GPU server

“Rendering is a technology used to generate videos or images using computers with GPUs (Graphic Processor Unit). This technology is used for generating HD videos in computer games or for CAD (Computer Aided Design). The rendering consumes a large amount of computing resources. Therefore, HD computer games or HD CADs were not executable on tablets or smartphones on their own.

“However, edge computing technology provided by the 5G network allows us to enjoy HD computer games or HD CADs on tablets or smartphones. A GPU server located near a 5G base station performed rendering and the image generated by the GPU server was sent to the tablet over the ultra-high throughput and ultra-low latency 5G network. This technology can be applied to check the CAD data at a construction site with a tablet or to enjoy a HD game application on a smartphone.”

Huawei and Softbank note that: “Immersive video” and “remote control of a robotic arm with ultra-low latency” were jointly integrated and configured for demonstration by SoftBank and Huawei. “UHD real-time video transmission” and “Remote rendering with GPU servers” were integrated and configured for demonstration by SoftBank.
