As we are waiting for 5G connection to available worldwide, Samsung already working on 6G Technology and expecting the completion of the 6G standard by 2028.
Samsung founded the Advanced Communications Research Center in May 2019 to study 6G and these observations are part of the research.
Samsung released a white paper entitled “The Next Hyper-Connected Experience for All.” which details the company’s vision for the next-generation 6G communication network.
The Company Expected that the number of connected devices will reach 500 billion by 2030 and mobile devices will take various form-factors like augmented reality (AR) glasses, virtual reality (VR) headsets, and hologram devices.
Samsung 6G Perfomance Requirements
In order to realize advanced multimedia services such as truly immersive XR, mobile hologram, and digital replica, 6G needs to provide a much higher data rate than 5G. While 5G was designed to achieve 20 Gbps peak data rate, in 6G.
Samsung aims to provide the peak data rate of 1,000 Gbps and a user experienced a data rate of 1 Gbps. To provide advanced multimedia services to a large number of people, the overall network performance needs to be improved means 2x higher spectral efficiency than 5G.
Performance targets include air latency less than 100 μs, end-to-end (E2E) latency less than 1 ms, and extremely low delay jitter in the order of microseconds. With these criteria met, the user-perceived latency may be less than 10 ms, which is the motion-to-photon latency criterion for XR services.
For support of latency-sensitive services requiring extreme reliability, e.g., industrial automation, emergency response, and remote surgery, we intend to improve reliability by 100 times compared to 5G so that the error rate is 10−7
A comparison of key performance requirements between 6G and 5G is shown in the diagram below.
The architectural requirements of 6G include resolving the issues arising from the limited computation capability of mobile devices as well as implementing AI right from the initial phase of technology development and enabling the flexible integration of new network entities.
“While 5G commercialisation is still in its initial stage, it’s never too early to start preparing for 6G because it typically takes around 10 years from the start of research to commercialisation of a new generation of communications technology,”explained Sunghyun Choi, head of the Advanced Communications Research Center.
Three key 6G services: truly immersive XR, high-fidelity mobile hologram, and digital replica.
XR is a new term that combines VR, AR, and mixed reality (MR). It has attracted great attention and opened new horizons in various fields including entertainment, medicine, science, education, and manufacturing industries. Technical development to realize XR is still in progress, and new innovative technologies are constantly appearing.
These technologies require advanced device form-factors, such as hand-held components, to support mobile and active software content. Current mobile devices lack sufficient stand-alone computing capability.
Another challenge is sufficient wireless capacity. Note that current AR technology requires 55.3 megabits per second (Mbps) to support 8K display (with one million points), which can provide enough user experience on a mobile display. However, in order to provide truly immersive AR, the density should be largely improved and it will require 0.44 gigabits per second (Gbps) throughput (with 16 million points). In addition, XR media streaming may have similar demands to 16K UHD (Ultra High Definition) quality video.
For example, 16K VR requires 0.9 Gbps throughput (with a compression ratio of 1/400). The current user experienced data rate of 5G is not sufficient for seamless streaming. It is expected that the market sizes for VR and AR will reach $44.7 billion and $87 billion, respectively, by 2030
