5G internet technology has gotten a lot of attention in the news over the past year or so, but many people don’t even know what it means. 5G stands for 5th Generation, in reference to the 5th technological iteration of the internet.
As we should expect, there are already companies working on the 6th generation, even though the 5th generation has not rolled out yet.
On July 14, 2020, Samsung released a white paper titled “The Next Hyper-Connected Experience for All.” The paper outlined the company’s vision for the next generation of the internet. The white paper discussed many different aspects of the technology, including technical and societal megatrends, new services, requirements, candidate technologies, and an expected timeline of standardization.
Sunghyun Choi, Head of the Advanced Communications Research Center, says that the development of a new generation for the internet typically takes about ten years, and they are already at work on the next generation.
“While 5G commercialization 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 commercialization of a new generation of communications technology. We’ve already launched the research and development of 6G technologies by building upon the experience and ability we have accumulated from working on multiple generations of communications technology, including 5G. Going forward, we are committed to leading the standardization of 6G in collaboration with various stakeholders across industry, academia and government fields,” Choi said.
Samsung said that they don’t expect 6G to be commercial available until at least 2028, but they are beginning to roll out their road map now. The white paper noted that both humans and machines will be the main users of 6G, and 6G will be characterized by the provision of advanced services such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica.
The diagram below shows a comparison of the difference in performance requirements between 5G and 6G. The primary difference is that 6G performance requirements are a peak data rate of 1,000 Gbps (gigabits per second) and air latency less than 100 microseconds (μs), 50 times the peak data rate, and one-tenth the latency of 5G.
Samsung also expects to see AI applications for 6G.
“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. The trustworthiness requirement addresses the security and privacy issues arising from the widespread use of user data and AI technologies,” a press release from the company said.
The white paper also introduces new technologies that could help make 6G possible, including the use of the terahertz (THz) frequency band, novel antenna technologies to enhance the coverage of high frequency band signals, advanced duplex technologies, the evolution of network topology, spectrum sharing to increase the efficiency of frequency utilization and the use of AI in wireless communications.
