</p><div id="story-body"><p class="story-body">Although many people have not yet thought about 5G mobile technology, Samsung has already started talking about 6G.

In a report released Tuesday, the South Korean electronics giant reveals its vision for the future of 6G, including technical and social megatrends, new services, requirements, candidate technologies and a timeline for standardization.

“While the commercialization of 5G is still in its infancy, it is never too early to start preparing for 6G because it typically takes about 10 years from the start of research to commercialization of a new generation of communication technology.” Sunghyun Choi, head of Samsung’s Advanced Communications Research Center, explained in a statement.

In its report, Samsung predicted that the first commercialization of 6G could already take place in 2028, with a mass commercialization taking place about two years later.

The groups of standards that develop protocols for mobile telecommunications, known as the Third Generation Partnership Project, or 3GPP, setting new standards around every decade or so, noted Kevin Krewell, a principal analyst in the San Jose, California offices Research Tirias, a high-tech research and consultancy company.

“Assuming there isn’t a big block on the committees, Samsung’s prediction seems right,” he told TechNewsWorld.

Leaving 5G in the dust

Samsung also sees technology making a leap forward in performance on 5G networks, which currently fail to take off. The peak data rate for 6G will be 1,000 gigabits per second, or about 50 times that of 5G, and air latency – the time between issuing an instruction and execution – of 100 microseconds or a tenth of 5G latency.

“The goals of 6G will be to take 5G to the next level of magnitude in terms of bandwidth and latency,” said Krewell.

“The overall goal is to make 6G connectivity even more reliable and robust than 5G by allowing for more connected services, such as connected radio drones and real-time augmented reality glasses,” he continued.

Reliability will be a delicate issue if 6G is used to control autonomous vehicles, notes Jack E. Gold, founder and chief analyst of J.Gold Associates, an IT consulting firm in Northborough, Massachusetts.
“The 6G will have to increase reliability because if you’re using things like autonomous vehicles, you can’t have signals that go away and cause car accidents,” he told TechNewsWorld.

In its report, Samsung said that 6G will be used for advanced services, such as immersive extended reality, high fidelity mobile hologram and the use of digital “twins” in virtual worlds.

Use cases

However, predicting use cases for 6G can be a little premature.

“It’s hard to know what technology will drive 6G adoption,” said Krewell. “In 2010, did we know that AR and VR, autonomous vehicles and drones would be at the top of our list of 5G uses?”

“It’s really hard to conceptualize what 6G use cases could be when we’re still trying to understand 5G use cases,” added Jason Leigh, senior research analyst for mobility at IDC, in Framingham, Massachusetts, a market research firm.

However, if the 6G lives up to its speed and latency specs, it could be used in a variety of ways.

“Features like these could support a wide range of advanced education, training and certification processes in various sectors,” said Charles King, the lead analyst at Pund-IT, a technology consulting firm in Hayward, California.

“They could also improve remote support for healthcare and other hard-to-find services for rural communities,” he told TechNewsWorld.

“Immersive applications for product and industrial design are likely,” he added. “There will likely also be numerous military applications, from advanced communications to real-time battlefield analysis.”

Propagation problems

Since 6G will operate in the terahertz bandwidth, it is expected that they will encounter problems similar to those currently facing 5G millimeter wave technology. This is recognized in the Samsung report.

“To cope with the difficult propagation characteristics of the THz band,” the report noted, “it may be natural to improve the massive MIMO technology introduced to support the millimeter wave band (mmWave) in 5G. Since the THz band requires many more antennas compared to the mmWave band, there may be significantly more practical difficulties. ” MIMO – multiple inputs, multiple outputs – is a way of multiplying the capacity of a radio link.

“The challenge with millimeter waves is that they can only travel three blocks and do not penetrate the doors very well,” Leigh told TechNewsWorld. “When you get to that level of terahertz, propagation problems multiply.”

Initially, wireless operators are likely to adopt the same stepwise strategy they are using with their 5G transition when introducing 6G. The first 6G phones will support 5G and 6G until new technology becomes ubiquitous.

“Take the best of what is already available and use it to take you to the next step,” explained Gold. “In the end, go to the next step and get rid of the older things.”

More cars than people

If 5G is an indicator, couriers may have trouble selling 6G to consumers.

“Selling to consumers seems confusing,” said King. “That is, unless suppliers present completely new types of devices and form factors.”

Companies that could use 6G’s features and functions to improve efficiency, reduce costs or create new market opportunities seem the most likely targets,” he added.

However, consumers may not play as important a role in adopting 6G as they have in the past in new generation implementations.

The Samsung report noted that the number of connected devices is expected to reach 500 billion by 2030, which is approximately 59 times larger than the world’s expected population of 8.5 billion at the time.

Mobile devices will take on various form factors, he continued, such as augmented reality glasses, virtual reality headsets and hologram devices.

Increasingly, he noted, machines will need to be connected via wireless communications. Such connected machines will include vehicles, robots, drones, household appliances, displays, smart sensors installed in various infrastructures, construction machines and factory equipment.

“As the number of connected machines increases exponentially, they will become dominant users of 6G communications,” said the report.

“Looking back on the history of wireless communications, technologies have been developed by taking on services for humans as the main driving applications,” he continued. “In 5G, machines were also considered in defining requirements and developing technologies.”

“We expect new 6G technologies to be developed specifically to connect hundreds of billions of machines taking into account what is needed for machines,” he predicted.
