6G vision could occur as early as 2028-Samsung unveils 6G vision

Filed in Technology by on July 23, 2020 0 Comments

Samsung revealed in a report its 6G vision of the future, including technical and societal mega trends, new services, requirements, candidate technologies, and an expected timeline of standardisation.

6G COULD OCCUR AS EARLY AS 2028

Sunghyun Choi, head of Samsung’s Advanced Communications research centre said, “While 5G commercialisation is still in its initial stage, it is 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.”

In its report, Samsung predicted that earliest commercialisation of 6G could occur in 2028 with mass commercialisation taking place roughly two years after that.

HUGE PERFORMANCE LEAP

Samsung also sees the technology taking a huge performance leap over 5G networks, which are currently barely getting off the ground. Peak data rates for 6G will be 1000 gigabits per second, or about 50 times that of 5G.

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

PREDICTING CASE USAGE FOR 6G

The predication of case usage for 6G may however be a little premature.

Jason Leigh, a senior research analyst for mobility said, “It’s really hard to conceptualise what the use cases for 6G might be, when we’re still trying to figure out the use cases for 5G. Nevertheless, if 6G lives up to its speed and latency specs, it could be used in a variety of ways.”

Charles King, the principal analyst at a technology advisory firm said, “Features like these could support a wide range of advanced education, training and certification processes in various industries. They could also enhance remote support for healthcare and other hard to come by services for rural communities. There will also likely be numerous military applications, from advanced communications to real time battlefield analysis.”

WAVE TECHNOLOGY PROBLEMS

Because 6G will be operating in the terahertz bandwidth, it is expected to encounter problems similar to those currently facing 5G millimetre wave technology.

This is noted in the Samsung report: “To cope with the difficult propagation characteristics of THz band it may be natural to enhance the massive MIMO technology that was introduced to support millimetre wave band in 5G. Since the THz band requires much more antennas than the millimetre wave band, there may be significantly more practical difficulties.”

MIMO stands for multiple input, multiple output and is a way for multiplying the capacity of a radio link.

Initially wireless service providers will likely adopt the same phase in strategy they are using with their 5G transition when they introduce 6G. Early 6G phones will support 5G and 6G until the newer technology becomes global.

MORE CONNECTED DEVICES WITH 6G

Wireless service providers could have problems selling 6G to consumers if 5G is any indicator. The Samsung report noted that it’s expected that the number of connected devices will reach 500 billion by 2030.

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

The report noted machines will need to be connected by means of wireless communications. The connected machines will include vehicles, robots, drones, home appliances, displays, smart sensors installed in various infrastructures, construction machines and factory equipment.

The report also interestingly said: “As the number of connected machines grows exponentially, those machines will become dominant users of 6G communications. In 5G, machines were also considered in defining requirements and developing technologies. We expect new 6G technologies have to be developed specifically to connect hundreds of billions of machines taking into account what is required for machines.”
