His summary of technological news, through the daily technical bulletin DGiT, for Tuesday, July 14.
1. 6G: 2028
This is expanding the boundaries of this newsletter, which gives you news and insights on technology that you can use, in theory. If there’s a takeaway, it’s 6G is coming in 2028. You can go ahead.
But if you want the details: Samsung has released some of the first widely published details on 6G, in a whitepaper. [PDF] Available now.
Yes, yes, we are still waiting for 5G in mid 2020But 6G isn’t just about the next speed barrier:
- “While 5G commercialization is still in its infancy, it is never too early to start preparing for 6G because it generally takes around 10 years from the start of research to the commercialization of a new generation of communications technology.” said Sunghyun Choi, director of the Advanced Communications Research Center.
- “Samsung defines three categories of requirements that must be met to perform 6G services: performance, architecture and reliability requirements.”
- The company will begin “full-scale” 6G research this year, Choi said, with the goal of starting work to define and develop technical standards in 2021.
Examples of Samsung-defined 6G performance requirements:
- A maximum data rate of 1,000 Gbps (gigabits per second)
- Air latency less than 100 microseconds (or 0.1 milliseconds)
- Which is equivalent to around 50 times the maximum data rate and a tenth of the latency of 5G, in an ideal world.
- Other requirements: double the energy efficiency of 4G and extreme reliability for near zero data errors (10 ^ -7)
- The following diagram compares the key performance requirements between 6G (darker blue) and 5G:
So how can 6G be used in the near future? 16K VR and holograms, of course:
- Samsung provides use cases for the technology, including truly immersive XR (AR / VR / Mixed Reality), jumping from current 4K technology to 16K VR streaming that requires downlink speeds of 0.9Gbps. Samsung notes that current 5G connections cannot provide this speed.
- Samsung says streaming AR to an 8K screen currently requires 55.3Mbps, and believes that “really immersive” AR requires speeds of 0.44Gbps.
- In high-fidelity holograms, Samsung suggests a hologram display on top of a 6.7-inch 11.1 gigapixel form factor mobile device display requiring ‘at least 0.58 Tbps’ data rates.
- Another angle is a ‘Digital Replica / Digital Twin’ technology, to replicate people, devices, places and more, which requires speeds of several Tbps, according to the firm.
- The idea of a large-scale digital hologram with a delay of 0.1 ms is not a bad one. And it probably would have been very helpful during COVID-19 crashes!
- Samsung is not alone in looking at 6G, but the detail here is significantly more than previous recognitions of 6G research from other gamers like Nokia and Ericsson.
- But this is the first time we’ve seen widely published tech specs, and a timeline other than ‘6G is ten years away.’
- I’m probably not going to remember if Samsung was right about 2028 in 2028, but it’s still important to have an idea of the future to come to shape your thoughts.
