Japanese telephone company Softbank announced the concept of “6G” and the challenges to achieve this concept.
Future 6G systems, which have yet to be standardized, are expected to bring new innovations, including increased reliability and energy efficiency, according to Asian operators. Softbank said it is trying to solve many problems in various areas in order to provide the necessary network infrastructure for society in the 6G era. To achieve this goal, SoftBank’s current efforts include evolving AI-powered network architectures and ensuring a high level of resiliency for all enterprises to take advantage of these advancements for purposes other than communication. This includes expansion into areas where wireless technology is available.
âMobile networks up to 4G were designed for use on smartphones. After 5G, with the advent of 6G, mobile networks will be transformed into a network infrastructure supporting digitization in all sectors. SoftBank Ryuji Wakikawa, Vice President and Head of Advanced Technologies, said:
âThe Internet is used to create a virtual digital space with a mobile network that connects base stations and devices. Thus, digital space and physical space are connected in real time. Use of AI. What is predicted and judged in virtual space is fed back into physical space with ultra-low latency. The 6G network not only functions as a communication network, but also evolves into a computer supporting the AI ââsociety. I’m going to go, âadded Mr. Wakikawa.
Executives also said cutting edge computing will be deployed across Japan and these computing locations will be capable of AI and other types of server processing. âThese computers establish a high-quality end-to-end communication environment that is networked in an advanced way. If AI sparks the next industrial revolution, 6G will be the communications infrastructure that enables it. To become.”
Softbank also said it has started research and development of potential 6G technologies such as: High Altitude Dock Station (HAPS) By piloting a base station in the stratosphere, the HAPS system can send and receive radio waves in areas up to 200 km in diameter and in the airspace above them. In this way, HAPS should be an important technology to extend the coverage of communication areas. We have successfully completed communication tests in the stratosphere, led the HAPS frequency band standardization initiative, and established a global industry alliance, âsaid Wakikawa. âIn addition, as part of our efforts to expand the use of frequencies, we are working on the terahertz range beyond millimeter waves and aim to apply these frequencies to telecommunications. Get faster communications than fiber optic cables. However, reaching speeds in excess of hundreds of gigabytes per second opens up new possibilities for wireless networks used in data centers, such as wireless communication between racks and servers. “
SoftBank also announced two initiatives as concrete examples of efforts to achieve 6G services. This first project is a research and development project which includes âmoving terahertzâ for smartphones. This initiative focuses on expanding the frequency range that allows SoftBank to use the terahertz band for mobile communications to provide commercial services.
The second is from Softbank Initiatives to establish HAPS technology, Exposed the communications equipment used in the stratospheric flight test. There will also be a demonstration of the cylindrical antenna and rotary connector technology currently under development. Both technologies are essential to realize the fingerprint fixation technology that controls the communication area required to provide stable communication services with HAPS.
