Breaking away from best effort The apps we currently offer have caused delays and packet loss when browsing the Internet and streaming videos. In order to build social infrastructure for industries that are expected in 6G, it will be equipped with distributed processing (mobile edge computing, MEC) and network resource division functions used in IoT terminals for mobile lines. Mobile networks have evolved beyond being closed and globally standardized, as opposed to the Internet, where mobile web systems and protocols have continued to improve over the years. In the future, in order to expand the range of services, we will change to a flexible structure and incorporate the structure of Internet services to realize convenient service provision. AI network We will utilize AI technology that is being used not only for image and voice recognition but also for network optimization and operation automation, and technology for virtualizing network devices including wireless base stations on a PC. By processing both GPU-processed software on PCs distributed on a mobile network, it is possible to provide high-quality networks and services at low cost. Area 100% 6G will utilize network technology utilizing the stratospheric platform (HAPS), low earth orbit (LEO) satellites, and geostationary (GEO) satellites to make the entire earth a communication area. As a result, it will provide services at sea, in the mountains, and in the air where base stations could not be maintained, and will support new industries such as autonomous driving, drones, and “flying taxis.” Area expansion In addition to HAPS developed by Softbank’s subsidiary HAPS Mobile, we will aim for commercialization based on the data obtained from the unmanned aerial vehicle “Sunglider” that succeeded in flying in the stratosphere and LTE communication in 2020. We will proceed with the development of aircraft and radios, and the maintenance of regulations. Frequency expansion In order to achieve 10 times the speed of 5G with 6G, we will utilize “terahertz waves” (100GHz to 10THz), which have a higher frequency than the millimeter waves used in 5G. At the World Radiocommunication Conference in 2019, a total of 137GHz was specified as a communication application, and by utilizing these for mobile communication, even higher speed and large capacity communication will be realized. Sensing by radio waves The radio waves that have been used for conventional communication are used to identify the position of people indoors, and Bluetooth is used to track location information. Develop a service that can simultaneously communicate, detect, and track with 6G radio waves. Charging and power supply by radio waves Solves the problem of distance, which is a disadvantage of Qi standard non-contact charging technology. We will develop a technology that can charge and supply power even when the distance is long by using radio waves, eliminating battery replacement and daily charging time. Frequency The frequency assigned on the assumption that each operator will occupy and use it will be able to share the vacant band among multiple operators by applying IP technology. We will develop “Massive MIMO” that allocates dedicated radio waves to individuals and “DSS (Dynamic Spectrum Sharing)” that mixes 5G signals with 4G radio waves to promote effective use of frequencies. When an ultra-secure quantum computer is put into practical use, it is possible that the RSA encryption, which is an Internet encryption technology, can be decrypted and the communication contents may be stolen. As a countermeasure against this, we will work on technology verification such as quantum cryptography (PQC) and quantum cryptography communication (QKD) to realize a secure network. Fault tolerance In order to maintain the mobile network, which is strengthening its role as a social infrastructure, even if a communication failure occurs, the conventional communication structure will be reviewed. Net Zero It is said that it can greatly contribute to the achievement of “Net Zero” by monitoring CO2 emissions with data from a large amount of sensors and terminals and reducing greenhouse gas emissions to virtually zero. In addition to handling privacy information and resolving issues related to information security, nighttime use of electricity charged during the day and real-time control of the base station according to the amount of communication are performed with the aim of making the base station carbon-neutral, minimizing power consumption. To become. 6G is expected to innovate by further enhancing the features of 5G, such as ultra-high speed, ultra-low latency, and multiple simultaneous connections, and improving reliability and energy efficiency. Softbank will expand the range of utilization toward 6G social infrastructure, and will contribute to strengthening fault tolerance and controlling CO2 emissions.
