Sony Group and Mitsui jointly announced that that they have achieved what they claim is the world’s first successful operation of Sony’s Dynamic Spectrum Access (DSA) technology in a standalone 5G environment.
Technological innovations such as Wi-Fi and 5G have allowed for ever-growing wireless use in industrial applications, resulting in an explosive increase in data traffic. On the other hand, spectrum (radio frequency) resources are limited, and the strain on these resources is becoming an issue. DSA technology is expected to help solve this problem by helping to optimize the use of radio frequency resources. It provides for centralized management of radio frequencies via a real-time resource management database, replacing the traditional method of managing each frequency band separately. This allows spatio-temporally underutilized spectrum to be allocated for use by new operators and users, while protecting incumbent operator networks and their users from harmful interference.
Practical implementation of DSA technology is already under way in Europe and the United States, with spectrum assignment for 4G/5G in certain regions and locations, along with infrastructure development, making it a growing global trend.
Accompanying this kind of diversification occurring in radio frequency resource assignment methods, new use cases and innovation in various industry applications, as well as automated spectrum management using DSA technology, are also being explored, leading Sony and Mitsui to join forces in looking into the commercial potential.
Mitsui is involved in a wide range of industrial domains, employing a multifaceted business approach, including building social infrastructure that uses ICT to drive smart transformation of cities and building sustainable infrastructure to improve quality of life in Asian and other developing nations. Also, through its subsidiary, Mitsui Knowledge Industry Co. Ltd. (MKI), the company is driving the use of “Local 5G,” an advanced scheme for implementing local 5G networks in Japan, in view of the growing need for wireless usage in industrial applications.
