Sony and Mitsui jointly announced today that they have achieved the world’s first successful operation of Sony’s Dynamic Spectrum Access (DSA) technology in a standalone 5G environment. Along with this success, the two companies have signed a memorandum of understanding to enter a partnership to study the commercial potential for this technology and ways to use it to support effective use of spectrum resources.
Sony has built its track record by engaging in research and development of DSA technology since an early stage. In the world’s first case of large-scale practical implementation on the Citizens Broadband Radio Service (CBRS) system in the United States, Sony has been approved by the United States Federal Communications Commission (FCC) for commercial operation to provide spectrum management services (spectrum assignment, spectrum use authorization, operational parameter configuration such as maximum allowable transmission power) in the 3.5 GHz band (3GPP B48/n48).
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. Sony and Mitsui aim to build on these strengths to implement an effective spectrum utilization model and establish cutting-edge business and technology platforms to help achieve this goal across a broad geographic area, which includes not only Japan, the U.S. and Europe, but also Asia and other regions.
