Sony and Mitsui Succeed with World’s First Successful Operation of Standalone 5G Enabling Dynamic Spectrum Access System

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).
