Sonas is a venture company originating from the University of Tokyo, with its core technology being the independently developed IoT wireless system "UNISONet." UNISONet is the world's first wireless technology to successfully apply industrial use through an innovative transmission method called "simultaneous transmission flooding." By making IoT "easy," UNISONet dramatically accelerates its social implementation, overcoming the challenges that have significantly limited its application areas. The name "Sonas" is derived from the phrase meaning "to lay the foundation." Sonas's mission is to enable various industries to benefit from IoT as a matter of course, thereby propelling society forward.
