During that period, he led a project for the globally first large-scale implementation of over-the-air firmware update of mobile devices, FOTA, in cooperation with a Silicon Valley-based startup. He was also responsible for the corporate-wide standards strategy and drove global standard initiatives, e.g., as a member of the Board of Directors of CDMA Development Group (CDG) and WiMAX Forum, and as the Chair of 3GPP2.
Prior to that, he worked on the 3G CDMA commercial launch, leading to one of the first large-scale deployment of CDMA2000 1xEV-DO, an IP-centric and best-effort-based mobile data system, in the world. In the past, he played a leading role of the TDMA-based cellular mobile system standardisation and its commercial launch in Japan. He also engaged in the bidding for offshore spectrum auctions and succeeded in securing a license in Paraguay.
He started his professional career in 1977 as a mobile satellite system R&D engineer accomplishing the commercial system design and specification of the first global digital-based mobile satellite system standard named Inmarsat-M/B. He received a B.S. degree in Applied Physics, an M.S. degree in Physics and Dr. Engineering in Communications Science from Waseda University.
