Mobile wireless communication technology is one of the significant communication technologies that support the ICT society, connected with the high-speed backbone network using optical fiber. Evolution of the mobile wireless communication technology in Japan is indispensable to keep the leadership in this technology area in the world.
With the partnership of Japanese major mobile wireless manufacturers and Japanese Type I carrier, the mobile wireless technology group of the IT-21 center has been proposing the concept of “Dependable Air,” which is a heterogeneous and highly-reliable wireless network. The Dependable Air is able to work even in the event of a big disaster.
As a result, so far, (1) 5GHz-band 324Mbit/s wireless LAN terminal, (2) ultra-small size 3D system-in-package (SiP) millimeter wave wireless terminal for uncompressed high definition television (HDTV) transmission have been successfully developed, and (3) seamless handover technology for wide area broadband mobile wireless access (MBWA) and seamless system handover technology between MBWA and wireless LAN have been successfully demonstrated by field tests. Moreover, the Dependable Air with satellite communication systems such as Quasi-Zenith Satellite System (QZSS) has been proposed for improvement of dependability of wireless network.
In FY2019, the mobile wireless technology group was renamed to Wireless ICT Platform Project in Industry-Academia-Governmental-Collaboration Research and Development Division. From then, the project group started wireless IoT R&D projects and successfully developed a novel wide-band real-time spectrum monitor. In FY2022, the group has launched 3 new Industry-academia collaboration R&D projects related to wireless IoT and low earth orbit (LEO) Constellation Satellite communication for B5G era. In addition, the group would like to contribute to the local industries in Tohoku area including the establishment of venture companies based on our developments.
