With the aim of realizing an innovation hub that practices research on communications,
particularly the high-reliability of communications, which support the digital society,
our research center promotes leading research on system integrity based on hardware such as devices and systems,
and aims to conduct the research on the social implementation of the research results and the international rule-making technologies.
In the field of communications, in order to capture the international market, Open-Close strategy is required,
which considers standardizations, research and development in an integrated manner.
Our center started its activities as a research base that combines the function for standards development
and the test-house where performs standard conformity test,
and the function for research and development related to high-reliability of products.
Theme
At this research center, we conduct research on highly reliable communication technologies
necessary for autonomous driving and connectedness
which leads to "standards proposal" collaborating with companies and government,
and we will also be well-equipped with "test and consulting" environment for verifying the conforming to the standards.
Especially in terms of the hardware, we define the EMC at physical layer level, QoS over data link layer and
the security under the network layer as "three pillars of hardware reliabilities",
and aim at the proposal of wired communication (optical fiber and copper wire) with high resistance
and wireless communication systems, and the construction of the index and test methods of
"the System Integrity" for comprehensively evaluating them at the automotive environment.
