Toyota Motor Corp. and the Japanese telecom company Nippon Telegraph and Telephone Corp. (NTT) are investing 500 billion yen ($3.26 billion) in artificial intelligence research and development to create advanced software aimed at making autonomous driving safer.

Nippon Telegraph and Telephone Corporation (NTT) in Japan has successfully demonstrated the world's first 100Gbps wireless transmission, using a new technology that already surpasses the upcoming 5G standard. But this new tech, called Orbital Angular Momentum (OAM) multiplexing, isn't likely to roll out on a large scale before 2030.
