TOKYO  - Japan is aiming to develop a super-fast wireless system by the 2020 Tokyo Games that would allow a smartphone user to download three high-definition movies in one second, an official said Friday. The technology, which is still in its early stages, would use wireless semiconductors, the official of the Internal Affairs and Communications Ministry told AFP. “The chips would use very high frequency bands, called terahertz signals, which could move data at a rate of 100 GB per second. And that would be as fast as downloading three movies in a second,” he said.

The ministry wants the technology in place in time for the Tokyo Olympics, he said, adding subcontractors would be recruited to take on the research.
