The band, which sits between microwaves and visible light, . It can detect explosives, screen for cancer, produce super-high resolution images, and - best of all - move huge amounts of data very quickly.
In 2012, when 4G technology was only just arriving, scientists transfer rates of 3Gbps. In 2016, a team at the Tokyo Institute of Technology 34 Gbps. Now, however, engineers at Hiroshima University have built a terahertz transmitter capable of data transfer speeds exceeding 100 Gbps.
Ultra high speed
At that rate, a DVD would transfer in a fraction of a second. An HD movie wouldn't be much slower.
"But we are now approaching terabits per second using a plain simple single communication channel. Terahertz could offer ultrahigh-speed links to satellites, which can only be wireless. That could, in turn, significantly boost in-flight network connection speeds, for example."
Unfortunately, though, it's not yet possible to commercially exploit the technology - the band is only available for research purposes. But its future allocation at the 2019 World Radiocommunications Conference, so sit tight a few more years and blazing-fast wireless data transfer will be with us before you know it.
