Over the last decade, network engineers around the world have been getting excited about a part of the electromagnetic spectrum called the (opens in new tab).
The band, which sits between microwaves and visible light, (opens in new tab). 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 (opens in new tab) 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 (opens in new tab) 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.
