Never mind 5G, researchers have found something much faster

10 times faster than 5G

Japanese boffins have developed a terahertz (THz) transmitter capable of transmitting digital data at a rate 10 times or more faster than that offered by the fifth-generation mobile networks (5G).

5G is expected to appear around 2020 but a terahertz transmitter is much faster and sexier. It would mean that a complete DVD would be transferred in a fraction of a second.

According to the research scheduled to be presented at the International Solid-State Circuits Conference (ISSCC) the terahertz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications.

One of the researchers Minoru Fujishima, a professor at Hiroshima University in Japan, said his team managed to developed a transmitter that achieves a communication speed of 105 gigabits per second using the frequency range from 290 gigahertz (GHz) to 315 GHz.

He said that terahertz could offer ultrahigh-speed links to satellites as well, which can only be wireless. That could, in turn, significantly boost in-flight network connection speeds, for example. Other possible applications include fast download from contents servers to mobile devices and ultrafast wireless links between base stations.

This range of frequencies are currently unallocated but fall within the frequency range from 275 GHz to 450 GHz, whose usage is to be discussed at the World Radio communication Conference (WRC) 2019 under the International Telecommunication Union Radiocommunication Section (ITU-R).
