Terahertz Wireless is coming in future – up to 100Gbps transfer speed

by

When everyone thought the 5G mobile network is the future with up to 10Gbps transfer speed. Hiroshima University yesterday together with Panasonic and DICT announced the development of a terahertz (THz) transmitter. This new technology capable of transmitting digital data exceeding 100 gigabits per second on a single channel using the 300-GHz band. Theoretically it’s 10 times or could be even faster than the fifth-generation mobile networks (5G).

Prof. Minoru Fujishima from Hiroshima University said:

“We usually talk about wireless data rates in megabits per second or gigabits per second. But we are now approaching terabits per second using a plain simple single communication channel. Fiber optics realized ultrahigh-speed wired links, and wireless links have been left far behind. Terahertz Wireless could offer ultrahigh-speed links to satellites as well, which can only be wireless. Other possible applications include fast download from contents servers to mobile devices and ultrafast wireless links between base stations”

Last year, they demonstrated the wireless link in the 300-GHz band could be greatly enhance by using quadrature amplitude modulation (QAM). This year, they showed six times higher performance exceeding 100 gigabits per second. This is equal a whole content on a DVD (4.7GB) can be transferred in just a second. Terahertz Wireless was supported and as part of an R&D on Key Technology in Terahertz Frequency Bands of the Ministry of Internal Affairs and Communications, Japan.

Pokdepinion: The technology is very far away before adopted into a smartphone or a PC. The fully potential for this technology is on industrial or on the server side.
