Researchers have developed a terahertz transmitter, which delivers at least 10 times faster data transmission than 5G, and the technology is expected to be implemented in 2020.
A five day 2017 International Solid State Circuit Conference (ISSCC) was held in California, San Francisco, from February 5th to 9. Terahertz transmitters will be shown at this circuit conference, which can send all the contents of an DVD instantaneously. (editor's note: terahertz frequency is a new huge frequency resource, which is expected to be applied to ultra high speed wireless communication in the future)
Minoru Fujishima is a professor at Hiroshima University, Japan, and one of the terahertz researchers. He said: "terahertz can also be connected with satellites at ultra high speed, and the connection with satellites can only be done by wireless. It's also good for, for example, it greatly promotes the development of dynamic network connections. Other possible applications include fast downloading of resources to mobile devices, and ultra fast wireless connectivity between base stations."
It is understood that the research team developed a frequency transmitter from 290GHz to 315GHz, to achieve the speed of communication 105Gbps. Although this band has not yet been assigned, it is worth noting that it is in the range of 275GHz to 450GHz, which will be discussed at the 2019 World Radio Conference organized by the ITU radio communication department.
It is understood that last year, the R & D team has shown to the use of orthogonal amplitude modulation (QAM) significantly improve the 300GHz frequency wireless connection speed research results. This year, they show faster transmitters, with a single channel that is six times faster than before. As an integrated circuit transmitter, it achieves a single channel rate of more than 100 Gbps. for the first time
"This year, our newly developed launcher delivers ten times as much power as we did before. This makes it possible for a single channel data rate of 300GHz to exceed 100 Gbit/s." Fujishima says so.
He also said: "we usually discuss the wireless data transmission rate megabits per second or gigabits per second, but now we are closer to achieving the transmission rate of terabit per second using a single communication channel is simple."
Next, Hiroshima University, Japan's national information and communication research and Panasonic's research team plans to further develop 300GHz ultra high-speed wireless circuits.
