What is Terahertz?
The ‘terahertz gap’ – where until recently bright sources of light and sensitive means of detection did not exist – encompasses frequencies invisible to the naked eye in the electromagnetic spectrum, lying between microwave and infrared in the range from 0.3 to 3THz. Terahertz radiation, also known as t-rays, has wavelength of 3-100 cm-1v.
Terahertz 10 times faster data speed than 5G
Transfer the whole content on a DVD in a fraction of a second.The THz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications. The research group has developed a transmitter that achieves a communication speed of 105 gigabits per second using the frequency range from 290 GHz to 315 GHz.This range of frequencies are currently unallocated but fall within the frequency range from 275 GHz to 450 GHz,
Scientists have developed a next generation system which can transmit digital data over 10 times faster than 5G mobile networks, an advance that will pave the way for faster downloads and improve in-flight network connection speeds.
Researchers from Hiroshima University and National Institute of Information and Communications Technology in Japan have announced the development of a Terahertz (THz) transmitter capable of transmitting digital data at a rate exceeding 100 gigabits per second over a single channel using the 300-gigahertz band.
“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,” Fujishima added.
