Researchers in Japan have developed a system that can transmit digital data 10 times faster than 5G mobile networks.

Scientists from Hiroshima University and National Institute of Information and Communications Technology in Japan have reportedly developed a terahertz (THz) transmitter. The transmitter is capable of transmitting digital data at a rate exceeding 100 gigabits per second over a single channel using the 300-gigahertz band.

Important features:

  • The THz band is a new and vast frequency resource that is expected to be used for future ultrahigh-speed wireless communications
  • The transmitter developed by the researchers achieves a communication speed of 105 gigabits per second using the frequency range from 290 GHz to 315 GHz
  • This range of frequencies is currently unallocated but falls within the frequency range from 275 GHz to 450 GHz
  • In the year 2016, the group had demonstrated that the speed of a wireless link in the 300-GHz band could be greatly improved by using quadrature amplitude modulation (QAM)
  • This year, scientists showed a six times higher per-channel data rate, exceeding 100 gigabits per second for the first time as an integrated-circuit-based transmitter
  • The transmitter could be used to fast download from contents servers to mobile devices and ultrafast wireless links between base stations
  • Terahertz wireless also offers high-data-rate minimum-latency communications.
