Scientist develop
terahertz transmitter capable of sending data 10 times faster than 5G
Scientists from Japan have
developed terahertz (THz) transmitter technology, a next generation system
which can transmit digital data over 10 times faster than 5G mobile networks.
It will pave transmitting digital data at a rate exceeding 100 gigabits per second
(gbps) over a single channel using the 300-gigahertz band.
Scientists have developed a next

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 published a notice; 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.
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. Last year, the group demonstrated that the speed of a wireless link in the
300-GHz band could be greatly enhanced by using quadrature amplitude modulation
(QAM). This year, they showed six times higher per-channel data rate, exceeding
100 gigabits per second for the first time as an integrated-circuit-based
transmitter.
Important Feautre
