Scientists have developed a next-generation system that can transmit digital data more than Data speeds 10 times faster than 5G achieved by terahertz transmitter, a breakthrough that will pave the way for faster downloads and improve in-flight network speeds.
Researchers at Hiroshima University and the National Institute of Information and Communication Technologies in Japan have announced the development of a terahertz (THz) transmitter capable of transmitting digital data at speeds above 100 gigabits per second in a single channel using the band Of 300 gigahertz.
The THz band is a vast new frequency resource that is expected to be used for future ultra-high-speed wireless communications. The research group has developed a transmitter that achieves a communication speed of 105 gigabits per second using the frequency range 290 GHz to 315 GHz.
This frequency range is currently unassigned but is within the frequency range of 275 GHz to 450 GHz. Last year, the group demonstrated that the speed of a wireless link in the 300 GHz band could be improved by using the modulation of Quadrature amplitude (QAM). This year, they showed a six-fold higher data rate per channel, over 100 gigabits per second for the first time as an integrated circuit-based transmitter.
At this data rate, the entire contents of a DVD (digital versatile disc) can be transferred in a fraction of a second. “This year, we developed a transmitter with a transmission power 10 times higher than the previous version, which made the data rate per channel exceed 100 Gbit per second at 300 GHz,” said Minoru Fujishima, University of Hiroshima.
“We usually talk about wireless data rates in megabits per second or gigabits per second, but now we are approaching terabits per second using a simple simple communication channel,” Fujishima said. “Fiber has made high-speed cable connections, and wireless links are far behind,” he said. “Terahertz could offer ultra-high-speed links to satellites too, which can only be wireless, which could, in turn, significantly increase the speed of the in-flight network, for example,” added Fujishima.
“Other possible applications include the rapid download of content servers to mobile devices and ultra-fast wireless links between base stations,” he added. “Another completely new possibility offered by the wireless terahertz is the high data rate of minimal latency communications,” Fujishima said. “Optical fibers are made of glass and the speed of light decreases in the fibers, which makes optical fiber inadequate for applications that require real-time responses,” he said.
