Researchers Hit Terahertz Speed A team of developers from Hiroshima University, the National Institute of Information and Communications Technology and Panasonic has developed a terahertz transmitter that can send digital data at more than 100 gigabits per second over one channel. The technology, which operates in the 300GHz band, sends data ten times faster than 5G, according to the developers. The transmitter can hit 105Gbps on currently unallocated spectrums 290GHz to 315GHz, they said. (See Research Nudges Terabit Wireless Speeds, but What's the Range?) In 2016, the team used quadrature amplitude modulation to improve speed in the 300GHz range. This year's advance features an increased per-channel data rate six times higher than before. In other words, DVD content could transfer in fractions of a second, researchers said. "Fiber optics realized ultrahigh-speed wired links and wireless links have been left far behind," said Professor Minoru Fujishima of the Graduate School of Advanced Sciences of Matter at Hiroshima University in a statement. Terahertz wireless could deliver light-speed minimum-latency links that support fiber-optic data rates, he added. This afternoon, researchers from the trio will present their findings at the International Solid-State Circuits Conference, ISSCC 2017, in San Francisco. Related posts:
