Researchers at Japan's Tokushima University, the University of Tokyo, and Gifu University have developed a terahertz wireless communication system capable of transmitting data at 112Gbps in the 560GHz band. This is significantly faster than the data rates of a few gigabits per second typically achieved by conventional terahertz communication systems operating at similar frequencies.
The researchers said this is the first time any technology has achieved 100Gbps-class wireless communication beyond 420GHz, potentially opening a new frontier in high-frequency wireless communications and paving the way for 6G mobile networks, which promise ultra-high speeds, ultra-low latency and massive network capacity.
The discovery was initially announced last October before undergoing peer review and being published this week. in the scientific journal NatureIn the research paper, the study authors noted that the biggest obstacles to generating stable, high-quality signals beyond 350GHz are increased phase noise and reduced output power.
To overcome these limitations, the team combined microcombs coupled to high-order data modulation optical fibers to develop their new prototype. Microcombs – short for microresonator frequency combs – were chosen because they offer high frequency stability and low phase noise, making them ideal for transmitting reliable signals beyond 350GHz.
Microcombs are tiny photonic devices that act like optical rulers, splitting laser beams into a series of precise, evenly distributed, highly stable light frequencies. These extremely thin laser lines enable extremely high data rate transmission while minimizing phase noise, making microcombs suitable for terahertz communications.

Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
