India, June 11 -- Opening thoughts. A 6G milestone has been achieved in Japan, with researchers from the Tokushima University finding a way to transmit data at a speed of 112 gigabits per second, or Gbps. This breakthrough is built on a newly developed terahertz wireless communication system driven by micro-combs-special photonic devices fitted onto microchips that generate optical frequencies for wireless networks. Achieving such speeds, at a frequency above 420GHz for the first time to be specific, indicates a way to negate limitations that often plague signal power and noise at higher frequencies-and that means slower data transmission rates.

6G is being pieced together in many countries, including the US and Japan, with conversations...
