Tokushima Team Sets New 112‑Gbps Wireless Record

The team from Tokushima University has pushed the limits of wireless speed, achieving 112 gigabits per second in the 560‑gigahertz band using soliton microcombs. This breakthrough is not about faster phones for now; it tackles the hidden part of networks that moves data between base stations. Backhaul capacity can decide whether future 6G feels fast or stays stuck in congested pipes, making this result worth watching. The record relies on a frequency that goes beyond where usual electronics lose power and add noise. In the terahertz zone, past systems managed only a few to several dozen gigabits per second. Crossing 100 Gbps above 420 GHz puts the work into a more serious category for future networks.

Stability at these frequencies is as important as bandwidth. Phase noise and weak output power make signals fragile when trying to cram more data into a single channel. Tokushima’s system uses a small fiber‑coupled microresonator, cutting the need for exact optical alignment. Temperature control also keeps the resonance steady, turning a lab number into something that could run longer in real life. To bring this into everyday networks, researchers still need to reduce phase noise further, support higher‑order modulation, boost terahertz output power, and design better antennas for longer distances. The next step will bring the technology closer to practical use, but it won’t appear on a phone spec sheet anytime soon.
