Japanese Researchers Achieve 112Gbps Wireless Speed at 560GHz

Researchers from Tokushima University, Tokyo University, and Gifu University have developed a TeraHertz Wireless Communication System that achieves record-breaking data transmission speeds. The system operates in the 560GHz band and successfully demonstrated wireless communication capabilities at unprecedented frequencies for this class of technology.

Record data transmission speed using microresonator frequency comb technology for future networks.

The prototype utilizes microresonator frequency comb technology to generate stable signals across high-frequency bands. Researchers achieved a data transmission speed of 84Gbps using QPSK modulation. They further increased performance to 112Gbps by switching to 16QAM modulation schemes. The system also operates effectively in the 350GHz band and above.

This achievement marks the first implementation of 100Gbps-class wireless communication above the 420GHz frequency range. The research team describes this development as a critical step toward realizing practical 6G wireless systems with ultra-high-speed mobile backhaul capabilities. The findings received peer review and were published in Nature following an October announcement.

The technology currently exists only as a laboratory prototype designed for small-scale demonstration purposes. Academic institutions have not disclosed specific commercial availability timelines or pricing details for this research hardware.

Researchers have not confirmed when the system will transition from experimental use to broader market deployment.
