112 Gbps Wireless Transmission in 560 GHz Band Demonstrated for 6G

Researchers from the University of Tokushima and Gifu University have demonstrated wireless data transmission at 112 Gbps in the 560 GHz band. The achievement uses a micro-optical comb device with a fiber-coupled micro-resonator.

Researchers achieve 112 Gbps using 16QAM modulation.

The team achieved 84 Gbps using QPSK modulation and 112 Gbps using 16QAM modulation. This is the first demonstration of 100 Gbps-class wireless communication above 420 GHz, according to the research group.

Specifications

• Frequency band: 560 GHz
• Maximum data rate: 112 Gbps
• Modulation schemes: QPSK (84 Gbps), 16QAM (112 Gbps)
• Device type: Micro-optical comb with fiber-coupled micro-resonator

The technology is intended as a foundation for 6G ultra-high-speed mobile backhaul and optical-wireless convergence. The work was conducted by researchers at the two Japanese universities.

The researchers have not disclosed a timeline for commercial deployment or further testing.
