Chinese Research Team Announces Chip for 6G, Covering 0.5G to 115GHz in a Single Chip

A research team from Peking University in China and City University of Hong Kong published the world's first "all-frequency capable" wireless chip in the British scientific journal Nature on August 27, 2025. It demonstrates transmission in excess of 100 Gbps per second over a single communication channel and shows the potential for utilizing the full spectrum in future 6G.

The newly developed chip is characterized by its small size (11 mm x 1.7 mm) and its ability to cover an extremely wide frequency range of 0.5 GHz to 115 GHz. The range that was previously handled by multiple separate radio systems can now be handled by a single chip as nine contiguous bands. The key is a method called "optoelectronic fusion," which combines the broadband and low-loss characteristics of light with the strengths of electronic circuits that excel in control and signal processing.

In their paper, the research team states, "Our system is a breakthrough step toward the realization of future all-frequency, all-situation wireless networks," and emphasizes their achievement, "This will enable wireless communications that can use a wider bandwidth, communicate faster, and switch between functions more flexibly than conventional methods. The company emphasized the achievement of the project.

The future of practical application and modularization in a variety of communication devices such as smartphones, base stations, and drones is expected to attract much attention in the 6G era.
