Chinese Researchers Develop 6G Chip That Covers The Entire Spectrum From 0.5 To 115 GHz, Reaching Speeds Over 100 Gbps And Smart Applications.
Chinese researchers announced the development of the world’s first full-frequency 6G chip. The device covers the entire range from 0.5 to 115 GHz and can achieve speeds over 100 gigabits per second, according to a report from the South China Morning Post (SCMP). The advancement promises to reduce digital inequality between urban and rural areas, providing continuous coverage across the wireless spectrum.
Compact And Innovative Chip
The team consists of scientists from Peking University and the City University of Hong Kong. They managed to integrate the entire spectrum into a chip the size of a fingernail, measuring just 11 mm by 1.7 mm. Previously, it would have been necessary to use nine different radio systems to achieve the same coverage.
The device combines millimeter waves and terahertz with microwaves of low frequency. This integration ensures a smooth exchange between long-range frequencies and ultra-high-speed applications.

“The development of 6G faces urgent challenges,” said Professor Wang Xingjun from Peking University, to China Science Daily. According to him, future networks need to leverage the advantages of all available frequency bands.
Diverse Frequencies And Applications
The highest frequencies offer great bandwidth and ultra-low latency, ideal for virtual reality and even remote surgeries. Lower bands ensure broad coverage, reaching remote areas, underwater environments, and even space.
In comparison, the average rural mobile phone speed in the United States hovers around just 20 megabits per second. Therefore, the performance leap of the chip is impressive.
Fusion Of Photonics And Electronics
To overcome the high costs of conventional systems, scientists turned to photonic-electronic fusion. The broadband electro-optical modulator converts wireless signals into optical ones. Then, photonic components process these signals, while transmission uses adjustable lasers.
The chip managed to maintain stability across the spectrum during testing. It also achieved frequency tuning of 6 GHz in just 180 microseconds, hundreds of times faster than the blink of an eye. The single-channel data rate exceeded 100 Gbps.
“The system generates communication signals quickly, accurately, and quietly at any frequency within 0.5 to 115 GHz,” reported the Guangming Daily.
Frequency Navigation
Another highlight is the so-called “frequency navigation.” If interference arises on one band, the system automatically switches to a free channel. Professor Wang Cheng from CityU compared the process to a driver smoothly changing lanes in traffic, ensuring continuous communication.
Ready For Artificial Intelligence
Professor Shu Haowen from Peking University explained that the device achieves a balance between size, energy consumption, and performance. This enables applications in crowded environments, such as stadiums and concerts, where thousands of devices compete for connection.
Moreover, Wang Xingjun emphasized that the chip paves the way for a hardware foundation for native artificial intelligence networks. He stated that the technology could dynamically adjust communication parameters through integrated algorithms, handling complex electromagnetic environments and performing real-time sensing.
Next Steps
The researchers are already working on creating plug-and-play modules, no larger than a USB drive. These devices can be integrated into smartphones, base stations, drones, and Internet of Things devices.
With this, the goal is to accelerate the arrival of flexible and intelligent 6G networks capable of meeting high-speed and broad coverage demands.
The complete study was published in the journal Nature.
