Scientists in China and the U.S. have developed a tiny 6G chip that could make slow and unreliable data speeds in the countryside a thing of the past — and it’s hundreds of times faster than your smartphone’s current download speeds.
5G is the current gold standard for wireless communications, and it typically uses frequencies below 6 gigahertz, although this varies from country to country. The top-performing cellular network in the US in the first half of 2025 offered a 5G download speed of 299.36 megabits per seconds.
On the other hand, 6G, which experts say will be ready in 2030, is expected to use multiple frequency bands and has the potential to be 10,000 times faster than 5G. The trouble with tapping into 6G, however, is that devices will need multiple components to tap into the different radio-frequency bands — something that modern devices lack.
But now, researchers have integrated the entire wireless spectrum covering nine radio-frequency (RF) bands — from 0.5 to 110 GHz — into a chip measuring just 0.07 by 0.43 inches (1.7 by 11 millimeters).
The new chip is also capable of achieving a data transmission rate of more than 100 gigabits per second, including on low bands used in rural areas, where speeds can be notoriously slow. Communication also remained stable across the entire spectrum, the researchers found. They revealed their research in a study published Aug. 27 in the journal Nature.
To put this data speed into context, 1,000 smartphones embedded with the chip could stream an 8K ultra-high-definition video simultaneously without weaker performance, according to Chinese state media Xinhua.

This “one-size-fits-all hardware solution,” as the scientists described it in the study, could be reconfigured dynamically to switch the frequency band depending on when this is required.
This is important because devices tapping into 6G are going to utilize different wireless spectra — from microwave, millimeter wave (mmWave) to terahertz (THz) bands — the researchers noted.
High-frequency mmWave and sub-THz bands — between 100 GHz and 300 GHz — will be used for applications that require extremely low latency, such as high-speed artificial intelligence (AI) computing and remote sensing. But sub-6 GHz and microwave bands are still needed to provide coverage…
