Chinese researchers from Peking University and City University of Hong Kong have unveiled the world’s first “all-frequency” 6G chip, capable of ultra-high-speed mobile internet across the entire spectrum—ranging from 0.5 GHz to 115 GHz.
Traditionally, covering this wide frequency range required multiple radio systems.
The newly developed chip, however, consolidates millimeter-wave, terahertz, and low-band frequencies into a thumbnail-sized device (about 11mm × 1.7mm).
Its single-channel data rates exceed 100 Gbps, enabling lightning-fast tasks like downloading a 50 GB 8K movie in merely seconds.
Engineers achieved rapid frequency switching—within 180 microseconds—and integrated “frequency-navigation” features to automatically hop to cleaner channels when interference occurs.
Experts say this chip could dramatically narrow the digital divide.
Current rural broadband speeds in the U.S. average just 20 Mbps—rendering this 6G breakthrough potentially thousands of times faster.
This advancement also lays the hardware groundwork for AI-native networks that adapt communication parameters dynamically and sense environmental changes in real time.
The next goal for researchers is packaging this technology into plug-and-play modules—about the size of a USB stick—that can fit into smartphones, drones, IoT devices, and base stations.
