China Pioneers Unified 2G to 6G Network Technology Using Integrated Photonics

A Chinese research team from Peking University's School of Electronics has achieved a significant milestone by creating a wireless communication technology that supports 2G, 3G, 4G, 5G, and 6G networks on one integrated platform. This innovation, recently detailed in Nature Photonics, represents a shift away from the traditional stacking of frequency-specific hardware. The platform allows for base station miniaturization while slashing power consumption by more than tenfold.

Current telecommunications infrastructure is burdened by hardware redundancy, as each network generation requires its own dedicated equipment. This approach leads to high energy costs and complex physical installations on towers. By unifying these network lanes into a single road, the researchers have simplified the architecture required for global connectivity and reduced the physical footprint of future base stations.

The breakthrough utilizes integrated photonics, which employs light as the medium for signal modulation rather than traditional electronic oscillators. This system uses a microcomb-synchronized optoelectronic design to generate over 60 reconfigurable microwave frequencies. By pushing clock speeds beyond the 100 GHz threshold, the chip significantly outperforms the processing speeds of standard central processing units.

During experimental testing, the integrated system demonstrated transmission speeds 30 times faster than those found in conventional 6G approaches. It also supports complex modulation formats like 256-QAM, ensuring high data capacity alongside centimeter-level perception accuracy. This dual capability allows the device to handle both communication and sensing tasks simultaneously without signal degradation.

This technology is expected to provide the essential hardware foundation for latency-sensitive applications like satellite communications and embodied intelligence. It offers a scalable solution for the Internet of Everything, bridging the gap between centralized computing power and terminal devices. Industries such as autonomous driving and aerospace are likely to be the first to adopt these high-speed, low-power modules for real-time data processing.
