China unveils 'world first' 6G photonics chip claiming 100 Gbps speeds
Chinese
researchers have developed the world’s first multi-purpose 6G chip spanning a
complete range of wireless frequencies, with claims that it is capable of
mobile speeds of more than 100 Gbps.
The design uses
photonic-electronic fusion, converting wireless to optical signals and
processing them via photonics for speed and efficiency.
According to the
development team at Peking University and City University of Hong Kong, the
chip integrates the entire wireless spectrum (0.5–115 GHz) into a
thumbnail-sized device measuring 11mm × 1.7mm.
The chip combines
millimetre-wave, terahertz, and low-frequency microwave bands, enabling
seamless switching between bands for both remote coverage and high-speed
applications.
The developers say the chip can achieve a single-channel rate
over 100 Gbps, orders of magnitude faster than the most powerful 5G devices.
A
major feature of the new chip is frequency navigation, which enables it to
automatically switch to clear channels when interference occurs.
In
addition, the chip offers multipurpose programmability and dynamic frequency
adjustment, balancing size, power, and performance, which the developers say
makes it ideal for crowded environments.
The
developers say the new device establishes the first hardware base for AI-native
networks, enabling real-time environmental sensing and adaptive communication.
Researchers
eventually plan to produce plug-and-play USB-sized 6G modules for use in
smartphones, base stations, drones, and IoT devices.
