Scientists develop the world's first 6G chip

6G technology is the successor to 5G and promises to bring about a massive leap in how we communicate. It will offer benefits such as ultra-high-speed connectivity, ultra-low latency and AI integration that can manage and optimize networks in real-time. To achieve this, 6G networks will need to operate across a range of frequencies, from standard microwaves to much higher frequency terahertz waves. Current 5G technology utilizes a limited set of radio frequencies, similar to those used in previous generations of wireless technologies.

The chip also employs an innovative method for generating and transmitting signals. First, a broadband electro-optic modulator converts wireless signals into optical ones, which are then passed through optoelectronic oscillators to generate the required radio frequencies. The oscillators utilize light and electricity to create stable, clean signals spanning from microwaves to terahertz waves. In tests, the system achieved 6 GHz frequency tuning in 180 microseconds, much faster than current technology.
