Chinese scientists are making progress in research on ultra-broadband 6G communication.
Researchers have developed an ultra-wideband system capable of high-speed wireless transmissions with adjustable frequency.
247 Peking University (PKU) stated that Chinese scientists have registered new advances in integrated ultra-wideband photonic-electronic technology for 6G wireless communication.
According to information published in the ChinaDailyA team from PKU and City University of Hong Kong has developed an ultra-wideband system capable of high-speed wireless transmissions with adjustable frequency, a world first.
The system can achieve wireless transmission rates exceeding 100 Gbps, enough to transmit 1.000 simultaneous videos in ultra-high-definition 8K resolution. As the next generation of wireless communication, 6G requires high-speed transmissions across different frequency bands.
But conventional electronic hardware is typically limited to certain frequency ranges due to differences in design, structure, and materials, which hinders operation across multiple bands or the entire spectrum.
To overcome this challenge, the team dedicated four years to developing an integrated ultra-wideband photonic-electronic system that supports high-speed transmissions at any frequency between 0,5 GHz and 115 GHz.
The innovation also features flexible adjustment, allowing for dynamic frequency switching in case of interference.
“This technology is like building a super-wide highway, where the electronic signals are vehicles and the frequency bands are lanes,” pointed out Wang Xingjun, vice-director of the School of Electronics at PKU. “Previously, the signals were concentrated in one or two lanes, but now there are many available. If one lane is blocked, the signals can flexibly switch to another, ensuring faster and more stable communication.”
