A team from EEE has achieved a new world record in wireless transmission, reaching speeds of 938 Gb/s over a frequency range of 5-150 GHz. This speed is nearly 9,400 times faster than the average 5G download speed in the UK. The record-breaking result was made possible by combining radio and optical technologies, marking a first in wireless communication research.
Dr Zhixin Liu, the lead author of the paper, highlighted the importance of this innovation.
Current wireless systems are struggling to meet the growing demand for high-speed data. By using a broader range of frequencies, we’ve not only increased bandwidth but also ensured high signal quality, enabling ultra-fast and reliable networks."
Prof Izzat Darwazeh, co-author and director of UCL’s Institute of Communications and Connected Systems, emphasised the flexibility of this new technology.
Wireless technology offers unique versatility, especially in environments where optical cabling is impractical, such as factories with complex layouts. This breakthrough brings wireless communication up to par with recent advances in optical systems, crucial for next-generation networks.
Prof Polina Bayvel, co-director of the Institute and Head of the UCL Optical Networks Group, underscored the significance of the work.
This project reflects the UK’s leadership in advanced wireless and optical technologies. The infrastructure we’ve developed will be pivotal for the future of national communications, with major implications for everything from mobile connectivity to industrial applications.
The innovative system combines high-speed electronics, operating in the 5-50 GHz range, with light-based radio signal generation, performing in the 50-150 GHz range. This combination has the potential to dramatically enhance mobile internet speeds and wireless connectivity in dense urban areas, public spaces, and even large events like concerts.
As this technology moves towards commercialisation, it promises to significantly improve wireless communication in everyday settings, providing unprecedented speed and stability.
