Is This the Wifi of the Future ? Researchers Transmit Wireless Data at 938 Gbps (New Record)

Researchers from University College London or UCL have just set a new record for wireless data transmission speed. In fact, they managed to transmit data at a speed of 938 Gb/s, which is close to a terabit per second. As the New Atlas website notes, the previous record was announced a few months ago by researchers from the Tokyo Institute of Technology, who had managed to achieve a speed of 640 Gb/s.

For comparison, the maximum speeds of 5G and Wi-Fi 7 are a few dozen Gbps. And, as UCL explains, the technology developed by its researchers is 9,380 times faster than the average speed of 5G in the UK. While it would take 19 minutes to download a two-hour 4K Ultra HD film with 5G at a speed of 100 Mbps, the technology developed by these researchers would allow this film to be downloaded in 0.12 seconds.

The combination of two technologies

Whether it’s 5G or Wi-Fi, current wireless networks operate at frequencies below 6 GHz. For their part, the UCL researchers transmitted data over a wider frequency range, from 5 GHz to 150 GHz. To do this, they used electronics, which are perfect for the range between 5 GHz and 50 GHz. But they also exploited a technology called “photonics” which uses light to generate radio information, and which is ideal for frequencies between 50 GHz and 150 GHz.

“Our solution is to exploit more of the available frequencies to increase bandwidth, while maintaining high signal quality and providing flexibility in accessing different frequency resources. This enables ultra-fast and reliable wireless networks, overcoming the speed bottleneck between user terminals and the Internet,” said Dr. Zhixin Liu, lead author of the study.

The Wi-Fi of the Future?

For now, this is just research. And it’s not certain that this technology will ever be standardized to be used on our routers and electronic devices. But in any case, researchers believe that it could be an alternative to Wi-Fi. But this connection could also be used to improve 5G, as well as the future 6G, to allow more people to use the network and avoid congestion.

After the laboratory tests, the next step will be to develop a prototype compatible with commercial tests. And if the commercial tests are conclusive, the technology could land on devices three to five years later. In essence, while the technology is promising, it still has a long way to go.

• UCL researchers manage to transmit data wirelessly at a speed of almost 1 terabit per second
• This would allow a 14 GB film to be downloaded in 0.12 seconds
• This feat was achieved by combining several technologies, which made it possible to exploit a wider frequency range, from 5 GHz to 150 GHz
• The next step will be the creation of a prototype for commercial testing
