As demand for lightning-fast, ultra-reliable wireless connectivity continues to surge, researchers are racing to lay the groundwork for the next generation of communications: 6G.
However, current materials face significant limitations, especially in the higher frequency bands that 6G networks will require. Now, a pioneering £1.4 million project led by the University of Glasgow’s James Watt School of Engineering, in partnership with Ireland’s Tyndall National Institute, aims to solve this challenge.
The AR-COM initiative (Active, intelligent Reconfigurable surfaces for 6G wireless COMmunications) will develop advanced “smart surfaces” to enable 6G performance breakthroughs.
“With AR-COM, we’re building on the expertise of Glasgow and Tyndall with industry partners to develop truly next-generation technologies,” said project lead Professor Qammer Abbasi. “Current wireless materials face major limitations at 6G’s higher frequencies. Intelligent reconfigurable surfaces could be key to delivering the robust networks and applications of the future.”
These intelligent reconfigurable surfaces (IRS) are engineered materials that actively guide wireless signals to devices, dramatically boosting signal strength and quality.
Over the next three years, the AR-COM team will design IRS using novel approaches like transition metal oxides and resonant tunnelling diodes to achieve unparalleled performance in 6G’s target millimetre wave and terahertz spectrum bands.
How Intelligent Surfaces Work With 6G
Today’s 5G networks utilize higher frequencies than previous generations to achieve faster speeds. However, 6G will go even further, tapping into the millimetre wave (30-300 GHz) and terahertz (0.1-10 THz) spectrum. At these frequencies, signals are easily disrupted and can struggle to penetrate obstacles.
That’s where intelligent surfaces come in. Embedded with tunable elements like special oxides or diodes, these materials can be programmed to shape and steer wireless beams dynamically.
When an IRS detects a weak signal, it manipulates the signal’s electromagnetic properties to redirect and amplify it toward the target device.
Intelligent surfaces offer several transformative benefits for wireless communications. They enable stronger, faster, and more reliable connections while significantly improving indoor coverage by eliminating traditional dead zones where signals struggle to reach.
In the future, these surfaces could play a crucial role in supporting emerging 6G applications, including augmented and virtual reality experiences, advanced robotics, and holographic communications. They could also contribute to environmental sustainability through their ultra-low power consumption, helping create greener network infrastructure. These capabilities work together to create a more robust and efficient wireless ecosystem.
By precisely controlling waves in real-time, intelligent surfaces effectively make the environment itself part of the wireless network.
The idea is that wherever they are installed, from building interiors to busy urban corridors, they can create invisible but powerful pathways for 6G signals to flow unimpeded.
According to Professor Muhammad Imran, head of the James Watt School of Engineering, the potential impact is immense. “Intelligent surfaces will be pivotal in delivering the ultra-fast, ultra-reliable, low-latency 6G connectivity to catalyze entirely new forms of communications and digital experiences,” he said. “They will transform how we interact with technology and each other.”
The AR-COM project, supported by UKRI, EPSRC, and telecom industry leaders, will culminate in a fully functional IRS prototype showcasing the ability to manipulate 6G signals with minimal latency or loss. It could pave the way for mass production and deployment of intelligent surfaces as a core 6G infrastructure.
Dr. Senad Bulja from Tyndall emphasized the importance of AR-COM’s innovations. “By creating surfaces that can dynamically redirect and amplify signals with ultra-low power usage, we can overcome the current limitations of IRS tech,” he explained. “This will enable a wealth of 6G use cases across devices and applications.”
Some of those future 6G applications could include immersive extended reality telepresence, real-time holographic displays, collaborative robotics, advanced wearables, and innovative city ecosystems. 6G’s convergence of communications and sensing may enable ‘Internet of Senses’ capabilities like haptic feedback and digital scent.
However, achieving the 6G vision will require continued breakthroughs in materials science, signal processing, and network architecture. Projects like AR-COM are a single stepping stone to experimenting with and solidifying the technologies underpinning next-gen connectivity.
With this focus on accelerating intelligent surfaces from lab to reality and as current 5G adoption hits its stride, we are optimistic for a seamless transition to a transformative 6G era in the not-so-distant future.
