Li-Fi (Light Fidelity) is a wireless communication technology that utilizes the visible light spectrum (400–800 THz), similar to LED light, offering speeds up to 100 times faster than existing Wi-Fi (up to 224 Gbps). While it has fewer limitations in available frequency allocation and less radio interference, it is relatively... Read more

From smart grids to the internet of things, the modern world is increasingly reliant on connectivity between electronic devices. Thanks to University of Ottawa researchers, these devices can now be simultaneously connected and powered with a simple optical fiber over long distances, even in the harshest environments....

MIT researchers have designed a compact, low-power receiver for 5G-compatible smart devices that is about 30 times more resilient to a certain type of interference than some traditional wireless receivers.... Read more

As more connected devices demand an increasing amount of bandwidth for tasks like teleworking and cloud computing, it will become extremely challenging to manage the finite amount of wireless spectrum available for all users to share.... Read more

Connectivity is no longer a luxury—it is the backbone of how we live, work and move through the world. From smart homes to wearable tech, we rely on strong, seamless wireless networks. But with traditional radio frequency systems like Wi-Fi and Bluetooth reaching their limits in spectrum and precision, it... Read more

Self-driving cars which eliminate traffic jams, getting a health care diagnosis instantly without leaving your home, or feeling the touch of loved ones based across the continent may sound like the stuff of science fiction.... Read more

The evolution of wireless communications and the miniaturization of electrical circuits have fundamentally reshaped our lives and the digital landscape. However, as we push toward higher-frequency communications in an increasingly connected world, engineers face growing challenges from multipath propagation—a phenomenon where the same radio signal reaches receiving antennas through multiple...

When it comes to upgrading electrical and broadband infrastructure, new research from the University of Massachusetts Amherst shows that a "dig once" approach is nearly 40% more cost effective than replacing them separately.... Read more

Researchers have developed a new type of optical receiver, able to restore chaotic signals in free-space optical communication links distorted by atmospheric turbulence. Using a system of optical antennas integrated into a programmable photonic chip, the receiver can adapt in real time, maintaining the integrity of the signal even in... Read more

There's a major difference between humans and current artificial intelligence (AI) capabilities: common sense. According to a new paper by Walid Saad, professor in the College of Engineering and the Next-G Wireless Lead at the Virginia Tech Innovation Campus, a true revolution in wireless technologies is only possible through endowing...

Plasmonic modulators are tiny components that convert electrical signals into optical signals in order to transport them through optical fibers. A modulator of this kind had never managed to transmit data at a frequency of over a terahertz (over a trillion oscillations per second).... Read more

Modern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances without losing information.... Read more

Researchers at the University of Twente, in collaboration with the City University of Hong Kong, have designed a cutting-edge programmable photonic chip in a thin-film lithium niobate platform, an important material in photonics. Published in Nature Communications, this work paves the way for next-generation high-performance radar and communication applications.... Read more

Programmable metasurfaces (PMs), also sometimes referred to as reconfigurable intelligence surfaces, are smart surfaces that reflect wireless signals, but can also dynamically manipulate electromagnetic waves in real-time. These surfaces are highly advantageous for the development of many cutting-edge technologies, including advanced sensing and wireless communication systems.... Read more

Wireless connections are common in most households today. From your lights to your heating, everything can be connected and controlled through Wi-Fi. However, wireless technology is inherently vulnerable to the threat of jamming.... Read more
