Free-space optical communications (FSOC), which use lasers for data transmission, are a promising approach for achieving high-speed links between aircraft, spacecraft, and ground stations. However, achieving 360-degree coverage requires multiple articulated terminals installed on the fuselage of aircraft, exceeding size, weight, and power limits....

A team of researchers from Universidad Carlos III de Madrid (UC3M) and Universidad Politécnica de Madrid (UPM) has developed an innovative algorithm for Wi‑Fi networks called "Ponte" that can provide communication in industrial environments with a level of reliability comparable to that of wired solutions. This advance will enable wireless...

A research team at the University of Ottawa has developed an advanced artificial intelligence system designed to autonomously defend wireless networks from jamming attacks, operating much like a digital immune system. This technology can automatically detect and respond to jamming in real time, which could play a critical role in...

Between 2016 and 2024 there were 193 internet shutdowns imposed in 41 African countries. This form of social control is a growing trend in the continent, according to a new open-access source book. It has provided the first-ever comparative analysis of how and why African states use blackouts—written by African...

In a disaster, there are often massive network outages. When the Ahr, a small river in Rhineland-Palatinate, burst its banks in July 2021, the entire telephone and mobile network quickly collapsed as the floodwaters and mud destroyed many exchanges. For emergencies like this, researchers at Fraunhofer FIT have developed smart...

The next generation of wireless communication will move into signal frequencies even higher than those of today's 5G systems, allowing signals to carry vastly more data at much higher speeds. These high-frequency bands, expected to underpin future 6G networks, could support data-hungry technologies such as untethered virtual reality headsets and...

Reconfigurable intelligent surfaces (RIS) are engineered structures comprised of several elements known as 'meta-atoms,' which can reshape and control electromagnetic waves in real-time. These surfaces could contribute to the further advancement of wireless communications and localization systems, as they could be used to reliably redirect, strengthen and suppress signals....
