A team of scientists has unlocked the potential of 6G communications with a new polarization multiplexer. Terahertz communications represent the next frontier in wireless technology, promising data transmission rates far exceeding current systems.... Read more

Wireless internet supports the daily activities of countless people worldwide, ranging from their professional communications to internet browsing and the streaming of movies or TV series. This spiking demand for wireless internet access goes hand in hand with greater power consumption, which in turn contributes to carbon emissions worldwide.... Read more

Radiofrequency (RF) switches are electronic components that control the routing of RF signals between different segments of circuits, for instance turning the signals on and off or redirecting them. These switches are central to the functioning of numerous communication technologies, including smartphones, cell towers, and wireless networks.... Read more

Computer science researchers have developed a new method for predicting what data wireless computing users will need before they need it, making wireless networks faster and more reliable. The new method makes use of a technique called a "digital twin," which effectively clones the network it is supporting.... Read more

Microsoft users worldwide, including banks and airlines, reported widespread outages on Friday, hours after the technology company said it was gradually fixing an issue affecting access to Microsoft 365 apps and services.... Read more

A method to analytically express the performance of wireless communication systems when using reconfigurable intelligent surfaces (RIS) has been successfully developed by researchers at Tohoku University, the University of Surrey, and the University of Nottingham.... Read more

UAB (University of Barcelona) researchers were involved in the development of a switch, an essential device in telecommunications, capable of operating at very high frequency with lower power consumption than conventional technologies. The technology has applications in the new 6G mass communication systems and is more sustainable in terms of... Read more

Researchers from the Smart and Wireless Applications and Technologies Group (SWAT-UGR) have conducted two scientific studies aimed at answering a common question: understanding how electromagnetic waves propagate in the medium.... Read more

The growing prevalence of high-speed wireless communication devices, from 5G mobile phones to sensors for autonomous vehicles, is leading to increasingly crowded airwaves. This makes the ability to block interfering signals that can hamper device performance an even more important—and more challenging—problem.... Read more

In April 2019, South Korea ambitiously launched the world's first 5G mobile communication service. While 5G in the 3.5 GHz band was commercialized, the communication quality did not meet consumer expectations. The installation of base stations in the 28 GHz band, which would provide true 5G service, was slow due... Read more

Florida Atlantic Center for Connected Autonomy and Artificial Intelligence (CA-AI.fau.edu) researchers have "cracked the code" on interference when machines need to talk with each other—and people.... Read more

A research team led by Rice University's Edward Knightly has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street....
