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, […]
Global mobile communications that reliably reach every remote region, leaving no gaps on the map? Satellites play a key role in achieving this goal. In the future, however, not all satellites will be powerful enough […]
Amazon is preparing to launch its first full batch of Project Kuiper satellites next week, marking a crucial milestone in the tech giant’s bid to compete with Elon Musk’s Starlink.This post was originally published on […]
Blockchain technology was unveiled nearly 35 years ago, but it first became prominent more recently—in 2009, with the introduction of Bitcoin—giving this “digital ledger” an everyday, consumer purpose. However, while blockchains have been used for […]
An estimated 240 million calls are made to 911 in the U.S. each year, with wireless devices accounting for 80% or more of these calls. Making sure emergency calls connect and stay connected to 911 […]
The United Nations on Tuesday urged countries to boost protections amid a marked increase in efforts to interfere with satellite navigation systems like GPS that are critical for aviation and maritime safety.This post was originally […]
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 […]
High above the Arctic Circle, on the rugged terrain of Andøya, three ESA radionavigation engineers take a rare moment to unwind with a game of shuffleboard. Outside, sheep graze under the shimmering northern lights, a […]
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 […]
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.This post […]
