Analog repeaters dramatically enhance millimeter-wave (mmWave) coverage in mobile networks by overcoming signal blockage, report researchers from Science Tokyo. As demonstrated in a field experiment at Ookayama Campus, low-cost repeaters connected either wirelessly or via optical fiber offer a promising solution for 5G and 6G networks. Both configurations achieved over... Read more
Just because Elon Musk and Jeff Bezos aren't the best of friends, and Amazon's Project Kuiper will directly compete with SpaceX's Starlink satellites for broadband internet, doesn't mean everyone can't still get along.... Read more
Terahertz frequencies above 100 GHz offer extremely wide bandwidths suitable for next-generation wireless communications, and research toward their practical use is ongoing worldwide. In particular, the 150 GHz and 300 GHz bands are actively being studied in Japan due to their relatively low atmospheric attenuation, which enables stable signal propagation.... Read more
A research team affiliated with UNIST has unveiled a new semiconductor device optimized for the next-generation 6G era and autonomous driving, offering low power consumption and nonvolatile operation. This innovative device can also be integrated into variable filter circuits capable of tuning the central frequency band, paving the way for... Read more
Countries have come to rely on a network of cables and pipes under the sea for their energy and communications. So it has been worrying to read headlines about communications cables being cut and, in one case, an undersea gas pipeline being blown up.... Read more
Imagine a world where every smart device, from traffic sensors to wearable health monitors, can seamlessly communicate. This vision is at the heart of Massive Machine Type Communication (mMTC), a cornerstone of 5G and future 6G mobile networks.... Read more
Deep in Martu Country, the Rawa Community School has a new addition. Perched on the roof is a squat, sealed rectangle. Curved underneath, flat on top and angled toward the sky, it's a sight becoming increasingly familiar in regional Australia: Starlink.... Read more
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
The QUICK³ nano satellite will test components for future quantum satellite systems. The goal is to enable rapid and secure communication using quantum technology. Developed by a research consortium led by TUM professor Tobias Vogl, the satellite was launched into orbit on Monday, June 23, with a booster rocket from... Read more
In recent days, Iranians experienced a near-complete internet blackout, with local service providers—including mobile services—repeatedly going offline. Iran's government has cited cybersecurity concerns for ordering the shutdown.... Read more
United Launch Alliance took a week to reset, but was able to send up its second launch of the year, another mission for Amazon's effort to compete with SpaceX's Starlink internet constellation. The launch came just hours after SpaceX sent up its 50th rocket from the Space Coast this year.... 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....

A novel time-division MIMO technology enables phased-array receivers to operate faster with exceptional area efficiency and low power, as reported by researchers from the Institute of Science Tokyo. The proposed system significantly reduces circuit complexity for 5G and 6G networks, including non-terrestrial nodes, by reusing signal paths through fast switching.... Read more
Earlier today, Iranian officials urged the country's citizens to remove the messaging platform WhatsApp from their smartphones. Without providing any supporting evidence, they alleged the app gathers user information to send to Israel.... Read more
Number 1519 Connecticut Avenue lies just north of Dupont Circle, just over a 20-minute walk from the White House in Washington DC. In 1921, the inventor Charles Francis Jenkins set up his laboratory and offices there, upstairs from a car dealership.... Read more
