While the world sprints toward ever faster mobile speeds, another connectivity story is quietly unfolding at the opposite end of the dial. Low-frequency spectrum—the radio bands below one gigahertz (GHz)—is emerging as a practical workhorse for long-range, low-power connectivity.... Read more

Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that's hard to intercept. Using a phenomenon known as "negative luminescence," the system works by making signals blend perfectly into the background of natural heat radiation, such as can be seen with a thermal camera....

Faster, more secure connections from space could one day make broadband on planes, ships and even remote roads as easy as turning on a light. The European Space Agency (ESA), Airbus Defense and Space, the Netherlands Organization for Applied Scientific Research (TNO) and German payload manufacturer TESAT (as subcontractor) successfully...

A new study examining digital behavior in Taiwan suggests that simply having internet access is no longer enough to ensure digital inclusion—a finding with growing implications for the United States as governments, schools, and employers continue shifting services online.... Read more

The National Institute of Information and Communications Technology (NICT) has developed a hybrid signal processing method that integrates an annealing-based quantum computer with classical computing for next-generation mobile communication systems. By implementing this method into a base station, simultaneous communications with 10 devices were successfully demonstrated through outdoor experiments, addressing... Read more

The fifth-generation mobile communication system, also known as 5G, is expected to evolve as a critical infrastructure supporting individual users, industrial applications, and social systems. This requires access to broader frequency resources, but concerns have emerged regarding future congestion even in the existing frequency bands, creating a strong need to... Read more

As researchers around the world race toward the realization of 6G wireless communication systems, the need for antennas that can dynamically adapt to ever-changing signal environments has never been greater. A key requirement of 6G is intelligent beam control, which enables signals to be steered, shaped, and optimized in real... Read more

An optimal combination of energy-efficient 5G network features—including AI systems that let mobile mast and antenna base stations go into sleep mode when usage is low, and phones that avoid unnecessary background network checks—could help cut indirect carbon emissions across the U.K. economy by around 25 million metric tons of...

Researchers at Monash University and the University of Melbourne have developed a quantum-inspired approach to optical wireless communication that promises to make 6G networks faster, more reliable and energy-efficient. As the world moves toward 6G, devices and networks will need to handle more data, faster, and in smaller spaces than... Read more

It has long been considered common sense that a single device performs only one function. Just as tuning a radio to a different frequency changes the channel, systems that manipulate waves have traditionally been designed to operate at only one specific frequency, requiring different devices for different frequencies. Now, however,... Read more

A new transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 140-gigahertz territory, unlocking data speeds that rival those of physical fiber-optic cables and laying the groundwork for a transition to 6G and FutureG data transmission protocols....

The EU will not force the world's biggest tech companies to pay for the overhaul of Europe's telecoms infrastructure despite pleas from the industry, Brussels announced on Wednesday.... Read more

With $800 of off‐the‐shelf equipment and months' worth of patience, a team of U.S. computer scientists set out to find out how well geostationary satellite communications are encrypted. And what they found was shocking.... Read more

A research team affiliated with UNIST has introduced a novel, high-performance, and thermally stable polymer-based non-volatile analog switch. This next-generation device is as thin and flexible as vinyl, yet capable of withstanding high temperatures.... Read more

Australia has entered an era of climate instability, where communications during bushfires and extreme weather must perform under increasingly severe conditions.... Read more
