A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that connects a resistor to an antenna. No need to send power to the antenna.... Read more
Sophisticated antenna arrays paired with high-frequency wireless chips act like superpowers for modern electronics, boosting everything from sensing to security to data processing. In his lab at Princeton, Kaushik Sengupta is working to expand those powers even further.... Read more
After the introduction of the fifth-generation technology standard for broadband cellular networks (5G), engineers worldwide are now working on systems that could further speed up communications. The next-generation wireless communication networks, from 6G onward, will require technologies that enable communications at sub-terahertz and terahertz frequency bands (i.e., from 100GHz to...

3D-printed radio antennas that could help bring stronger mobile phone signals and faster internet connections to people living in remote communities have been developed by researchers at the University of Sheffield.... Read more
State-of-the-art methods of information security are likely to be compromised by emerging technologies such as quantum computers. One of the reasons they are vulnerable is that both encrypted messages and the keys to decrypt them must be sent from sender to receiver.... Read more
EPFL researchers have collaborated with colleagues at Harvard and ETH Zurich on a new thin-film circuit that, when connected to a laser beam, produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics and telecommunications.... Read more
A questionnaire sent to South Australian households has found that more than half don't understand what a "smart city" means, despite Adelaide being one of the most wired cities in Australia with very fast internet speeds and networked sensors.... Read more
The evolution of next-generation cellular networks is aimed at creating faster, more reliable solutions. Both the next-generation 6G network and the metaverse require high transmission speeds. Visible light communication (VLC) is deemed an important ancillary technology to wireless communication.... Read more
When NASA docks two spacecraft in orbit, timing is critical. Their movements must be precisely synchronized with each other to prevent catastrophic failure, which means the computer networks that control their thrusters must not be disrupted for even a split second; instructions on exactly how and when to move must...

Delta Air Lines will provide free Wi-Fi service on most of its U.S. flights starting in February, CEO Ed Bastian announced Thursday at the CES technology trade show.... Read more
For years, the idea of 6G was thought to be science fiction. Now, it's closer than ever before, but Josep Jornet, an associate professor of electrical and computer engineering at Northeastern, says there's still room for improvement.... Read more
An ultra-wide-band receiver based on a harmonic selection technique to improve the operational bandwidth of 5G networks has been developed by Tokyo Tech researchers in a new study. Fifth generation (5G) mobile networks are now being used worldwide with frequencies of over 100 Hz. To keep up with the data... Read more
Several years ago, the government of Aotearoa New Zealand undertook an initiative to provide Internet access throughout the country. To observe the status of broadband adoption and usage in the rural areas, a group of final year research and development (R&D) undergraduate students with their supervisors conducted a statistical survey...

A group of about 20 tech-savvy engineers and programmers gathered Saturday afternoon at a Philadelphia bookstore to celebrate the installation of an old-fashioned public pay phone.... Read more
New signal-processing algorithms have been shown to mitigate the impact of turbulence in free-space optical experiments, potentially bringing "free space" internet a step closer to reality.... Read more
