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 […]

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 […]

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 […]

NEC Corporation has developed a power amplifier that will serve as a key device for mobile access and fronthaul/backhaul wireless communication equipment to enable high-speed, high-capacity communications for 5G Advanced and 6G networks. This power […]

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.This article was originally published […]

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 […]

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 […]

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 […]

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 […]

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 […]
