Wi-Fi

Utilizing a new technique, ordinary wall-penetrating Wi-Fi signals could reportedly now be used to identify a person within a house.

The next generation of Wi-Fi is here, with improved capacity, better performance in crowded networks and a welcome speed boost of up to 40 percent.

Last month, Ikea and Sonos announced that they were collaborating on a new range of light and sound products. Now the Symfonisk range has debuted in Milan, and is made up of a table lamp with built-in wireless speaker and a small, versatile standalone streaming speaker.

In a new step towards truly wireless charging, engineers have developed an ultra-thin device that captures Wi-Fi signals and converts them into electricity.

​In what may be seen as a worrying development to those troubled by the growth of the surveillance state, researchers at the University of California have demonstrated that they can count people through walls using only Wi-Fi signals.

Setting up a living room hi-fi system generally involves getting to grips with cables, lots of cables. But the audio landscape has changed in recent years. Yamaha has introduced a new turntable that's designed to bridge the gap between analog and digital music formats.

We've already seen plenty of weird and wonderful gadgets at IFA 2018, but sometimes the most useful devices come in the plainest form – and so it is with the Devolo Magic. The Powerline networking kit hits a new high of 2,400 Mbps, enabling you to get super-fast internet running through your home.

It’s an unfortunate truth that weapons and explosives in public places are an increasing problem. But many screening technologies are bulky and expensive, and require staff to operate. Now a new study has found a way to tap into a type of signal that’s already ubiquitous in public places – Wi-Fi.

​If you're lost or injured in the wilderness, there's a good chance that there won't be cellular coverage where you are – that means you can't just phone for help. Your smartphone may still get you found, however, thanks to a new app designed at Spain's Universidad de Alicante.

In today’s concrete jungle, pavement takes up a lot of space, so we might as well cram some smarts in there. Now NASA is installing a high-tech new path that lights up, emits Wi-Fi signals and generates electricity, due to greet visitors to the Kennedy Space Center.

Researchers from the University of Washington have 3D-printed objects and sensors that are able to communicate with Wi-Fi devices such as smartphones or computers without needing to be powered by batteries or a wall socket.

Over the last few years we've seen a big trend in regular household objects being turned into gravity-defying, levitating marvels. The latest device to float onto the scene is the Moon – a smart camera with a wide array of extra features.
