Wi-Fi

Back in 2015, the Raspberry Pi Foundation launched a $5 project board called the Pi Zero for entry-level tinkerers. Wi-Fi and Bluetooth capabilities were added in 2017 for an extra five bucks, and now the Zero W has entered its second generation.

Ikea has teamed up with Sonos to add another product to the Symfonisk range that debuted in 2019 with a table lamp/speaker combo and a standalone streaming speaker. This time the collaboration has merged a picture frame with a Wi-Fi speaker.

Researchers have demonstrated a new approach to harnessing the power of ambient radio waves, developing a novel chip that can convert Wi-Fi signals into power for a small LED, and possibly other small electronics and sensors.

Everything needs to be online nowadays, from vending machines to smart speakers, but that costs in terms of bulk and energy use. Now researchers have come up with a chip that gets devices connected with 5,000 times less power draw than normal.

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.
