Wi-Fi

Scientists at the University College London have set a new world record in wireless data transmission speeds, sending a blistering 938 Gigabits per second (Gbps) over the air through a combo of radio and light technology.

Wi-Fi security usually means keeping virtual intruders out, but a new system claims to use Wi-Fi networks to detect physical intruders. Gamgee’s Wi-Fi Home Alarm System can learn to recognize people who belong there and alert you to strangers.

Though most turntables will be cabled to a hi-fi amp, some allow streaming to Bluetooth speakers. Pro-Ject has announced a new addition to its T-series turntables that makes use of Wi-Fi technology for the promise of lossless multiroom playback.

Following much chatter online, Sonos has now officially announced the successor to its One compact speaker, adding Bluetooth but losing Google Assistant, plus the company is also betting on spatial audio with the launch of the six-driver Era 300.

RFID tags wirelessly provide information on products or other items, but they can only be read by dedicated portable devices. That may soon change, however, as a tag-integrated chip and a software update could allow smartphones to do the job.

By modifying an off-the-shelf Wi-Fi router with a firmware update and using a deep-learning algorithm, scientists have been able to detect breathing patterns that indicate respiratory distress in a medical mannequin.

For the last 4 years, high-end audio brand Devialet has been working to make the kind of impressive sound delivery found in its extraordinary Phantom speakers portable. The fruit of that labor is now available as the room-adapting 360-degree Mania.

If someone were planning on burglarizing a building, it would help if they knew where valuable gadgets such as smart TVs were located. A drone equipped with a cheap "Wi-Peep" device could allow them to do so, by seeing through the building's walls.

We've already seen systems that wirelessly transmit data via patterns of flickering light. A Saudi Arabian team has created a less energy-intensive alternative, that could use modulated sunlight in place of traditional Wi-Fi.

Last year, the Raspberry Pi Foundation launched the first product based on silicon that was developed in-house. Now the Pico microcontroller has been upgraded with built-in Wi-Fi for running new Internet-of-Things projects.

Because GPS doesn't work indoors, it can be difficult for robots to determine where they are within a structure. A new system could help, by using a building's existing Wi-Fi access points to guide wheeled or walking robots.

SpaceX has found a new home for its satellite-powered internet, inking a deal with independent air carrier JSX to offer onboard Wi-Fi to customers later this year, making the airline the first to carry SpaceX's Starlink internet service.
