Pure LiFi transmits data using light (video)

BARCELONA, Spain -- Transmitting wireless data using radio waves is so old fashioned -- in the video above, you'll see the technology that sends data via light, and could stream Internet video to your TV from a light in your ceiling.

The system works by attaching an Ethernet-wired ceiling-based device to a standard LED light. The data about to be beamed through the air is sent to that bulb, which is instructed to flicker millions of times per second to communicate a signal -- kind of like an extremely speedy morse code.

The light signal -- which looks identical … Read more

Artemis Networks taps PureWave for pWave base stations

Last week Artemis Networks unveiled a technology that company founder Steve Perlman said would revolutionize the wireless industry. So far the world has seen a brief demonstration of the technology, called pCell, which promises to overcome the dropped calls, congestion and slow data rates of traditional wireless networks. It creates a "personal cell" around the antenna of mobile devices that support LTE and delivers the full spectrum concurrently to each device.

pCell's promise that thousands of people in a stadium could be watching HD video simultaneously on their mobile devices without any degradation sounds too good to … Read more

Babolat connected racket scrutinizes your every tennis move

Technology is sneaking into sports in all sorts of interesting ways. We've already seen an electronic basketball and a football helmet with concussion sensors. Now it's time for tennis to get its turn with the Babolat Play Pure Drive connected tennis racket.

The only clue that you're not playing with a regular racket is the LED light at the bottom of the handle. Otherwise, it has the same specs and feel of a normal Babolat Pure Drive racket. Sensors tucked into the handle measure power, impact location, number of strokes, spin, and type of stroke. It's charged via USB and lasts for up to six hours, which should get you through all but the most epic of tennis matches.… Read more

Pure pumps up streaming speakers at CES 2014, promises any Internet music service works

British tech company Pure is expanding its range of wireless speakers at CES, adding the $299 Jongo T4 model to its existing lineup.

Jongo speakers can stream music from an Apple phone or tablet, Android device, or a computer via Wi-Fi or Bluetooth. The T4 is a 50-watt model and joins the big-daddy T6 -- with 100W of power -- and the smaller T2, with 20W.

Until now, however, you've been limited in the streaming-music services you can use with the Jongos. Pure says that's about to end, announcing in a press release today that its products will … Read more

Six things Nokia did to make the modern cell phone

Editors' note: This column was originally published April 10, 2012, and has been updated with new information.

A bombshell of a tech headline hit in the late hours of Labor Day when we heard that Microsoft will spend $7.2 billion to acquire Nokia's devices and services unit and license the company's mapping services.

Even if you suspected this all along, and I know that a lot of people did, this is a very big deal. And I'm not just talking about the serious chunk of cash changing hands. Rather, I'm talking about Redmond taking control … Read more

Toshiba Excite Pure is a budget tablet that falls behind

The Toshiba Excite Pure is a forgettable 10-inch tablet that has a hard time challenging its competition. Even with a $300 price tag, the tablet isn't a good value thanks to its dated specs and poor screen resolution. In fact, it would be better to forgo the tablet altogether and either pay more for a higher-end 10-inch tablet, or size down to something smaller to get a better device.

Released in June, the Excite Pure is the lowest-priced in Toshiba's trio of new tablets in its refreshed Excite product line, with the Excite Pro and the Excite Write. … Read more

What's old -- and new -- about the Nokia Lumia 1020's camera

The Nokia 808 PureView was simultaneously ahead of the curve and behind the times.

Its camera is still one of the best to ever be in a smartphone (if not the best), but the most common lament I read was that it was running on a near-dead Symbian OS. Second to that was how thick and heavy it was, which was out of step with just about every new smartphone at the time. That all changes with the Nokia Lumia 1020.

The new Windows Phone 8 device is actually slightly thinner and lighter than the Lumia 920, which makes it … Read more

Deja vu: Yet another high-resolution audio 'format'

At first blush you might think the Audiophiliac would be thrilled to hear the news about the Universal Music Group's new High Fidelity Pure Audio Blu-rays -- and I would be, if I didn't know how this story plays out. In 1999 and 2000, the original high-resolution SACD and DVD-Audio formats debuted and quickly faltered. Then the record labels tried again with the DualDisc format in 2004, and that one came and went so fast most people didn't even know it existed. I heard a lot of those discs, and I didn't feel that most (but … Read more
