New Internet Cable Brings Unbelievable Speeds

Researchers say they used a single five-mile cable to transmit twice the amount of data that's currently used by the entire Internet. While it could one day mean faster connections for users, the main benefit of the research could be more ... energy-efficient data centers. The project involved the Technical University of Denmark and the Chalmers University of Technology in Gothenburg. They explored the way most high-speed data connections today involve encoding signals to transmit as light. The key was combining a single laser with a specially-designed optical chip. This breaks the light into 223 ... (view more)

Google Uses Lasers for Broadband Internet

Google says it has successfully used beams of light in the air to carry an Internet signal. It says the technology won't work everywhere but could be a useful solution in specific places. Project Taara works on a broadly similar principle to fiber ... optic cables, with pulses of light carrying a signal that translates into the 0s and 1s of computer code. The "Free Speech Optical Communications" system uses a narrow beam of light invisible to the human. It's a similar technology to that which Google used in a previous project to connect balloons in the sky. The new system instead connects ... (view more)

Scientists use Light, Sound to Produce 100 Gbps Internet

Researchers believe a new type of cable could carry Internet data at speeds 100 times greater than even the fastest on offer today. The new technology could benefit hospitals and research facilities in particular. The technique was developed by ... researchers at universities in Leeds and Nottingham in the United Kingdom, and is based around similar technology found in fiber optic cables. Those are the fastest data-carrying cables and work by sending pulses of light down a tiny transparent tube. By far, the greatest benefit of utilizing fiber optic cables is that it can transfer data over long ... (view more)

New 'LiFi' Gets 8 Gigabit Speed; Faster than WiFi, 5G

Light could be the key to solving one of the big problems of faster mobile Internet. But the technology, which uses spotlights to send out signals, has some limited range of uses. The technology developed by pureLiFi works on a simple principle: ... rather than using radio waves to transmit data (as does WiFi), it uses light waves. A demo of the system uses ceiling spotlights which blast out light in a cone shape. To the human eye it looks like an ordinary constant light supply. In fact it's actually flickering at incredibly high speeds to create a pattern. 5G Signals Hurt By Walls A plug-in ' ... (view more)

Audi to Reveal Red Light Secrets

Audi will soon fit its cars with a technology that can coordinate with traffic lights in several US cities. According to Audi, the feature is being billed as more about convenience, rather than a safety measure. The new feature is being built into ... an existing navigation and information service called Audi Connect, which carries a $25 a month service fee. The feature will involve an extra display on the dashboard that coordinates wirelessly with traffic signals and shows the driver how long they have until the light will turn green if at a full stop. The theory is that this will let drivers ... (view more)

Grocery Store Uses LED Lights To Track Customers

A French grocery chain is turning its overhead lighting into a way to send special offers directly to shopper's phones. It's seen as a way to experiment with technology, while still serving a more basic function. The lights are created by Philips ... and are being tried at a Lille branch of Carrefour, one of France's major chains of food and home goods stores. The entire store has been refitted with LED bulbs. Unlike ordinary bulbs, these transmit a signal by emitting light at a specific frequency for each bulb. The light can't be seen by the human eye; however, the front-facing ... (view more)

Philips LED Light Bulb Lasts 25 Years, Costs $60

The good news: Philips has launched a brand new light bulb designed to last for 20 years or more and save hundreds of dollars in electricity charges before needing replacement. The bad news: The bulb carries a retail price tag of $60. The new ... Philips bulb is a prime example of alternative energy-saving technology that wallops the inefficiency of today's conventional but popular devices. The reason: Traditional light bulbs work by heating a thin metal filament inside a glass bulb. While this produces light from the glowing filament, it also wastes a lot of the energy. In fact, conservationists ... (view more)
