LED lightbulbs create wireless networks wherever they are installed

Various researchers have created ways to transmit wireless information from LED light fittings, to act as a form of enhancement to Wi-Fi based networks known as "Li-Fi." But now engineers at the University of Virginia (U.Va) have come up with a new twist on this theme – they claim to have created an algorithm that makes almost any device fitted with standard visible- light LEDs able to communicate with other equipment with similar LEDs. So, for example, the LED headlights in your car could communicate to the car in front of you through its LED taillights, or the LED display in your clock radio could tell the coffee maker to turn on via its indicator light.Read More

Silk LED bulb emulates natural sunlight

Our well-being and mood throughout the day is largely influenced by the light we are exposed to. Following this principle, a start-up called Saffron has developed the prototype of a LED light that can sync our internal clock to the natural shifting color spectrum of the sun. The light is called Silk by Saffron, and the designers claim it can improve our humor and sleep patterns by giving us get the right kind of light for the each time of the day.Read More

New invention expands Wi-Fi bandwidth tenfold

The vast range of Wi-Fi-enabled devices available today means that anyone could have several personal electronic devices all trying to connect to a network simultaneously. Multiply this by many hundreds of people in a busy public place with Wi-Fi connectivity and this often means that available bandwidth is greatly reduced. To help address this problem, researchers at Oregon State University claim to have invented a new system called WiFO that incorporates infrared LEDs to boost the available Wi-Fi bandwidth by as much as ten times.Read More
