Isn't it cool to have an affordable internet connection from a light bulb? I found this post on Technology Blog's Facebook page:
Chinese Scientists Invent Lightbulbs That Emit Wi-Fi
A group of Chinese scientists at Shanghai's Fudan University have a bright idea: A lightbulb that produces its own Wi-Fi signal. According to Xinhua, the technology is called Li-Fi, and the prototype actually works better than the average connection in China.
As many as four computers placed near a Li-Fi bulb can connect to the net, using light frequencies rather than the usual radio waves. The bulb is embedded with a microchip that produces a signal, yielding rates as fast as 150 mbps—far faster than typical connection speeds in China.
One of the perks of Li-Fi is that it's affordable. Have a lightbulb and a Li-Fi kit? Boom—you have internet. Next month, researchers are showing off 10 sample kits at a trade show in China, and the country is moving in a direction that could make Li-Fi a practical and commercially viable asset—especially since, as Xinhua reports, Chinese people are quickly replacing old fashioned incandescent bulbs with LEDs.
Of course, there are still a few technical details—mostly dealing with microchip design and manufacturing—that would need to fall into place before Li-Fi becomes ubiquitous.
So for now, Li-Fi remains an experiment with a bright future.
The Galaxy Round – a curved screen smartphone has been officially announced. This first of it’s kind smartphone features a 5.7-inch 1080p Super AMOLED curved display, 2.3Ghz Quad-Core Qualcomm Snapdragon 800 SoC, 3GB RAM, 13MP back camera and 2MP front shooter, and LTE-A support.
Design wise, the back of the device will follow Note 3 and Note 10.1 2014 style and feature a faux lether back, and as you can see on press photos, a whole device will maintain curved shape.
Samsung says that the design enables the large screen to be easier to use with one hand, the phone also packs couple of software enhancement that takes advantage of the unique shape of device screen and body.
With the Galaxy Round lying on a flat surface, the user can tilt one side of it up for a quick look at notifications and status, a la the Active Notifications in the latest Motorola devices, or use the tilt to control media – Samsung calls this feature a Bounce UX.
Device will be available in Luxury Brown Color (more to follow later) for South Korean Carrier SK-Telecom within the upcoming days, with a price set to 1,089,000 won – which is about $1000 USD.
Featuring a 1.63-inch (4.1-centimeter) screen and 1.9-megapixel camera, the Gear will go on sale Sept. 25, Shin Jong Kyun, head of Samsung’s mobile business, said at the company’s headquarters in Suwon, South Korea. The device syncs with tablets and smartphones using Google Inc.’s Android software to make phone calls.
The Gear weighs 74 grams (2.6 ounces), is available in six colors -- including orange, gold and lime green -- and has an ultra-thin screen using organic light-emitting diode, or OLED, technology. Sales will begin in 140 countries, with the U.S. and Japanese debut in October. Price = $299 Like us on Facebook : www.facebook.com/technorandom
