li-fi TECHNOLOGY

li-fi    TECHNOLOGY

A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.

Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).
It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.
It was tested this week by Estonian start-up Velmenni, in Tallinn.
Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 10Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.
It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.
Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now Mexican company Sisoft, working with researchers from the Autonomous Technological Institute of Mexico (ITAM), has developed a wireless technology that transmits data in visible light emitted from LED lamps, while lighting the room at the same time. Called Li-Fi, which is short for light fidelity, the technology is what is known as Visible Light Communication (VLC). Unlike infrared based system. VLC involves transmitting data using light visible to the human eye. In this case it is transmitted as intermittent, imperceptible flickers of light emitted by LEDs. The team started out with audio, cabling up a protoboard table to a smartphone via its 3.5 mm audio jack. The protoboard table converted the audio signal into an optical signal that is transmitted by a special emitter across the spectrum of light generated by an LED lamp. At the receiving end, a receptor located in a speaker captured the signal and converted it back into an audio signal that was played by the speaker.

For wireless internet transmission, the principle is the same but makes use of a receptor device designed to be placed above a router. The router incorporates an LED lamp to transmit data so anyone falling within the halo of light emitted by the LED will be in range. However, only those with a receptor/transmitter device will be able to send and receive the signal.

The Sisoft team says it has used the technology to transmit audio, video and internet at rates of up to 10 gigabits per second. This is an improvement over similar Li-Fi systems developed at  siemens and pennsylvania state university that achieved transfer rates of 500 Mbps and 1.6 Gbps, respectively.

In addition to its impressive transfer rate, Sisoft also highlights other benefits of the technology. Since the data is transferred via light, there is no way to hack it, making it safer, (although no mention is made of how easy it would be to take a peek at the data someone else is receiving). Additionally, it could be used in areas such as hospitals where radiation equipment can block or disrupt wireless signals. And of course, it provides illumination at the same time.

MOUSE FOR GAME LOVER

MOUSE FOR GAME LOVER

are you a great  fan of the Diablo series of games?

its third installation – the much-hyped Diablo III – might have left you with a bit of a grimace: it was damn hard.

I can report to you from the front lines of playing the game that yes, it was in fact as hard as discussed, and yes, it was in fact as long as rumored. I in fact failed to complete the game, after realizing that if one more of those flying  monsters killed me I was set to punch a hole through my monitor. But I digress.

One of the reasons that Diablo III was harder than it might have -been was its inclusion of some anti-macro technology, blocking users from running short scripts to help them launch repeat actions to speed along their gameplay. That was a no in the game, leading to more button mashing and general frustration THE GILA from GX gaming  that has a- surprising claim: it has both a CPU and a block of memory on-board, allowing it the capability to to get around certain in-game restrictions on macros. This means that, in theory, you could turn the tables on Diablo III and let you combo-power your way through the game with the click of a pre-programed button. And the mouse has oodles of them, with profile switching to allow you to jump from game to game, sans the need to re-code.....

The only real downside to the Gila is that it appears to be a mouse crossed with a Transformer that recently went through a blender the hard way...

The thing will set you back about $100, but is currently out of stock on Amazon. It’s a relatively new mouse, which we first spotted last night at CES Unveiled. Hello from Las Vega..

UPCOMING I PHONE 7 PLUS "AMAZING LOADED PHONE"

iPhone 7 Plus

iPhone 7 Plus”. The leaks generated significant buzz among techies as the source is arguably the most reliable one for advanced information on Apple’s upcoming products. In January of 2011, for example, Kuo almost perfectly predicted the iPad 2’s dual-core processor, screen resolution, and camera specs. He also correctly forecast several features of the iPhone 5, the discontinuation of the 17-inch MacBook Pro, and the redesign of the iMacs. But Kuo has also had his fair share of forecasting duds, including a prediction that a cheaper iPhone would be issued in 2013. Nevertheless, when it comes to forecasts on Apple products, hardly anyone can match Kuo’s accuracy.

Here are ten of Kuo’s most exciting predictions on Apple’s rumored iPhone 6S and IPhone 6S Plus (or iPhone 7 and iPhone 7 Plus), which will supposedly begin being mass produced in mid-to-late August Force Touch, already unveiled on Apple’s new 13-inch MacBook Pro and the Apple Watch, is a haptic technology that allows for the detection of the force of a tap and correspondingly responds uniquely to the variances in the applied pressure. But what benefit does the inclusion of such technology in the new iPhones really provide for their users? It’s actually pretty exciting. Because Force sensors allow for the detection of variances in the intensity of pressure applied, a hard press could enable particular capabilities, such as displaying the definition of a word or showing the preview of a file. Increased pressure could also indicate that the user wants to increase the rate at which a movie fast forwards or an image zooms. And not only taps, but also drags can be pressure-sensitive, meaning signatures could be drawn with the precision of a fountain pen, thus raising the possibility for electronically generated signatures to be just as or even more reliably verifiable than physically written ones.

THE FUTURES SMART HOME

The smart-home

The Internet of Things (IoT) has, for some time, suggested the inter-connectivity of otherwise separate devices and ecosystems; connected devices improving the practicality of our day to day lives. 2015 will see the IoT come to a domestic setting in a big way – with connected devices pulling the idea of the smart home sharply into focus. Thanks to prospective pushes from the likes of LG and Samsung, the smart home market looks set for sudden growth. The industry drive may mean surges in home sensor and security products (accessed and controlled via a smartphone). But it will also mean more smart devices aimed at monitoring utilities and home systems, aiding productivity and delivering entertainment.

DRIVERLESS CARS FROM GOOGLE

DRIVERLESS CARS FROM GOOGLE

Google on Friday announced it will begin testing prototypes of its fully autonomous self-driving cars on public roads. The vehicles won't roam too far from their Mountain View, California, home -- but this latest phase of testing could be critical both for cultivating positive consumer perceptions, and influencing future legislation affecting the nascent sector.Google has "a few" driverless car prototypes that will be testing this summer, said Chris Urmson, director of the Google Self-Driving Car Project. The prototypes are based on the familiar Smart Fortwo-like bubble designs that have become almost synonymous with self-driving cars.

Google previously had leaned heavily on modified Lexus RX450h SUVs to conduct its research into autonomous vehicle technologies. The SUVs have logged a close to a million miles of autonomous driving on test tracks and public roads since the start of the project, and they have been traveling roughly 10,000 miles each week, Urmson said.

Mountain View residents needn't worry about driverless cars flying around their neighborhoods at high speeds. The Google cars will operate at a "neighborhood-friendly" top speed of 25mph, and they'll have driver on board -- as well as a removable steering wheel, accelerator pedal, and brake pedal -- should manual operation be warranted, the company said.

In the coming years, Google wants to launch pilot programs so that it can learn more about how people would use driverless cars. For now, though, the company wants to gauge public perception of the vehicles and discover challenges unique to driverless cars.
