Researcher’s reveal 100 times faster Infrared based Wi-Fi system

Here is a great news.  Researchers at the Eindhoven University of Technology in the Netherlands developed a new infrared-based wi-fi system that offers lightning speed of 42.8Gbit per second which is 100 times faster.This new system, also known as 'Li-Fi', relies on central light antennas to beam rays of different wavelengths to wireless devices. This makes your network more secure and it won't be jammed by other networking devices. Since it relies only on light rays supplied
by an optical fiber with no movable parts, it can be called as maintenance free system with no power requirements.Henceforth, we can say this system is cheap and easy to set-up. The light antennas have a pair of gratings which emits the light rays of different wavelengths at different angles. So, another light antenna takes over, if your smartphone is out of the light antenna's line of sight. It is also said that there is no interference from a neighboring wi-fi network until now and the network tracks the location of all the device using its radio signal transmitted in the return direction. Researchers say that this technique is harmless because a safe infrared wavelength is used which does not affect your eyesight. This system has so far only downloaded the data using the light rays, whereas uploads are done using radio signals. Li-Fi may hit the stores in just five years according to researchers.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Bing Apps for Windows 8 get major updates

Late least year, Microsoft rolled out a half dozen Bing Apps for Windows 8 users, each one focused on a specific category, such as travel and sports. The apps were designed to offer “immersive vertical experiences,” and now, about six months later, a big line of updates for them is being pushed out. Users can grab the updates now by heading into the Windows Store and selecting the updates notification.

Syrian Electronic Army claims credit for CBS Twitter accounts hack

Yesterday, several of CBS ’s Twitter accounts were hacked, including its main account, and its accounts for 60 Minutes, 48 Hours, and CBS Denver. The hackers got into the account and tweeted a series of things relating to President Obama and the United States being in cahoots with Al-Qaeda . The tweets also had links that led users to malware-infested sites. While CBS was able to regain access to its accounts, it was unable to figure out who was behind the attacks, until now. The Syrian Electronic Army , the same group that hacked 3 of the BBC’s Twitter accounts, claimed
