A wireless network with frickin’ laser beams on the ceiling


http://cdn.arstechnica.net/wp-content/uploads/2013/05/Beamcaster-ODU-640x423.jpgA new product called Beamcaster distributes beams of light to create wireless networks, providing an alternative or supplement to Wi-Fi and eliminating much of the cabling used to connect office workers to the Internet and corporate networks.RiT Wireless, the makers of Beamcaster, demonstrated the technology this week at the Interop networking conference in Las Vegas. A Beamcaster "optical distribution unit" is mounted on a ceiling, distributing invisible beams of light to eight "smart outlets." (You might call them "frickin' laser beams.") In a typical
setup, the smart outlets could be placed on top of a cubicle wall and hook up to PCs via Ethernet, giving workers access to the Internet and corporate networks. Connecting those smart outlets to standard switches would increase the number of PCs each smart outlet could connect to.

This setup reveals an obvious limitation—smartphones and tablets typically don't have Ethernet ports. However, a Beamcaster smart outlet can connect to a Wi-Fi router, distributing the signal to Wi-Fi-capable devices. Future versions of the smart outlet will have 802.11ac Wi-Fi built in, RiT Wireless CTO Erez Ben Eshay told me at the Beamcaster booth yesterday.

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

Flexible displays are the Future of IT Industry! A part from 4k and smart home appliances, the CES 2013 saw a lot of attention being drawn towards bendable, flexible displays. The elasticised display idea isn’t something new as we have seen hoards of device concepts being crafted around flexible, bendable and even foldable displays. These concept devices give us a futuristic feel, be it a flexible phone to be worn around the wrist or a phone that opens up to turn into a tablet or PSP-like device. But how far is this future? Nokia has been toying with the idea ever since we remember. The technology sounds very fascinating and the possibilities and the extent to which bendable displays could be used are vast and leave us spellbound. However, these have always been concepts and we haven’t seen any device materialise in the real world. There have been several technologies that were conceived in these years and all have been put to their practical use. But the bendable d

Xarius: Charge Your Mobile From Air

Xarius is a portable energy generator that allows to charge electrical appliances by the use of windpower in areas without electricity. Its lightweight and compact design makes the wind turbine to a perfect companion on backpacking trips with little luggage. It is composed of a foldable three-wing-system and an internal energy generator. The integrated rope makes it easy to adapt to any environment.Hooks are attached to both of its ends to tighten the rope and open the wings at the same time using the resulting tension. For convenient charging the battery is permanently installed, so that the electrical device can be charged inside the tent. The LED on the hook shows the current charge of battery. The pulsating orange indicates that the wind turbine has to recharge. Even at low wind speeds the blades begin to rotate autonomously.
