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. <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/led-lightbulbs-wireless-networks/38358/" class="readmore_link">Read More</a> </article> <article class="article-summary article-summary--None" data-article="37207"> <div class="article-top" data-article="37207"> <a class="label" href="/web/20150905055645/http://www.gizmag.com/telecommunications/"> — Telecommunications </a> <h1 class="h2"><a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/facebook-free-video-messenger/37207/">Facebook rolls out free video calls for its Messenger mobile app</a></h1> <div class="clearfix"> <span class="pull-left"> By <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/author/nick-lavars/" rel="author">Nick Lavars</a> - April 27, 2015 </span> <a class="picture-count" href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/facebook-free-video-messenger/37207/pictures"> 2 Pictures </a> </div> </div> <div class="inline-item"> <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/facebook-free-video-messenger/37207/"> <img src="https://web.archive.org/web/20150905055645im_/http://images.gizmag.com/hero/facebook_messenger_video-2@2x.png" alt="Facebook has announced free video calls for its Messenger mobile app "> </a> </div> The world's largest social network has today added free video calls to its Messenger mobile app. The move pits Facebook against already established video chat services, such as Apple Facetime, Microsoft's Skype and Google Hangouts, affording users yet another way to get some remote face-to-face time with the tap of a button. <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/facebook-free-video-messenger/37207/" class="readmore_link">Read More</a> </article> <article class="article-summary article-summary--None" data-article="37127"> <div class="article-top" data-article="37127"> <a class="label" href="/web/20150905055645/http://www.gizmag.com/telecommunications/"> — Telecommunications </a> <h1 class="h2"><a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/google-project-fi-details/37127/">Google takes on US wireless behemoths with Project Fi</a></h1> <div class="clearfix"> <span class="pull-left"> By <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/author/will-shanklin/" rel="author">Will Shanklin</a> - April 22, 2015 </span> <a class="picture-count" href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/google-project-fi-details/37127/pictures"> 3 Pictures </a> </div> </div> <div class="inline-item"> <a href="https://web.archive.org/web/20150905055645/http://www.gizmag.com/google-project-fi-details/37127/"> <img src="https://web.archive.org/web/20150905055645im_/http://images.gizmag.com/hero/google-project-fi@2x.png" alt="Google's Project Fi is the company's new MVNO, and one of the most consumer-centric approaches to wireless that we've seen"> </a> </div> With Google Voice all but dead, it makes sense that the company was busy behind the scenes, cooking up a new angle for taking on the telecom industry.

This prevents ISPs from being able to throttle or block users' connections to certain websites, or to offer "Internet fast lanes" whereby large websites could pay for their content to be delivered at a higher speed.
