Although it has developed higher data-rate radio frequency systems, data-compression, and other techniques to boost the amount of data that its current RF systems can handle, they can't keep pace with the projected data needs of advanced instruments and further human exploration. To break this bottleneck, NASA is turning to optical communications technology that would use lasers to increase data rates over existing systems by anywhere from 10 to 100 times. <a href="/web/20111006141250/http://www.gizmag.com/nasa-laser-communications-relay-demonstration/19946/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> </div> <div class="clear_both"> <h2><a href="/web/20111006141250/http://www.gizmag.com/full-duplex-radio/19765/">Full-duplex technology could double wireless capacity with no new towers</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111006141250/http://www.gizmag.com/author/darren-quick/">Darren Quick</a></p> <p><em>02:19 September 8, 2011</em></p> </div> <div class="summary_details_right"> <p></p> <p></p> </div> </div> </div> <center><a class="noback" href="/web/20111006141250/http://www.gizmag.com/full-duplex-radio/19765/"><img src="https://web.archive.org/web/20111006141250im_/http://images.gizmag.com/hero/full-duplex.jpg" title="Rice University graduate student Melissa Duarte with a 'full-duplex' test device, which us..." alt="Rice University graduate student Melissa Duarte with a 'full-duplex' test device, which us..."/></a></center> <div class="summary"> <p>Earlier this year, Stanford University researchers created a <a href="https://web.archive.org/web/20111006141250/http://www.gizmag.com/full-duplex-radio-technology-developed/17880/" target="_blank">full-duplex radio</a> that allowed wireless signals to be sent and received simultaneously, thereby doubling the speed of existing networks.

Researchers from the Fraunhofer Institute for Communication, Information Processing and Ergonomics, however, have developed an augmented reality system that lets those engineers provide real-time visual instructions to distant on-site technicians ... and it can be done without internet access. <a href="/web/20111006141250/http://www.gizmag.com/remote-augmented-reality-system-for-repairing-machines/19201/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> </div> <div class="clear_both"> <h2><a href="/web/20111006141250/http://www.gizmag.com/sleepwell-wi-fi-system/19085/">SleepWell system puts mobile devices to sleep to conserve power while waiting on Wi-Fi</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111006141250/http://www.gizmag.com/author/darren-quick/">Darren Quick</a></p> <p><em>00:10 July 1, 2011</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111006141250im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111006141250/http://www.gizmag.com/sleepwell-wi-fi-system/19085/#comments">2 Comments</a> </p> <p><img src="/web/20111006141250im_/http://www.gizmag.com/images/icons/splashyIcons/image_modernist.png" alt=""/> <a href="/web/20111006141250/http://www.gizmag.com/sleepwell-wi-fi-system/19085/picture/137034/">2 Pictures</a></p> </div> </div> </div> <center><a class="noback" href="/web/20111006141250/http://www.gizmag.com/sleepwell-wi-fi-system/19085/"><img src="https://web.archive.org/web/20111006141250im_/http://images.gizmag.com/hero/sleepwell.jpg" title="Wi-Fi hotspots may be proliferating, but so are the devices that access them (Image: Flori..." alt="Wi-Fi hotspots may be proliferating, but so are the devices that access them (Image: Flori..."/></a></center> <div class="summary"> <p>Although the number of Wi-Fi hotspots has increased dramatically in most places over the past few years, the explosion in the number of smartphones and laptops attempting to make use of such connections means that getting decent download speeds is as difficult as it always was. Not only is this frustrating, it can also be a major drain on the batteries of mobile devices. In an effort to address one of these problems, a Duke University graduate student has developed software called SleepWell that allows mobile devices to take a nap to save power while they wait for their turn to download. <a href="/web/20111006141250/http://www.gizmag.com/sleepwell-wi-fi-system/19085/">Read More</a> </p> </div> </div> <div class="summary_item "> <div class="summary_details"> <div class="sd_top"> </div> <div class="clear_both"> <h2><a href="/web/20111006141250/http://www.gizmag.com/urthecast-earth-video-platform/19020/">UrtheCast video platform will let users view Earth from space</a></h2> <div class="summary_details_left"> <p>By <a href="/web/20111006141250/http://www.gizmag.com/author/pawel-piejko/">Pawel Piejko</a></p> <p><em>11:16 June 24, 2011</em></p> </div> <div class="summary_details_right"> <p><img src="/web/20111006141250im_/http://www.gizmag.com/images/icons/splashyIcons/comments.png" alt=""/> <a href="/web/20111006141250/http://www.gizmag.com/urthecast-earth-video-platform/19020/#comments">4 Comments</a> </p> <p></p> </div> </div> </div> <center><a class="noback" href="/web/20111006141250/http://www.gizmag.com/urthecast-earth-video-platform/19020/"><img src="https://web.archive.org/web/20111006141250im_/http://images.gizmag.com/hero/urthecast-platform-4.jpg" title="UrtheCast is launching a streaming video platform of planet Earth, that will originate on ..." alt="UrtheCast is launching a streaming video platform of planet Earth, that will originate on ..."/></a></center> <div class="summary"> <p>Canadian-based company UrtheCast has announced a project intended to let a wider audience view the earth from space.
