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/20120104093256/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/20120104093256/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/20120104093256/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><img src="https://web.archive.org/web/20120104093256im_/http://images.gizmag.com/layout/icons/comments.png" alt=""/> <a href="/web/20120104093256/http://www.gizmag.com/full-duplex-radio/19765/#comments">1 Comment</a> </p> <p></p> </div> </div> </div> <center><a class="noback" href="/web/20120104093256/http://www.gizmag.com/full-duplex-radio/19765/"><img src="https://web.archive.org/web/20120104093256im_/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/20120104093256/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.
