Rice University wireless researchers have found a way to make the most of the unused UHF TV spectrum by serving up fat streams of data over wireless hotspots that could stretch for miles. In a presentation today at the Association for Computing Machinery's MobiCom 2014 conference in Maui, Hawaii, researchers from Rice's Wireless Network Group will unveil a multiuser, multiantenna transmission scheme for UHF, a portion of the radio spectrum that is traditionally reserved for television broadcasts.
