While accuracy of the data from UE measurements is much lower than that of specialized equipment, the application provides subjective assessments of coverage quality, using UEs which are already available to agencies and personnel.</p> <p>Release of the software application and SDK is the culmination of several years of research efforts under the In-Building Coverage Quality Measurement Tool project, conducted by NIST PSCR and the National Telecommunications and Information Administration (NTIA) Institute for Telecommunication Sciences (ITS). The goal of that project was to determine whether a UE (i.e., LTE phone) experimental application could be used to provide a reliable assessment of LTE coverage. The final report, which will be released by NTIA ITS in 2019, determined that "non-experts could quickly master the operation of this system and obtain results that are statistically equivalent to expert propagation measurement engineers.”</p> <p>DHS S&T instructed NIST PSCR to release the software in order to allow first responders to access and use the application, and external developers to use the source code as a base for further development.<br> </p> </div> </div> <div class="nist-block"> <h2 class="nist-block__title">Specifications/Capabilities</h2> <div class="text-long"><p>Android device, software version 4.4 (KitKat, API level 19) through version 9 (Pie, API level 28).</p></div> </div> <div class="nist-block"> <h2 class="nist-block__title">Scientific Opportunities/Applications</h2> <div class="text-long"><p>The LTE Coverage Tool application and SDK enable first responders and public safety personnel to survey and evaluate coverage by LTE networks in environments where incidents are ongoing or planned.
