This experimental Android application was developed by NIST PSCR to enable public safety personnel to measure general LTE coverage quality using a standard smartphone. Source code is published on https://github.com/usnistgov/ as an SDK to allow developers to enhance the application or use it in other applications.

The application and SDK enable first responders and public safety personnel to survey and evaluate environments. 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.
