LTE Coverage Tool

This experimental application was developed by the National Institute of Standards and Technology (NIST) Public Safety Communications Research Division (PSCR), with funding from the Department of Homeland Security Science & Technology Directorate (DHS S&T). Its purpose is to enable public safety personnel to measure general LTE coverage quality using a standard smartphone. Source code is published as a software development kit (SDK) to allow developers to enhance the application or use it in other applications.

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. DHS sponsored PSCR’s research in this area to determine whether first responders could use an experimental Android application to provide a reliable assessment of in-building LTE coverage. They found that non-experts could quickly master the operation of this system to measure general LTE coverage quality using a standard smartphone.
