As in-building Bi-Directional Amplifier (BDA) systems are increasingly deployed to improve emergency communications network coverage in critical buildings, the side effects of these systems can impair these networks outside of buildings. Interference caused by improperly designed or functioning in-building systems is increasingly causing reduced coverage or network outages that are intermittent and difficult to find and remediate.

In this session, we will present research and technology, funded by Department of Homeland Security Science & Technology Directorate, that helps assess in-building coverage as well as detect and locate interference that can harm emergency communications networks. We'll also cover case studies in analyzing these systems in major metropolitan areas, specifically come hear Harris County (TX) representatives share their perspective on this growing concern and how they are addressing the challenge.
