Intentionally Blank U.S. Department of Homeland Security Houston Datacasting Integration Pilot After Action Report HSHQPM-15-X-00122 July 2016 ix Johns Hopkins University Applied Physics Lab Pilot After Action Report Executive Summary The Johns Hopkins University Applied Physics Laboratory (JHU/APL), under the direction of the Department of Homeland Security (DHS) Science and Technology Directorate (S&T), recently tested a prototype datacasting system and a deployable cellular Long-Term Evolution (LTE) communications system. The datacasting system, developed by SpectraRep, was installed at the offices of Houston Public Media (Public Broadcasting Station KUHT). Parallel Wireless (PW) developed the deployable LTE communications system. Tests involved the technical aspects of both systems and emphasized the ability to integrate these systems into larger telecommunications architectures that could be used in support of public safety. The tests were conducted at various sites in Houston, Texas, on February 9-12, 2016. The National Geospatial-Intelligence Agency (NGA) acted as a partner for testing connectivity and the use of their apps on a mobile, deployable LTE system. The original objectives of these tests were to demonstrate the ability to feed data and video to the datacasting system from multiple sites and to connect the system to officers in the field via other networks. These objectives were expanded to include demonstration of an end-to-end solution
