Provided technical oversight of Hughes design, testing and integration of the OneWeb Ground Systems and networks.Systems engineering, integration and testing of a ground-based Radio Access Network that served as the Gateway to interconnect fixed and mobile User Terminals (UT) to the Internet via a global constellation of Low Earth Orbiting (LEO) satellites using 4G LTE-Advanced air-interface protocol.

Mclean, Virginia

Lead systems engineer, for mission-critical 4G LTE network design and deployment for a major US Training and Systems Instrumentation program. Led the RF propagation/network planning of the 4G LTE cellular network and developed the initial product (cellular network) verification tests (IPVT) processes with a successful CDRL milestone completion.Led the development of a 4G LTE RAN demonstration (testbed) focused on First Responder mission critical communications. The testbed provided a fully functional test environment for implementing various mission critical first responder use cases such as priority access, context aware QoS prioritization for various incident user applications. Served as a Principal investigator in Internal Research and Development (IRAD) on secure wireless and mission-critical broadband communications systems. The research on secure wireless identified gaps in capabilities for secure mission-critical communications and recommended solutions to fill the gaps.
