Tom leads the engineering services team that provides technical studies for clients needing to resolve spectrum sharing issues, including between commercial parties and the government. This team also mines all types of big data to create interactive displays and presents this information in easily digestible formats, to include maps or charts. The focus of the engineering team is on providing engineering insights that can guide government advocacy efforts utilizing state of the art technical tools. Tom provides advice and support of clients concerning the technical and policy implications for 5G (next generation mobile). He has worked directly with network providers and trade associations seeking new 5G spectrum for the mid-band (C-Band, CBRS, Lower 3.4 GHz bands) and high-band (24 GHz, 26 GHz, 28 GHz, 37 GHz, 47 GHz, 50 GHz). Tom was also the primary technical lead in the team representing T-Mobile in its merger with Sprint. In this role, he was responsible for developing technical and regulatory advocacy for T-Mobile, including working with the engineering team in the company in providing network build and coverage information for the combined company. Prior to working in the private arena, Tom worked at the FCC for nine years. During this time, he helped develop engineering and technical policy frameworks governing the commercial mobile services as well as overseeing the licensing of the same services. He was a key member of the team that developed the auction process for commercial mobile licenses as well as the development of the licensing system used by the FCC for these same services.
