Dr. Daniel Devasirvatham is an entrepreneurial, innovative and practical wireless engineer, researcher, manager & educator. His contributions extend from Land Mobile Radio and cellular/personal communications, to satellite links and rain radars. He made pioneering contributions to measuring and understanding the radio propagation channels in which these work. He invented and led the development of fast, computationally efficient, low-complexity models and algorithms to economically deploy communications systems, balancing coverage, capacity, and reliability. Using these, he conceived and built a family of RF design tools. He has published papers on RF propagation, coverage design and coverage assessment. He is currently working on Spectrum and Network sharing and Cognitive Radio.
In APCO, Daniel was in the Broadband and the Standards Development Committeea. He was a member of the APCO Homeland Security and Preparedness Committee after 9/11. Daniel was CTO of the DHS/OEC/ICTAP & NTIA/PSIC programs. He was active in First Responder Communications Interoperability, Project 25 Standards, and was the numbering administrator for the initial LTE broadband BTOP deployments. He was the technical leader of three Tiger Teams to solve vexing communications problems in sensitive installations in the US and overseas. He has guided new wireless technology research. He takes pleasure in sharing his knowledge through papers, talks and teaching. He holds three patents on predictive communications and a spectrum sharing technique. His interests include disaster recovery communications. He has published, spoken i FCC panels and chairs a special interest group in the software defined radio forum focused on Public Safety.
