About

Theodore S. Rappaport is a pioneering force in wireless communications, best known for his foundational work in millimeter-wave (mmWave) and Terahertz (THz) channel modeling. His research has been instrumental in shaping the physical layer of 5G and beyond, with a focus on ultra-wideband systems for high-speed data, sensing, and positioning. Rappaport’s major contributions include the development of wideband sliding correlation channel sounders, such as the 65 nm CMOS design that enables precise characterization of mmWave and THz channels—critical for emerging applications like wireless sensing and robotics. His work on public safety communications above 6 GHz, cited 54 times, addresses the need for fast, low-latency networks supporting aerial and vehicular modes. More recently, his 2025 study on statistical and deterministic radar cross section (RCS) characterization for Integrated Sensing and Communication (ISAC) at 25-28 GHz, though early in citation count, advances target identification for future wireless systems. With over 50,000 total citations and numerous accolades, including the Marconi Prize, Rappaport remains a visionary whose research continues to define the trajectory of wireless innovation.
