About

Derek Caudill is a leading researcher in wireless communications, specializing in millimeter-wave (mmWave) channel characterization for 5G and beyond. His work focuses on understanding how radio signals behave in complex environments, particularly at 60 GHz, where high bandwidths enable ultra-fast mobile networks. Caudill’s major contributions include the development of an omnidirectional channel sounder with phased-array antennas, capable of capturing detailed angle-of-departure and angle-of-arrival data for multipath components. This system, described in his most-cited paper (34 citations), provides critical insights into beamforming and signal propagation. He also investigated penetration loss in indoor-to-indoor and outdoor-to-indoor scenarios, quantifying how building materials affect signal strength—a key factor for reliable 5G coverage. With over 49 citations across his top works, Caudill’s research directly informs the design of robust mmWave systems, addressing real-world challenges like interference and obstruction. His notable achievements include pioneering double-directional switched-antenna measurement techniques, which have become essential tools for characterizing high-frequency channels. Caudill’s work is vital for engineers and researchers striving to optimize next-generation wireless networks, making him a respected voice in the field of mobile communications.
