Richard Candell (Fed)
Project Leader (Industrial Wireless Systems)
Dr. Richard Candell brings over two decades of wireless systems engineering experience, specializing in research, design, and evaluation of wireless communication systems. His work spans both commercial and defense applications, where he has contributed significantly to secure and reliable wireless technologies. As a lead systems engineer, Dr. Candell developed strategies for spread spectrum interference cancellation and performance evaluation in satellite ground stations and mobile phased array transceivers. His patents cover successive interference cancellation and transmission burst detection for spread-spectrum satellite communications. He earned a Ph.D. in Computer Science from the University of Burgundy, France, and BS and MS degrees in Electrical Engineering from The University of Memphis. He joined the National Institute of Standards and Technology (NIST) in 2014. At NIST, Dr. Candell leads the Industrial Wireless Systems research laboratory, focusing on industrial wireless network performance in mobile robotics, manufacturing, and safety applications. He actively participates in IEEE societies as a Senior Member, including the Industrial Electronics Society, Instrumentation and Measurement Society, and the Robotics and Automation Society. Dr. Candell’s contributions extend to the Guide to Industrial Wireless Systems Deployments (NIST AMS 300-4), and he chairs the IEEE P3388 Wireless Performance Assessment and Measurement Working Group and the NIST Industrial Wireless System technical interest group.
Awards
Impacts
2024 William P. Slichter Award for spearheading a multi-year initiative to develop a precision channel-sounding apparatus, measure channel impulse responses at various industrial sites, and disseminate measurement data and channel models extensively used by wireless product developers and referenced by researchers. This resulted in numerous publications and several international collaborations with corporations such as Intel, Yokogawa, Emerson Automation and Boeing. His chairmanship of the IEEE P3388 standardization effort and organization of NIST/IEEE industrial wireless workshops within the Industrial Electronics Society have fueled growth and interest in this important research domain.
2024 Bronze Medal Award for the development and optimization of wireless time-sensitive networking scheduling techniques that accommodate reliability protocols found extensively in industrial environments. Collaborating with industry partners, the group developed precision measurement capabilities, designed experiments, and developed award-winning solutions to protect critical traffic while accommodating non-critical traffic in industrial networks. Based on this work, the collaborating partner, Intel, influenced the IEEE 802.11 standard allowing ubiquitous support to industrial applications.
2019 Bronze Medal for developing innovative measurement methods, a state-of-the-art test bed, and extensive first-in-class measurement data sets that led to a comprehensive Guide to Industrial Wireless Systems Deployments.
IEEE Standard for the Performance Assessment of Industrial Wireless Systems (IEEE 3388-2025), a radio-frequency (RF) reference environment model, test methodology, evaluation process, and detailed signal specifications for the performance testing of industrial wireless networks.
