Biography: 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.
Title
A NIST Perspective on Industrial Wireless for Operational Systems
Abstract: Assuring the performance of wireless connectivity in industrial spaces presents several challenges. Physical channel conditions can often suffer from severe path loss, blockage, and multipath due to the high-density of metallic objects in the surrounding environment. Industrial spaces are also impacted by non-network noise sources such as from welding and other machinery atypical of the home/office environment. Operational applications such as those found in manufacturing, construction, and energy production may require strict data delivery deadlines for precision control and safety systems. These types of requirements therefore necessitate the introduction of time-aware protocols and reliability enhancements such as with informational path redundancy in both time and frequency, for example, duplicated channel transmission, frequency hopping, and redundant-time transmissions. Careful testing of these systems is also important for helping to assure data delivery performance for operational systems. Dr. Richard Candell, Principal Investigator of Industrial Wireless systems at NIST, will present the NIST perspective on research and standardization in the industrial wireless sector with a focus on wireless time-sensitive networks, reliability enhancements, testbed activities, and performance evaluation through the IEEE P3388 working group activities.
