Explore a groundbreaking conference talk on RF-CHORD, the first RFID localization system designed to meet reliability, throughput, and range requirements for automating inventory tracking in high-performance logistics networks. Discover how this innovative system utilizes a multisine-constructed wideband design to process RF signals with a 200 MHz bandwidth in real-time, enabling one-shot localization at scale. Learn about the multiple SINR enhancement techniques implemented for range extension, as well as the kernel-layer near-field localization framework and multipath-suppression algorithm developed to reduce 99th long-tail errors. Gain insights into the empirical results demonstrating RF-CHORD's ability to localize up to 180 tags 6 meters away from a reader within 1 second, achieving a 0% miss reading rate and approximately 0.01% cross-reading rate in warehouse and fresh food delivery store deployments.
