SyncScatter: Enabling WiFi like synchronization and range for WiFi backscatter
summary
SyncScatter demonstrates accurate synchronization to incident WiFi signals and sensitivity pushed to the theoretical backscatter link budget, backed by a modeling framework that derives optimal range and sync error tradeoffs. It implements a hierarchical wake-up protocol and a custom ASIC to achieve over 30 meters at 2 Mbps while consuming about 25.2 µW on average, showing concrete measurements and end-to-end implementation rather than just simulations or toy experiments.
