Slocalization. Low-power RF backscatter localization.
Slocalization is a system for indoor localization using UWB, backscatter, RF time-of-flight ranging. The system allows ultra low-power backscatter tags to be localized slowly (minutes-hours depending on distance) at decimeter accuracy. While the UWB backscatter signal would usually be well below the noise floor, the signal is integrated over time to enable its recovery.
