Robust Indoor Distance Estimation Algorithms for Bluetooth® Channel Sounding

Bluetooth Channel Sounding is a powerful feature setting a clear and solid foundation for standardized and efficient ranging. In this presentation, we dive into the topic of distance estimation algorithms for Bluetooth Channel Sounding. First, we provide a high-level overview of algorithms available and how they work. Then, we discuss some of the parameters and variables that impact their performance. Next, we present experimental results for a suite of algorithms implemented by Infineon in hardware and characterized by their accuracy, robustness, and computational efficiency. Finally, we talk briefly about algorithms suitable for scenarios with multiple Bluetooth devices present, summarizing their advantages and limitations in various scenarios, and discussing how can they combine to achieve higher accuracy and robustness for distance estimation.
