Abstract
This publication describes determining techniques for selecting between a variety of wireless ranging protocols used to determine a distance between two computing devices. An application executing at a first computing device (e.g., mobile device, smartphone, smart watch, computerized glasses, rings, vehicle head unit etc.) may request the computing device determine the distance to a second computing device. The computing devices may determine a set of available ranging protocols (e.g., Ultra-Wideband (UWB), BLUETOOTH Channel Sounding, WIFI Round Trip Time (RTT), BLUETOOTH received signal strength indicator (RSSI), WIFI, RSSI, etc.) that both computing devices may utilize. The computing devices may determine the set of available ranging techniques based on the hardware capabilities (e.g., resource costs, storage space, communication capabilities, etc.) of each device and/or use case constraints (e.g., restrictions on location, technique availability, etc.). The first computing device may select a ranging technique from the set of available ranging techniques based on a set of preferences from the application (e.g., security level, power efficiency, accuracy, success, etc.). In this way, the first computing device may select the optimal ranging technique for an application to utilize to maximize success, scalability, and availability.
