Method and system for performing distance measuring and direction finding using ultrawide bandwidth transmissions |
摘要 |
A method is provided for enabling a device function at a local device based on distance information, comprising: establishing a communication link with a remote device over a UWB medium using a multiple access protocol; determining a distance between the local device and the remote device; and controlling a device function for the remote device based on the determined distance, wherein the operation of controlling the device function enables the device function when the determined distance is below a set distance threshold, and wherein the operation of controlling the device function disables the device function when the determined distance is above the set distance threshold.
