Method and system for performing distance measuring and direction finding using ultrawide bandwidth transmissions
First Claim
1. A method 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, andwherein the operation of controlling the device function disables the device function when the determined distance is above the set distance threshold.
