First Claim
Patent Images
1. A method of determining a distance between a device and a target device, the method comprising:
- receiving, by the device, a first signal from the target device, the first signal being associated with a first intensity;
receiving, from a reference device located at a predetermined distance from the target device, intensity information corresponding to a second intensity associated with a second signal received by the reference device from the target device; and
determining the distance between the device and the target device based on the first intensity, the predetermined distance, and the intensity information corresponding to the second intensity.

Abstract
A method of determining a distance between devices, including receiving, by a device, a first signal from a target device, the first signal being associated with a first intensity; receiving, from a reference device located at a predetermined distance from the target device, intensity information corresponding to a second intensity associated with a second signal received by the reference device from the target device; and determining a distance between the device and the target device based on the first intensity and the intensity information corresponding to the second intensity.
