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.
Claims20
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;
- receiving, from a reference device located at a predetermined distance from the target device, intensity information corresponding to a second intensity of 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 a first intensity of the first signal, the predetermined distance, and the intensity information corresponding to the second intensity.
A device for determining a distance between the device and a target device, the device comprising:
- a communicator configured to receive signals;
- a memory storing instructions;
- and
- a processor configured to execute the instructions to at least:
- control the communicator to receive a first signal from the target device,
- control the communicator to receive, from a reference device located at a predetermined distance from the target device, intensity information corresponding to a second intensity of a second signal received by the reference device from the target device, and
- determine the distance between the device and the target device based on at least a first intensity of the first signal, the predetermined distance, and the intensity information corresponding to the second intensity.
