Patent Images
1. A method for recognizing a target device, wherein the method comprises the steps of:
- A. sending a first and a second wireless signals to a plurality of devices;
B. obtaining, from each device, a first and a second signal strengths respectively representing the signal strength of the first and the second wireless signals received by the device, or a signal strength difference between the first and the second signal strengths;
C. determining the target device according to the obtained signal strengths or the signal strength differences.

Abstract
The present invention aims to provide a technical solution for recognizing a target device from a plurality of devices as follows: sending a first and second wireless signal to a plurality of devices and determining the target device according to the signal strength differences between the first and second signal strengths. By using the technical solutions of the present invention, the “near-far-effect” caused by a single antenna can be overcome, and different offsets in the measured received signal strengths caused by the diversity of the receiving antennas can also be eliminated, and thus the accuracy of recognition is improved efficiently.
