<p>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.</p> |
