<p>A device and a method for generating mobile location information, and a device and a method for recognizing a mobile location are provided to recognize locations of an object and a user and to use an inexpensive RF(Radio Frequency) module by analyzing patterns of RF signal strength information according to distance, thereby reducing system construction costs. A signal obtainer(201) inputs signal strength information received from a mobile node by a fixed node. A feature vector processor(203) configures a feature vector on the basis of the strength information of a received signal. The feature vector is a set of relative feature values of the mobile node for the fixed node. The feature vector normalizes the feature values to store the normalized values in DB(204).</p> |
