Abstract: The invention relates to local positioning and more particularly to methods of searching and registering tags in a local positioning system. A method of registering tags in a local positioning system is provided. Registering is performed in near-field mode. Tag stores identifying data of the local positioning system. Positioning unit stores identifying data of the tag. Furthermore, a method of searching a tag registered in a local positioning system is provided. Positioning units send address search packets into the space of the local positioning system. Desired tag responds with a positioning pulse. There is also provided a method of searching identifying data of a tag not registered in a local positioning system. Positioning units send broadcast search packets into the space of the local positioning system. Bisection method is used to detect identifying data of the tag. The invention can reduce power consumption by the tag and the positioning unit, and eliminate overlapping the signals received from a plurality of tags.
