Abstract
A network for locating a wireless tag comprises a plurality of wireless nodes. The nodes are not connected together by a wired network. Each node is included in a floor tile for installation inside a building and configured to be wirelessly connectable to at least one other node. When the floor tiles are installed, the plurality of nodes form a mesh or grid and provide overlapping wireless coverage for locating the tag by reference to the mesh.
Claims19
A system for locating a wireless tag within a layer having a plurality of layer units, said layer comprising a plurality of independent wireless nodes, each node being included in a respective layer unit and configured to be wirelessly connectable to at least one other node, such that when said layer units are installed in a layer, said plurality of nodes have a determinable spaced arrangement, and provide overlapping wireless feedback to said tag by reference to said spaced arrangement,
- wherein the feedback from said plurality of nodes is used to determine a location of the tag.
A method of locating a wireless tag within a layer having a plurality of layer units using a network comprising a plurality of independent wireless nodes, each node being included in a respective layer unit, each node being and configured to be wirelessly connectable to at least one other node, the method comprising the acts of:
- determining a spaced arrangement of said plurality of wireless nodes;
- and
- providing overlapping wireless feedback to said wireless tag from said plurality of wireless nodes with reference to said spaced arrangement;
- and
- determining a location of the tag using the feedback from said plurality of nodes.
