| The protocol is designed to be used with a large number of anchors covering a big area. Each anchor has a limited reach and covers only a small area, but by adding more anchors the system can cover an (virtually) unlimited area. At any point in the covered area, 5-10 anchors should be within range of a Tag. | The protocol is designed to be used with a large number of anchors covering a big area.
