-This is work in progress. The specifications on this page may change at any time without backwards compatibility.  +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.
