-===== System architecture =====+===== Design goals =====
  
-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 will be able to 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.

 Each anchor knows its own position in a global coordinate system and broadcasts this information in time stamped packets that are used by one or more Tags to estimate their position. Each anchor knows its own position in a global coordinate system and broadcasts this information in time stamped packets that are used by one or more Tags to estimate their position.
