Along this chapter, an indoor positioning system that uses wireless ZigBee technology is presented and evaluated. In this system, mobile wireless devices measure the level of the received signal from reference nodes, which are placed in well-known positions. With this information, the position is estimated and presented to the user in a graphical way. A precision study is presented, being this study done in function of positions and numbers of reference nodes. It is also analyzed the presence of obstacles in the system, and a study of maximum distance inter nodes that allow positioning with a minimum of quality in the results is done.
