2009-09-25 | Locating RFID Tags

Determing the position of RFID tags based on signals captured at RFID readers can be done by several methods. 

Assuming mobile tags moving in an area where stationary readers are located, a geometrical approach comes to mind rapidly. Here, the readers are the centres of balls and the tags are located based on intersections of the balls. 

To keep the numeric effort small, it is possible to introduce heuristics based on the specific configuration of tags, readers and application area.  How this is done for a special configuration is detailed
in this report.
