Abstract: A 3-D verification system determines the volume effectively covered by a reader/integrator of RFID tags. This system is useful for displaying the distortions and the holes in an RF coverage region that exist within its volume. It also determines and displays how the coverage region changes as a function of the power supplied to the reader/integrator. An RFID reader/integrator is mounted in an anechoic chamber facing an array of RFID tags in close proximity to each other. Each RFID tag's position within the grid is prerecorded in a computer database. The tag arrangement and location is also displayed by a 3-D visualization program. Different tag arrangement configurations comprise different embodiments of the invention. Each is designed to provide coverage of the volume in a layered, preferably geometrically regular configuration.
