Abstract: A system for determining a location within an area defined by a grid of radio-frequency (RF) tag circuits includes RF exciters that are configured to emit unmodulated RF energy. The grid of the RF tag circuits are configured to receive the unmodulated RF energy from one or more of the RF exciters and to emit modulated RF energy. Each RF tag circuit may store information associated with a location of the RF tag circuit within the area and the modulated RF energy emitted from each RF tag circuit may carry the information.
