Abstract
Provided is an apparatus for tracking an object. The apparatus includes a grid including a plurality of antennae arranged to form an array of cells in which the object can be tracked, and a communication tag provided to the object to be sensed for tracking a location of the object. A receiver is operatively connected to the antennae for transmitting an interrogation signal via the antennae and receiving a signal indicative of a location of the object within the array in response to transmission of the interrogation signal. A processor unit utilizes the signal to determine useful data indicative of the location of the object in the array, and a platform presents the usable data to a user to relay information about the location of the object.
