Abstract
A method of generating a normalized matrix for use in determining one or more read accuracies of an RFID tag at selected points in space relative to a transmitter associated with the RFID tag. The method may further include using the normalized matrix to determine a particular read accuracy of the RFID tag at a particular point in space relative to the transmitter. Also, a method of generating a power scaling factor for determining the read accuracy of an RFID tag.
