Abstract: Provided herein is a system for transmitting data to an object travelling along a surface. The object preferably contains an antenna which produces a read range having a length (L) in the direction of travel and a width (W) substantially perpendicular to the direction of travel. A first plurality of RFID transponders may be positioned within a surface as a row which is substantially perpendicular to the direction of travel. A second plurality of RFID transponders may be positioned following the first row. Depending on the speed of the object travelling the surface at this location, more rows of transponders may be used. A method for placing the RFID transponders within the surface is also disclosed.

Abstract: Provided herein is a system for transmitting data to a motor vehicle travelling along a roadway. The motor vehicle preferably contains an antenna which produces a magnetic field having a length (L) in the direction of travel and a width (W) perpendicular to the direction of travel. A first plurality of RFID transponders may be positioned in the roadway as a row which is perpendicular to the direction of travel. A second plurality of RFID transponders may be positioned following the first row and offset from the first row. Depending on the speed of the vehicles travelling the roadway at this location, more rows of transponders may be used. A method for placing the RFID transponders within the roadway is also disclosed.
