 wirelessly transmitting and receiving by the interrogator using a Time Division Duplex Multiplexing approach;   wirelessly transmitting and receiving by the transponder using a Time Division Duplex Multiplexing approach;   wirelessly transmitting by the interrogator, a plurality of interrogations comprising a periodic sequence of interrogations and a time separation between successive interrogations of less than 0.5 seconds;   wirelessly receiving by the transponder, the plurality of interrogations from the interrogator comprising the periodic sequence of interrogations and the time separation between successive interrogations of less than 0.5 seconds;   triggering by a first interrogation, of said periodic sequence of interrogations, the transponder to wirelessly transmit a signal so that said signal that is transmitted wirelessly by the transponder is received wirelessly by the interrogator;   transmitting by the transponder said signal wirelessly comprising a data packet, the data packet comprising an identification field that is uniquely associated with the transponder, followed by information that is provided to the transponder via a wireless transmission thereto from a device external to the transponder and then, followed by a cyclic redundancy check (CRC) field; and   wirelessly receiving by the interrogator said signal transmitted by the transponder comprising said data packet;   wherein the interrogator is configured to perform operations while being in motion relative to the transponder and while the interrogator is positioned at a predetermined location proximate to a highway; and   wherein the transponder is configured to perform operations while being in motion relative to the interrogator and while the transponder is positioned in a motor vehicle.    
     
     
       56. The system according to claim 55, wherein the operations further comprise:
 following wirelessly receiving by the interrogator said signal transmitted by the transponder comprising said data packet, and prior to a second interrogation of said periodic sequence of interrogations that follows said first interrogation, wirelessly transmitting by the interrogator data to the transponder.
