1. A system for remotely opening a land vehicle door which moves through a volume of space defined by an opening envelope when the door moves from its closed position to its open position, the system comprising:

  • a mobile communication device supported on the vehicle for movement therewith and operative to produce a first signal in the form of a first electromagnetic field over a volume of space outside and adjacent the vehicle and defined by a field envelope;

    a hand-held communication device operative to detect the first electromagnetic field and produce a second signal in the form of a second electromagnetic field when the hand-held device is located within the field envelope, the mobile device being operative to remove identification data from the second signal, the identification data identifying the hand-held device; and

    control logic coupled to the mobile device, and being operative to determine if the hand-held device is an authorized hand-held device based on the identification data, the control logic being operative to determine if a pedestrian carrying an authorized hand-held device is located within the field envelope and to generate a door-opening command signal when the authorized device is located within the field envelope for a predetermined period of time wherein the mobile device is supported on the vehicle so that the opening envelope is in non-overlapping relationship to the field envelope.
