  • a) transmitting, by the communication resource controller, a communication message, wherein the communication message includes a message identification code and communication payload;

    b) determining, by a communication unit of the plurality of communication units, whether the message identification code substantially matches an identification code of the communication unit;

    c) when the message identification code substantially matches the identification code, accessing, by the communication unit, a database to determine a geographic communication area based on the message identification code, wherein the geographic communication area is defined by a set of geographic coordinates independent of radio frequency coverage area of the antenna;

    d) when the message identification code substantially matches the identification code, determining, by the communication unit, geographic location of the communication unit, wherein the geographic location is not based on the communication message;

    e) when the message identification code substantially matches the identification code, determining, by the communication unit, whether the geographic location of the communication unit is within the geographic communication area; and

    f) when the message identification code substantially matches the identification code, and when the geographic location of the communication unit is within the geographic communication area, receiving, by the communication unit, the communication payload.
