1. A method for actuating or installing downhole equipment in a wellbore, comprising the steps off:

  • (a) providing, a first downhole structure that comprises an RF identification transmitter unit that stores an identification code and transmits an RF signal corresponding to the identification code;

    (b) providing a second downhole structure that comprises an RF receiver unit that can receive the signal transmitted by the identification transmitter unit, decode the signal to determine the identification code corresponding thereto, and compare the identification code to a preset target identification code;

    wherein one of the first downhole structure and the second downhole structure is secured at a given location in a subterranean wellbore, and the other is moveable in the wellbore;

    (c) placing the second downhole structure in close enough proximity to the first downhole structure so that the RF receiver unit can receive the RF signal transmitted by the RF identification transmitter unit;

    (d) comparing the identification code determined by the RF receiver unit to the target identification code; and

    (e) if the determined identification code matches the target identification code, actuating or installing one of the first downhole structure or second downhole structure in physical proximity to the other.
