1. A method for detecting the presence of a wireless user device within a strict wireless zone and subsequently triggering a desired action, the method comprising the steps of:
maintaining a database storing identifying information for at least one wireless user device in association with instructions for initiating a desired action upon detecting that the wireless user device enters the strict wireless zone;
establishing the strict wireless zone using a set of one or more leaky feeder antennas connected to a transmission source; wherein the set of one or more leaky feeders includes a first leaky feeder and a second leaky feeder and the radiation patterns of the set of leaky feeder antennas defines the strict wireless zone;
determining with a processor whether the wireless user device is within the strict wireless zone based upon the strength of a signal received by the wireless device from the set of one or more leaky feeders or received by the set of one or more leaky feeders from the wireless device;
determining with a second processor the angle of approach or angle of departure of the wireless user device into the strict wireless zone based upon a first and a second signal wherein the first signal is received by the wireless device from the first leaky feeders or received by first leaky feeder from the wireless device and the second signal is received by the wireless device from the second leaky feeder or received by second leaky feeder from the wireless device; and
triggering the desired action based upon a determination by the processor that the wireless user device is within the strict wireless zone.
