Device and method for detecting presence of a wireless communication device

A detection device for detecting presence of a wireless communication device having an antenna with intrinsic characteristics, the detection device comprising:

• a transmitter that sends a first signal to the antenna of the wireless communication device;
• a receiver that receives a second signal from the antenna of the wireless communication device, the second signal being a first portion of the first signal that is reflected by the antenna based on intrinsic characteristics of the antenna;
• a memory element that stores intrinsic characteristic information for the antenna;
• and
• a processing element that determines presence of the wireless communication device by analyzing the second signal against the intrinsic characteristic information stored in the memory element to determine if the second signal matches any of the intrinsic characteristic information, wherein the processing element determines presence of the wireless communication device by further analyzing a relative location, a frequency of detection, and a personal identification information.
