Abstract

In embodiments, a method of detecting a transmitting device within an obstruction rich environment is disclosed. The method may involve detecting the transmitting device with a wireless transmission detection facility; communicating signal information relating to the detected transmitting device from the wireless transmission detection facility to a central unit; determining the location of the transmitting device; displaying information of the detection and location of the transmitting device through a user interface; and providing an action facility for causing actions related to the detected transmitting device.

Claims

1. A system for determining the presence of a non-transmitting transmission facility comprising:

a transmitting device transmitting a plurality of frequencies within a range of frequencies, wherein said plurality of frequencies represent a sweep of said plurality of frequencies within said range of frequencies;

a receiving device receiving a return from selected ones of said plurality of frequencies, said return produced by an antenna associated with the non-transmitting transmission facility; and

a computer;

formulating a disturbance pattern based on said received returns, wherein said disturbance pattern includes said return from selected ones of said plurality of transmitted frequencies and an indication of those plurality of transmitted frequencies lacking a return, said indication of the plurality of transmitted frequencies lacking a return representing a null in the disturbance pattern;

comparing the null in the formulated disturbance pattern with a plurality of known disturbance patterns;

matching the null in the formulated disturbance pattern with at least one null in a corresponding one of the plurality of known disturbance patterns; and

determining an identity of the transmission facility based on the matched disturbance pattern.

2. The system of claim 1 wherein the plurality of known disturbance patterns are stored in a data base.
