Abstract

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 presence of a transmission facility comprising:

a transmitting device for transmitting each of a plurality of frequencies;

a receiving device for receiving a return of each transmitted frequency produced by an antenna associated with the transmission facility;

a computer for;

receiving the returned transmission frequencies from the receiving device;

formulating a disturbance pattern from said returned transmission frequencies;

comparing the disturbance pattern with a plurality of known disturbance patterns; and

determining a presence of the transmission facility based on the comparison.

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

3. The system of claim 1, the computer further:

determining a null within said disturbance pattern.

4. The system of claim 1, wherein the transmission facility is in at least one of:

a powered-on state, a powered-off state and a standby state.

5. The system of claim 1, wherein the plurality of frequencies are transmitted from a first frequency to a second frequency.

6. The system of claim 5, wherein the first and second frequencies represent edge frequencies of at least one known frequency band.

7. A null detector comprising;

a receiving system; and

a processor,

said receiving system providing at least one frequency to said processor;

said processor formulating a receiving pattern from said at least one frequency and determining a disturbance is said receiving pattern, said disturbance representative of a presence of an transmission device.

8. The null detector of claim 7, further comprising;

a transmitting system for sequentially transmitting said at least one frequency.

9. The null detector of claim 7, further comprising:

a data base for storing a plurality of disturbance patterns.

10. The null detector of claim 9, the processor further:

comparing said disturbance with said plurality of disturbance patterns; and

identifying said transmission device based on said comparison.
