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 method of detecting a transmitting device within an obstruction rich environment comprising:

detecting a transmission signal from the transmitting device with at least one wireless transmission detection facility;

determining a signal type of the detected transmission signal by determining a wave shape of the detected transmission signal, wherein a signal strength of said detected transmission signal is greater than a known threshold value for a predetermined period of time, said predetermined period of time being less than an expected shortest period of time for a corresponding signal type,

providing a unique identifier and time code as an identification of said signal;

communicating signal information relating to the detected transmitting device from the wireless transmission detection facility to a central unit, said signal information including said identification;

determining a location of the transmitting device based on detection of said signal from at least one wireless transmission detection facility;

displaying information of the detection and location of the transmitting device through a user interface; and

providing information regarding the detected transmitting device to an action facility for causing actions related to the detected transmitting device.

2. The method of claim 1 wherein the wireless transmission detection facility is a dual dipole antenna.

3. The method of claim 1 wherein the wireless transmission detection facility is a dual dipole embedded antenna.

4. The method of claim 1 wherein the wireless transmission detection facility is tuned to receive cell phone transmissions.

5. The method of claim 1 wherein the wireless transmission detection facility is tuned to receive a frequency band of approximately 700 to 950 MHz.

6. The method of claim 1 wherein the wireless transmission detection facility is tuned to receive a frequency band of approximately 1.7 to 2.0 GHz.

7. The method of claim 1, wherein the wireless transmission detection facility is tuned to receive the transmission signal in frequency bands of approximately 700 to 950 MHz and 1.7 to 2.0 GHz.

8. The method of claim 1 wherein the obstruction rich environment is a correctional facility.

9. The method of claim 1 wherein the obstruction rich environment is a mall.

10. The method of claim 1 wherein the step of communicating the information relating to the detected transmitting device from the wireless transmission detection facility to a central unit involves wireless communications.

11. The method of claim 10 wherein the wireless communications are 802.11 communications.

12. The method of claim 1 wherein the step of determining the location of the transmitting device is accomplished through triangulation of the transmission from a plurality of wireless transmission detection facilities.

13. The method of claim 1 wherein the step of determining the location of the transmitting device is accomplished through a known location of the wireless detection facility.

14. The method of claim 1, wherein said location is determined based on at least one of:

a time of reception and a received signal strength of said received signal.

15. The method of claim 1, wherein the wireless transmission detection facility is composed of a plurality of direction antennas.
