Abstract

A device for site monitoring is disclosed. The device may include a communication interface configured to receive site monitoring data from a site monitoring system. The communication interface may also be configured to wirelessly transmit the site monitoring data to a base station. The site monitoring data may include a device identification. The device also may include a processor and memory. The memory also may include two pseudonoise (PN) codes, namely a first PN code and a second PN code. The site monitoring data may be received from the site monitoring system. The site monitoring data may be spread using the first PN code to provide first spread site monitoring data. The first spread site monitoring data may be spread using the second PN code to provide second spread site monitoring data. The second spread site monitoring data may be transmitted using a burst direct sequence spread spectrum radio signal.

Claims

1. A device for site monitoring, the device comprising:

a communication interface configured to receive site monitoring data from a site monitoring system and configured to wirelessly transmit the site monitoring data to at least one base station, wherein the site monitoring data includes a device identification;

a processor in electronic communication with the communication interface;

memory in electronic communication with the processor, wherein the memory includes;

a device identification that identifies the device;

a first PN code;

a second PN code; and

instructions stored in the memory, the instructions being executable to;

receive the site monitoring data from the site monitoring system;

spread the site monitoring data using the first PN code to provide first spread site monitoring data;

spread the first spread site monitoring data using the second PN code to provide second spread site monitoring data; and

transmit the second spread site monitoring data using a burst direct sequence spread spectrum radio signal.

2. The device of claim 1, wherein the site monitoring data received by the communication interface from a site monitoring system was transmitted by a security device.

3. The device of claim 2, wherein the site monitoring data includes data received from an access control device.

4. The device of claim 2, wherein the site monitoring data includes data received from a security camera.

5. The device of claim 2, wherein the site monitoring data received from a site is received from a motion detector.

6. The device of claim 1, wherein the site monitoring data received by the communication interface from the site monitoring system includes wireless signals.

7. The device of claim 6, wherein the wireless signals are received by the communication interface from the site monitoring system using ultra wideband radio signals.

8. The device of claim 1, wherein the site monitoring data received by the communication interface from the site monitoring system are received over a network using mesh networking.

9. The device of claim 1, wherein the site monitoring data transmitted by the communication interface to the at least one base station includes wireless signals.

10. The device of claim 1, wherein the communication interface is configured to communicate with an antenna for receiving signals from the at least one base station.

11. The device of claim 10, wherein the signals received from the at least one base station include configuration data.

12. The device of claim 1, wherein the communication interface is configured to communicate with an antenna for transmitting signals to a site monitoring system.

13. The device of claim 12, wherein the device for site monitoring is a mobile device.

14. A system for site monitoring comprising:

a site monitoring system including at least one security device, wherein the site monitoring system is configured to transmit site monitoring data including at least one security device identification;

at least one device, wherein each device is configured to transmit its device identification and site monitoring data, wherein each device performs two spreading operations on the site monitoring data with two distinct PN codes, a first PN code and a second PN code, wherein each device transmits the spread site monitoring data using a burst direct sequence spread spectrum radio signal; and

at least one base station, wherein the at least one base station is configured to receive the burst direct sequence spread spectrum radio signal that includes site monitoring data, wherein each base station decodes the signal by first de-spreading with the second PN code, second applying any needed frequency correction, and third de-spreading with the first PN code.

15. The system for site monitoring as in claim 14, wherein each base station is further configured to provide the despread, demodulated and decoded site monitoring data with other information to a system for processing the despread, demodulated and decoded data.

16. The system for site monitoring as in claim 15 further comprising

a system for processing the despread, demodulated and decoded site monitoring data, and wherein the system for processing the despread, demodulated and decoded site monitoring data is further configured to store the site monitoring data and to further provide an interface for other systems to access the site monitoring data.

17. The system for site monitoring as in claim 16 wherein processing the despread, demodulated and decoded data includes associating the site monitoring data with a site identification.

18. The system for site monitoring as in claim 17 wherein processing the despread, demodulated and decoded site monitoring data includes sending a security alert to a client via a network operations center and wherein the security alert includes at least one of the following:

an email message to be forwarded to a client, a voice message to be forwarded to a client, or an email message to be forwarded to a service provider.

19. The system for site monitoring as in claim 18 wherein the one of the at least one devices is a mobile device.

20. A system for site monitoring comprising:

at least one security device configured to transmit site monitoring data including at least one security device identification, wherein the security device performs two spreading operations on the site monitoring data with two distinct PN codes, a first PN code and a second PN code, wherein the security device transmits the spread site monitoring data using a burst direct sequence spread spectrum radio signal; and

at least one base station, wherein the at least one base station is configured to receive the burst direct sequence spread spectrum radio signal that includes site monitoring data, wherein each base station decodes the signal by first de-spreading with the second PN code, second applying any needed frequency correction, and third de-spreading with the first PN code.
