Abstract

Systems (100) and methods (200) for operating a sensor system. The methods comprise: performing first operations by a Wireless Sensor Network (102) to (a) configure operations of WSN end nodes (104, 134-138) and (b) control Bluetooth Low Energy (“BLE”) link activity within a BLE network; and performing second operations by the BLE network to (a) find people or objects (156) within a specified area and (b) provide services to users of mobile communication devices which are BLE enabled (152) and reside within the specified area.

Claims

1. A sensor system, comprising:

a Bluetooth Low Energy (“

BLE”

) network comprising at least two BLE enabled nodes between which a first BLE link is established as a point-to-point link for single-hop transmission; and

a Wireless Sensor Network (“

WSN”

) controlling BLE link activity within the BLE network such that the first BLE link is active in a first mode under a first condition and converted to a second mode under a second condition different from the first condition;

wherein the at least two BLE enabled nodes have an indirect non-BLE based network connectivity through the WSN.

2. The sensor system of claim 1, wherein the WSN further configures operations of WSN end nodes.

3. The sensor system of claim 1, wherein the at least two BLE enables nodes perform operations to facilitate (a) locating a person or object in a specified area or (b) a provision of services to users of mobile communication devices which are BLE enabled and reside within the specified area.

4. The sensor system of claim 1, wherein the point-to-point link is used exclusively for single-hop transmissions.

5. The sensor system of claim 1, wherein the WSN allows remote web-based control of the at least two BLE enabled nodes.

6. The sensor system of claim 1, wherein the sensor system comprises a security and access control system, a fire monitoring system, or a person or asset location system.

7. The sensor system of claim 1, wherein the at least two BLE enabled nodes comprise electronic window locks, electronic door locks, motion sensors, area security devices, fire detectors, electronic access cards worn by individuals, or tags secured to objects.

8. The sensor system of claim 1, wherein a first one of the at least two BLE enabled nodes comprises a BLE central node.

9. The sensor system of claim 8, wherein the BLE central node comprises a mobile communication device that is BLE enabled.

10. The sensor system of claim 8, wherein the BLE central node'"'"'s communication with the WSN is direct or indirect via a cell network.

11. The sensor system of claim 8, wherein a second one of the at least two BLE enabled nodes outputs an audio alarm, a visual alarm, a tactile alarm or a radio signature alarm message indicating a distance between the first and second ones of the at least two BLE enabled nodes.

12. The sensor system of claim 1, wherein the WSN communicates a command signal to at least one of the at least two BLE enabled nodes for disabling an auditory output or enabling circuitry for generating radio signature alarm messages.

13. The sensor system of claim 1, wherein the WSN communicates a command signal to at least one of the at least two BLE enabled nodes for enabling an audio, visual or tactile alarm.

14. The sensor system of claim 1, wherein the establishment of the first BLE link is at least partially controlled by the WSN.

15. The sensor system of claim 1, wherein the WSN causes a signal power, a duty cycle, an antenna pattern of a BLE antenna, a mode, or a security-related characteristic of one of the at least two BLE enabled nodes to change.

16. A sensor system, comprising:

a Bluetooth Low Energy (“

BLE”

) network comprising at least two BLE enabled nodes between which a first BLE link is established as a point-to-point link used exclusively for single-hop transmissions; and

a Wireless Sensor Network (“

WSN”

) controlling BLE link activity within the BLE network such that the first BLE link is active in a first mode under a first condition and converted to a second mode under a second condition different from the first condition;

wherein the at least two BLE enabled nodes have an indirect non-BLE based network connectivity through the WSN.
