Abstract

Described herein are systems, methods and computer program products for controlling operation of wireless beacons, such as Bluetooth Low Energy beacons. Multiple beacons may be controlled centrally or may work together in a cooperative fashion such that signals can be exchanged between or repeated by beacons in order to allow for signals received at one beacon to reach another beacon without requiring further central interaction. Power settings of beacons may be altered to change power consumption or to change a detectable range of the beacons.

Claims

1. A computer implemented method, comprising:

starting, by a wireless beacon, an advertisement timer;

transmitting advertisement packets, wherein advertisement packets include an advertisement transmission power that is sufficient for the advertisement packets to be detected by wireless devices located inside a target area, and wherein the advertisement transmission power of the advertisement packets is insufficient for the advertisement packets to be detected by wireless devices located outside the target area;

starting an announcement timer when the advertisement timer elapses; and

transmitting announcement packets until the announcement timer elapses, wherein announcement packets include a transmission power that is greater than the advertisement transmission power, wherein the transmission power of the announcement packets is sufficient for the announcement packets to be detected by wireless devices located outside of the target area, and wherein receiving transmitted announcement packets at a wireless device facilitates a status identification corresponding to the wireless beacon.

2. The method of claim 1, wherein the wireless beacon is compliant with a Bluetooth specification.

3. The method of claim 1, further comprising:

resetting the advertisement timer; and

repeating the transmitting of advertisement packets.

4. The method of claim 1, further comprising:

resetting the announcement timer; and

repeating the transmitting of announcement packets.

5. The method of claim 1, wherein the advertisement timer has a longer duration than the announcement timer.

6. The method of claim 1, further comprising:

receiving a wireless communication providing instructions to change a configuration of the wireless beacon; and

changing a configuration of the wireless beacon.

7. The method of claim 1, wherein the wireless beacon is battery powered.

8. The method of claim 1, wherein transmission of one advertisement packet at the advertisement transmission power uses less battery power than transmission of one announcement packet at the announcement transmission power.

9. The method of claim 1, wherein an announcement packet is not an advertisement packet.

10. The method of claim 1, wherein the announcement packets are not detectable by wireless devices as advertisement packets.

11. The method of claim 1, further comprising:

receiving a scan request; and

transmitting a scan response, wherein the scan response includes status information associated with the wireless beacon, and wherein receiving the scan response at a controller facilitates management of the wireless beacon by the controller.

12. A system comprising:

one or more processors; and

a non-transitory computer readable storage medium communicatively coupled to the one or more processors, wherein the non-transitory computer readable storage medium includes instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including;

starting, by a wireless beacon, an advertisement timer;

transmitting advertisement packets, wherein advertisement packets include an advertisement transmission power that is sufficient for the advertisement packets to be detected by wireless devices located inside a target area, and wherein the advertisement transmission power of the advertisement packets is insufficient for the advertisement packets to be detected by wireless devices located outside the target area;

starting an announcement timer when the advertisement timer elapses; and

transmitting announcement packets until the announcement timer elapses, wherein announcement packets include a transmission power that is greater than the advertisement transmission power, wherein the transmission power of the announcement packets is sufficient for the announcement packets to be detected by wireless devices located outside of the target area, and wherein receiving transmitted announcement packets at a wireless device facilitates a status identification corresponding to the wireless beacon.

13. The system of claim 12, wherein the wireless beacon is compliant with a Bluetooth specification.

14. The system of claim 12, wherein the operations further include:

resetting the advertisement timer; and

repeating the transmitting of advertisement packets.

15. The system of claim 12, wherein the operations further include:

resetting the announcement timer; and

repeating the transmitting of announcement packets.

16. The system of claim 12, wherein the advertisement timer has a longer duration than the announcement timer.

17. The system of claim 12, wherein the operations further include:

receiving a wireless communication providing instructions to change a configuration of the wireless beacon; and

changing a configuration of the wireless beacon.

18. The system of claim 12, wherein the wireless beacon is battery powered.

19. The system of claim 12, wherein transmission of one advertisement packet at the advertisement transmission power uses less battery power than transmission of one announcement packet at the announcement transmission power.

20. A non-transitory computer readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations including:

starting, by a wireless beacon, an advertisement timer;

transmitting advertisement packets, wherein advertisement packets include an advertisement transmission power that is sufficient for the advertisement packets to be detected by wireless devices located inside a target area, and wherein the advertisement transmission power of the advertisement packets is insufficient for the advertisement packets to be detected by wireless devices located outside the target area;

starting an announcement timer when the advertisement timer elapses; and

transmitting announcement packets until the announcement timer elapses, wherein announcement packets include a transmission power that is greater than the advertisement transmission power, wherein the transmission power of the announcement packets is sufficient for the announcement packets to be detected by wireless devices located outside of the target area, and wherein receiving transmitted announcement packets at a wireless device facilitates a status identification corresponding to the wireless beacon.
