Abstract

In some implementations, a beaconing protocol can be used to broadcast beacon information to mobile devices. The beaconing protocol can be used by a Bluetooth Low Energy (LE) (e.g., Bluetooth 4.0) beacon to transmit a package of information that identifies the beacon and indicates the calibrated transmission power (e.g., measured power) of the beacon. The package of information can be configured by beacon providers and/or beacon installers at the locations where the beacons are installed. When a mobile device receives the beacon package, the mobile device can use the beacon identification information and/or the measured power of the beacon to determine a location (e.g., precise location, geofence location) of the mobile device. In some implementations, the mobile device can transmit the beacon information to a server and the server can determine the location of the mobile device and send location and/or content information back to the mobile device.

First claim

What is claimed is:

1. A method comprising:
broadcasting, from a beacon device a plurality of signals;
receiving a measured power value calculated based on received signal strengths of the plurality of signals by a calibration device within communication range of the beacon device;
generating a beacon payload that includes the measured power value, a first set of values for complying with a Bluetooth protocol and a second set of values that comply with a beacon protocol that is different than the Bluetooth protocol, where the second set of values include at least two values that identify, or are associated with, a company; and
broadcasting, from the beacon device, the beacon payload.

2. The method of claim 1 , where the beacon device is programmed by a network server to broadcast at a specified time interval.

3. The method of claim 1 , where the beacon device is programmed by a server computer to broadcast at a specified transmission power.

4. A method comprising:
receiving, at a mobile device, a signal from a beacon device over a Bluetooth communication link, where the signal includes a beacon payload that includes a measured power value, data identifying the beacon device, a first set of values for complying with a Bluetooth protocol and a second set of values that comply with a beacon protocol that is different than the Bluetooth protocol, where the second set of values include at least two values that identify, or are associated with, a company;
extracting from the beacon payload the measured power value, the second set of values and the data identifying the beacon device;
determining the received signal strength of the signal;
determining a distance between the mobile device and the beacon device based on the measured power value and the received signal strength; and
sending, by the mobile device to a server computer over a communication link that is different than the Bluetooth communication link, the distance, the second set of values and the data identifying the beacon device; and
receiving, by the mobile device over the communication network, content associated with the distance, the second set of values and the data.

5. The method of claim 4 , where determining a distance between the mobile device and the beacon device includes calibrating a distance function using the measured power value.

6. The method of claim 5 , where the distance function is based on a path loss model that uses an exponential decay curve that is calibrated based on the measured power value.

7. The method of claim 4 , further comprising:
extracting from the beacon payload information identifying a particular the beacon protocol; and
extracting data from the beacon payload according to the beacon protocol.

8. The method of claim 7 , where the the second set of values include values for identifying a location of the beacon device.

9. The method of claim 7 , further comprising:
receiving, from the server computer, a location of the mobile device.

10. A beacon device comprising:
one or more processors configured to generate a beacon payload that includes a measured power value, a first set of values for complying with a Bluetooth protocol and a second set of values that comply with a beacon protocol that is different than the Bluetooth protocol, where the second set of values include at least two values that identify, or are associated with, a company; and
a wireless transceiver coupled to the one or more processors and configured to:
receive the measured power value from a calibration device; and
broadcast the beacon payload to receiving devices.

11. The beacon device of claim 10 , where the beacon device is programmed by a network server to broadcast at a specified time interval.

12. The beacon device of claim 10 , where the beacon device is programmed by a network server to broadcast at a specified transmission power.

13. A mobile device comprising:
a wireless transceiver configured to receive a signal from a beacon device over a Bluetooth communication link, where the signal includes a beacon payload that includes a measured power value, data identifying the beacon device, a first set of values for complying with a Bluetooth protocol and a second set of values that comply with a beacon protocol that is different than the Bluetooth protocol, where the second set of values include at least two values that identify, or are associated with, a company; and
one or more processors coupled to the wireless transceiver and configured to:
extract from the beacon payload the measured power value, the second set of values and the data identifying the beacon device;
determine the received signal strength of the signal; and
determine a distance between the mobile device and the beacon device based on the measured power value and the received signal strength;
sending, by the mobile device to a server computer over a communication link that is different than the Bluetooth communication link, the distance, the second set of values and the data identifying the beacon device; and
receiving, by the mobile device over the communication network, content associated with the distance, the second set of values and the data.

14. The mobile device of claim 13 , where determining a distance between the mobile device and the beacon device includes calibrating a distance function using the measured power value.

15. The mobile device of claim 14 , where the distance function is based on a path loss model that uses an exponential decay curve that is calibrated based on the measured power value.

16. The mobile device of claim 13 , wherein
the one or more processors are further configured to extract from the beacon payload information identifying the beacon protocol; and extract data from the beacon payload according to the beacon protocol.

17. The mobile device of claim 16 , where the second set of values include a values for identifying a location of the beacon device.

18. The mobile device of claim 16 , further comprising:
receiving, from the server computer, a location of the mobile device.
