Abstract

A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal location device with angle of arrival modeling.

First claim

What is claimed is:

1. A system for providing awareness in a multi-space environment, the system comprising:
an array of gateway devices, each gateway device being positioned within a space in the multi-space environment, each gateway device having a gateway device identification providing an accurately-known fixed location;
each gateway device of the array including:
a housing,
a plurality of wireless transceivers associated with the housing,
a processor located within the housing and coupled to the plurality of wireless transceivers,
a memory accessible to the processor, the memory including processor-executable instructions that, when executed, cause the processor to:
receive a beacon signal via the wireless transceiver from a proximate wireless-enabled personal locator device, the beacon signal including a personal locator device identification,
measure received incident of arrival of the beacon signal and a respective incident angle of departure of the beacon signal,
transmit a gateway signal to a server, the gateway signal including the personal locator device identification, the gateway device identification, and angle of arrival measurement; and

the server located within the multi-space environment and in communication with the array of gateway devices, the server receiving a plurality of gateway signals and utilizing angle of arrival modeling to determine estimated location of the proximate wireless-enabled personal location device.

2. The system as recited in claim 1 , wherein the wireless transceiver is configured to communicate with a standard selected from the group consisting of infrared (IR), 802.11, 3G, 4G, Edge, Wi-Fi, ZigBee, near field communications (NFC), Bluetooth and Bluetooth low energy.

3. The system as recited in claim 1 , wherein the gateway device further comprises a plurality of 2.4G wireless transceivers.

4. The system as recited in claim 1 , wherein the gateway device further comprises a set-top box.

5. The system as recited in claim 1 , wherein the gateway device further comprises a common space gateway device.

6. The system as recited in claim 1 , wherein the gateway device further comprises a gateway service device.

7. The system as recited in claim 1 , wherein the proximate wireless-enabled personal locator device further comprises a single button personal locator device.

8. The system as recited in claim 1 , wherein the proximate wireless-enabled personal locator device further comprises a proximate wireless-enabled interactive programmable device.

9. The system as recited in claim 8 , wherein the proximate wireless-enabled interactive programmable device further comprises a smart watch.

10. The system as recited in claim 8 , wherein the proximate wireless-enabled interactive programmable device further comprises a smartphone.

11. The system as recited in claim 8 , wherein the proximate wireless-enabled interactive programmable device further comprises a tablet computer.

12. The system as recited in claim 1 , wherein the server further comprises a hotel server.

13. The system as recited in claim 1 , wherein the server further comprises a back-office hotel server in communication with the array of set-top boxes.

14. The system as recited claim 1 , wherein the system further comprises an operational mode selected from the group consisting of alerts-enabled, service request-enabled, tracking-enabled, and non-tracking-enabled.

15. The system as recited in claim 14 , wherein in the alerts-enabled mode, the server receives a distress signal from the proximate wireless-enabled personal locator device.

16. The system as recited in claim 14 , wherein in the service-request-enabled mode, the server receives a service request from the proximate wireless-enabled personal locator device.

17. The system as recited in claim 14 , wherein in the tracking-enabled mode, the server maintains in memory a plurality of estimated locations with timestamps associated with the proximate wireless-enabled personal locator device.

18. The system as recited in claim 14 , wherein in the non-tracking-enabled mode, the server maintains in memory only the last known locations with timestamps associated with the proximate wireless-enabled personal locator device.

19. A system for providing awareness in a multi-space environment, the system comprising:
an array of gateway devices, each gateway device being positioned within a space in the multi-space environment, each gateway device having a gateway device identification providing an accurately-known fixed location;
each gateway device of the array including:
a housing,
a plurality of wireless transceivers associated with the housing, each of the plurality of wireless transceivers being part of a 2.4G multi-array of antennas,
a processor located within the housing and coupled to the plurality of wireless transceivers,
a memory accessible to the processor, the memory including processor-executable instructions that, when executed, cause the processor to:
receive a beacon signal via the plurality of wireless transceivers from a proximate wireless-enabled personal locator device, the beacon signal including a personal locator device identification,
measure phase differences between received incident of arrival of the beacon signal and a respective incident angle of departure of the beacon signal,
transmit a gateway signal to a server, the gateway signal including the personal locator device identification, the gateway device identification, and angle of arrival measurement; and

the server located within the multi-space environment and in communication with the array of gateway devices, the server receiving a plurality of gateway signals and measuring phase differences of the incident angles of arrival of each beacon signal and a respective incident angle of departure to determine estimated location of the proximate wireless-enabled personal location device.
