Abstract

An aspect provides a method, including: receiving, at a low power wireless communication subsystem of an information handling device, a beacon from a wirelessly connectable device; determining, with the low power wireless communication subsystem, if the received beacon warrants executing a communication protocol; in response to determining the received beacon warrants executing a communication protocol, powering on a main system component and a higher power wireless communication subsystem; and establishing a wireless connection between the higher power wireless communication subsystem and the wirelessly connectable device. Other aspects are described and claimed.

Claims (20)

1. A method, comprising: receiving, at a low power wireless communication subsystem of an information handling device, a beacon from a wirelessly connectable device; determining, with the low power wireless communication subsystem, if the received beacon exceeds a predetermined threshold that warrants executing a communication protocol; in response to determining the received beacon warrants executing a communication protocol, powering on a main system component and a higher power wireless communication subsystem; and establishing a wireless connection between the higher power wireless communication subsystem and the wirelessly connectable device.

2. The method of claim 1 , further comprising, responsive to determining that the received beacon warrants executing a communication protocol, sending a wake signal from the low power wireless communication subsystem to a main system of the information handling device.

3. The method of claim 2 , further comprising, responsive to receiving the wake signal by the main system, shifting the main system to a higher power state.

4. The method of claim 3 , wherein shifting the main system to a higher power state comprises resuming the system from a suspended state.

5. The method of claim 1 , wherein determining, with the low power wireless communication subsystem, if the received beacon warrants executing a communication protocol further comprises:

inspecting a beacon characteristic.

6. The method of claim 5 , wherein inspecting a beacon characteristic comprises comparing a device identification to a stored set of device identifications.

7. The method of claim 1 , wherein the low power communication subsystem comprises a short range wireless communication subsystem with a receiver configured to receive the beacon.

8. The method of claim 7 , wherein the higher power wireless communication subsystem comprises a short range wireless communication subsystem.

9. The method of claim 8 , wherein the higher power wireless communication subsystem is of higher bandwidth than the low power wireless communication subsystem.

10. An information handling device, comprising: a low power wireless communication subsystem; a higher power wireless communication subsystem; one or more processors; and a memory operatively coupled to the one or more processors that stores instructions executable by the one or more processors to perform acts comprising: receiving, at the low power wireless communication subsystem of the information handling device, a beacon from a connectable device; determining, with the low power wireless communication subsystem, if the received beacon exceeds a predetermined threshold that warrants executing a communication protocol; in response to determining the received beacon warrants executing a communication protocol, powering on a main system component and the higher power wireless communication subsystem; and establishing a wireless connection between the higher power wireless communication subsystem and the connectable device.

11. The information handling device of claim 10 , wherein the acts further comprise, responsive to determining that the received beacon warrants executing a communication protocol, sending a wake signal from the low power wireless communication subsystem to a main system of the information handling device.

12. The information handling device of claim 11 , wherein the acts further comprise, responsive to receiving the wake signal by the main system, shifting the main system to a higher power state.

13. The information handling device of claim 12 , wherein shifting the main system to a higher power state comprises resuming the system from a suspended state.

14. The information handling device of claim 10 , wherein determining, with the low power wireless communication subsystem, if the received beacon warrants executing a communication protocol further comprises:

inspecting a beacon characteristic.

15. The information handling device of claim 14 , wherein inspecting a beacon characteristic comprises comparing a device identification to a stored set of device identifications.

16. The information handling device of claim 10 , wherein the low power communication subsystem comprises a short range wireless communication subsystem with a receiver configured to receive the beacon.

17. The information handling device of claim 16 , wherein the higher power wireless communication subsystem comprises a short range wireless communication subsystem; and further wherein the higher power wireless communication subsystem is higher bandwidth than the low power wireless communication subsystem.

18. A program product, comprising: a storage medium having computer program code embodied therewith, the computer program code being executable by a processor and comprising: computer program code configured to receive, at a low power wireless communication subsystem of an information handling device, a beacon from a connectable device; computer program code configured to determine, with the low power wireless communication subsystem, if the received beacon warrants executing a communication protocol; computer program code configured to, in response to determining the received beacon exceeds a predetermined threshold that warrants executing a communication protocol, powering on a main system component and a higher power wireless communication subsystem; and computer program code configured to establish a wireless connection between the higher power wireless communication subsystem and the connectable device.
