Abstract

A system and method for wireless synchronization on a network are disclosed. In one embodiment, the wireless device includes a wireless transceiver and processing circuitry. The wireless transceiver wirelessly receives synchronization information including a superframe from a first wireless, reader device, and wirelessly transmits the synchronization information to a second wireless, reader device and a portable wireless device, and to wirelessly detect a presence of a portable wireless device. The processing circuitry communicates synchronization information to the second wireless, reader device and portable wireless device. The superframe is used to synchronize a wireless data exchange between the third wireless, reader device and the portable wireless device.

Claims (30)

1. A system, comprising:

an apparatus, the apparatus comprising:

a wireless transceiver having an active mode in which power is consumed, and a sleep mode in which power is conserved;

a timer operatively coupled to the wireless transceiver used to indicate when to switch from sleep mode to active mode based on time slot information; and

processing circuitry operatively coupled to the wireless transceiver and the timer, the processing circuitry arranged to switch the wireless transceiver from the sleep mode to the active mode in response to input from the timer, the processing circuitry arranged to tune the wireless transceiver to a first channel during a first active mode, listen for a beacon transmission on the first channel during the first active mode, and responsive to an absence of the beacon transmission on the first channel, increase a channel number to a second channel, reset the timer, and tune the wireless transceiver to the second channel during a second active mode, wherein the wireless transceiver transmits identity information associated with the apparatus on one or more of the first channel and second channel.

2. The system of claim 1 , wherein the time slot information is received wirelessly by the apparatus.

3. The system of claim 1 , wherein the apparatus has a known physical location.

4. The system of claim 1 , wherein the apparatus has a known physical location that is a fixed physical location.

5. The system of claim 1 , wherein the identity information associated with the apparatus identifies the apparatus.

6. The system of claim 1 , wherein the apparatus wirelessly transmits data that completes a purchase transaction.

7. The system of claim 1 , comprising a server configured to receive data from a device when in proximity to the apparatus.

8. The system of claim 7 , wherein the server is further configured to track a location of the device.

9. The system of claim 2 , wherein a location of a device is based on determining that the device is within a wireless coverage range of the apparatus.

10. The system of claim 1 , wherein the apparatus enables a user to access at least one of an application, an asset, and a service when the apparatus and a device are within proximity of one another.

11. A method comprising:

switching a wireless transceiver of a device from a sleep mode in which power is conserved to an active mode in which power is consumed responsive to an expiration of a timer, the timer indicating when to switch from sleep mode to active mode based on time slot information;

tuning the wireless transceiver to a first channel during a first active mode;

listening for a beacon transmission on the first channel during the first active mode;

responsive to an absence of the beacon transmission on the first channel, resetting the timer and increasing a channel number to a second channel;

subsequent to increasing the channel number to the second channel, tuning the wireless transceiver to the second channel; and

responsive to receiving the beacon transmission on the second channel, transmitting identity information associated with the device on the second channel during a second active mode.

12. The method of claim 11 , wherein the time slot information is received wirelessly.

13. The method of claim 11 , wherein the device has a known physical location.

14. The method of claim 11 , wherein the device has a known physical location that is a fixed physical location.

15. The method of claim 11 , wherein the identity information identifies the device.

16. The method of claim 11 , wherein the device wirelessly transmits data that completes a purchase transaction.

17. The method of claim 11 , further comprising receiving data, at a server, from another device when the another device is in proximity to the device.

18. The method of claim 17 , further comprising tracking a location of the another device.

19. The method of claim 18 , wherein the location of the another device is based on determining that the another device is within a wireless coverage range of the device.

20. The method of claim 11 , further comprises accessing at least one of an application, an asset, and a service when the device and another device are within proximity of one another.
