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.

First claim

What is claimed is:

1. A system, comprising:
a first wireless device having a first range of wireless coverage;
a second wireless device having a second range of wireless coverage;
a third wireless device having a third range of wireless coverage and configured for wireless communication with the first wireless device and the second wireless device, the third wireless device configured to wirelessly receive synchronization information including a superframe from the first wireless device and transmit the synchronization information to the second wireless device,
wherein an operation of the first wireless device, an operation of the second wireless device and an operation of the third wireless device are coordinated based on the synchronization information; and
a portable wireless device configured for wireless communication with any of the first wireless device, the second wireless device and the third wireless device to receive a subset of the synchronization information,
wherein an operation of the portable wireless device is coordinated based on the subset of synchronization information.

2. The system of claim 1 , wherein the operation of the portable wireless device includes switching a wireless transceiver of the portable wireless device between an active mode in which power is consumed to a sleep mode in which power is conserved based on timing information included in the subset of synchronization information.

3. The system of claim 1 , wherein the operation of the portable wireless device and the operation of at least one of the first wireless device, the second wireless device and the third wireless device include enabling a user associated with the portable wireless device to access at least one of an application, an asset and a service.

4. The system of claim 1 , wherein the operation of the portable wireless device and the operation of at least one of the first wireless device, the second wireless device and the third wireless device includes a wireless data exchange between the portable wireless device and the at least one of the first wireless device, the second wireless device and the third wireless device based on the subset of synchronization information.

5. The system of claim 1 , wherein at least one of the first wireless device, the second wireless device and the third wireless device is arranged to simultaneously detect presence of a plurality of portable wireless devices within the range of wireless coverage of the at least one of the first wireless device, the second wireless device and the third wireless device.

6. The system of claim 5 , wherein the at least one of the first wireless device, the second wireless device and the third wireless device is further arranged to differentiate among the plurality of simultaneously detected portable wireless devices.

7. The system of claim 5 , wherein the at least one of the first wireless device, the second wireless device and the third wireless device is further arranged to track the locations of the plurality of simultaneously detected portable wireless devices.

8. The system of claim 5 , wherein the at least one of the first wireless device, the second wireless device and the third wireless device is further arranged to coordinate a plurality of data exchanges with the plurality of simultaneously detected portable wireless devices.

9. The system of claim 1 , wherein the third wireless device is further configured to wirelessly receive a security update from the first wireless device and wirelessly transmit the security update to the second wireless device.

10. The system of claim 1 , further comprising a central server configured to gather information from the first wireless device, the second wireless device and the third wireless device.

11. The system of claim 1 , wherein the superframe includes system information and a timing of a framing structure.

12. A method comprising:
wirelessly receiving, at a third wireless device, synchronization information including a superframe from a first wireless device;
wirelessly transmitting, from the third wireless device, the synchronization information to a second wireless device, wherein the first wireless device and the second wireless device are within a wireless coverage range of the third wireless device;
coordinating an operation of the first wireless device, an operation of the second wireless device and an operation of the third wireless device based on the synchronization information; and
wirelessly transmitting, from any of the first wireless device, the second wireless device and the third wireless device, a subset of the synchronization information to a portable wireless device; wherein an operation of the portable wireless device is coordinated based on the subset of synchronization information.

13. The method of claim 12 , wherein the operation of the portable wireless device includes switching a wireless transceiver of the portable wireless device from an active mode in which power is consumed to a sleep mode in which power is conserved based on timing information included in the subset of synchronization information.

14. The method of claim 12 , wherein the operation of the portable wireless device and the operation of at least one of the first wireless device, the second wireless device and the third wireless device include enabling a user associated with the portable wireless device to access at least one of an application, an asset and a service.

15. The method of claim 12 , wherein the operation of the portable wireless device and the operation of at least one of the first wireless device, the second wireless device and the third wireless device includes a wireless data exchange between the portable wireless device and the at least one of the first wireless device, the second wireless device and the third wireless device based on the subset of synchronization information.

16. The method of claim 12 further comprising:
simultaneously, wirelessly detecting, by at least one of the first wireless device, the second wireless device and the third wireless device, presence of a plurality of portable wireless devices within a range of wireless coverage of the at least one of the first wireless device, the second wireless device and the third wireless device.

17. The method of claim 16 further comprising:
differentiating, by at least one of the first wireless device, the second wireless device and the third wireless device, among the plurality of simultaneously detected portable wireless devices.

18. The method of claim 16 further comprising:
tracking, by at least one of the first wireless device, the second wireless device and the third wireless device, the locations of the plurality of simultaneously detected portable wireless devices.

19. The method of claim 16 further comprising:
coordinating, between a portable wireless device and at least one of the first wireless device, the second wireless device and the third wireless device, a plurality of data exchanges based on the synchronization information.

20. The method of claim 12 further comprising:
wirelessly receiving, at the third wireless device, a security update from the first wireless device; and
wirelessly transmitting, from the third wireless device, the security update to the second wireless device.

21. The method of claim 12 further comprising:
gathering, at a central server, information from the first wireless device, the second wireless device and the third wireless device.
