Wireless Network Synchronization of Cells and Client Devices on a Network
First Claim
1. A system comprising:
- a first wireless device having a known physical location, the first wireless device including;
a first wireless transceiver configured to transmit a beacon including a source identifier, the source identifier indicating a source of the beacon;
a second wireless device including;
a second 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 second wireless transceiver used to indicate when to switch from sleep mode to active mode based on time slot information;
processing circuitry operatively coupled to the second wireless transceiver and the timer, the processing circuitry arranged to switch the second wireless transceiver from the sleep mode to the active mode in response to input from the timer, the processing circuitry also arranged to monitor a first channel for the beacon during the active mode and, subsequently, to increase a channel number to a second channel and to reset the timer; and
a server configured to receive data from the second wireless device when in proximity to the first wireless device.

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.

11. A method comprising:
-
switching a wireless transceiver 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, monitoring a first channel for a beacon during the active mode, wherein the beacon includes a source identifier, the source identifier indicating, to a source of the beacon, the source of the beacon having a known physical location; increasing a channel number to a second channel; subsequent to increasing the channel number to the second channel, resetting the timer; receiving, from a first wireless device, a beacon including a source identifier, the source identifier indicating a source of the beacon; and sending data to a server, when in proximity to the first wireless device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
