摘要： A system is provided for tracking a RFID tag within or outside of a cellular network. Upon receiving a request to track the RFID tag, the cellular network instructs each mobile host within the cellular network to track the RFID tag. When the RFID tag enters a coverage area of one of the mobile hosts, the ID of the RFID tag is communicated to the mobile host. Then, the mobile host obtains its location. At this point, if the mobile host is outside of the cellular network, the mobile host communicates with other mobile hosts within its coverage area such that all of the mobile hosts within its coverage area have the location and time stamp for the RFID tag. When one of these mobile hosts enters the cellular network, the mobile host communicates the location and time stamp for the RFID tag to the cellular network.

摘要： A first node in a network receives a timing packet containing time information, where the timing packet is originated by a time server. The first node then updates the time information in the timing packet to reflect a delay associated with communicating the timing packet over a network link. The first node then updates the time information in the timing packet to reflect the delay associated transfer of the timing packet through the node. The first node sends the timing packet with the updated time information to a second node to enable the second node to use the updated time information for synchronization of the second node. The process repeats across an arbitrary number of nodes to enable time alignment between the first node and final destination node.

摘要： A method and apparatus for correcting oscillator frequency drift due to crystal aging. Correction signals that reflect a difference between an oscillator timing signal and a reference timing signal over a reference timing signal interval are modeled so that auxiliary correction signals can be generated in the event of loss of the reference timing signal. A temperature curve is generated to model how temperature variation impacts oscillator frequency drift. A rate of frequency drift due to crystal aging is also determined. During loss of a reference timing signal, auxiliary correction signals can be generated to maintain the oscillator at a desired frequency until the reference timing signal becomes available again.
