Abstract

RFID tags to provide a relatively low power and power conserving wireless communication system to dynamically and automatically transfer all preselected data developed in designated digital devices to a centralized data processing system. Inclusion, in the target mobile wireless devices from which data is to be transferred, of an RFID tag, preferably passive, to minimize power consumption that is conventionally recognizable by a short range RF transceiver in the computer system to which data is to be transferred. Thus, each mobile wireless device being tracked includes a short range RFID tag, a short range RF transceiver and storage means for the digital data developed by the device that is to be transferred. The data processing system to which the transfer is to be made should include a short range RF transceiver for identifying all RFID tags within this short range boundary; and means, responsive to the system RF transceiver identifying the RFID tag in the mobile wireless device within said short range boundary, for transmitting a signal to said mobile device to trigger the mobile device transceiver to transmit stored digital data to the data processing system.

Claims

1. A computer controlled communication system for dynamically and automatically establishing communication between mobile wireless digital communicating devices and other data processors comprising:

moving a mobile wireless digital device including a short range RFID tag, a short range RF transceiver, and storage means for digital data into the reception boundary of a data processing system including a short range RF transceiver for identifying all RFID tags within said short range boundary whereby the transceiver is enabled to identify RFID tags;

responsive to said system RF transceiver identifying the RFID tag of said mobile wireless device within said short range boundary, transmitting a signal from said system transceiver to said mobile device; and

responsive to said signal, triggering the mobile device transceiver to transmit stored digital data to said data processing system.

2. The communication system of claim 1 wherein said RFID tag is passive.

3. The communication system of claim 2 further including means in said data processing system for transmitting data to said triggered transceiver in wireless mobile device.

4. The communication system of claim 3 wherein said short range RF transceiver in said data processing system and said short range RF transceiver in said mobile wireless device coxununicate with one another using 802.11 b standard protocols.

5. The communications system of claim 4 wherein:

said data processing system is a hone computer;

said mobile digital device is a personal electronics device; and

said stored digital data is data developed by the personal electronics device.

6. The communications system of claim 5 wherein said personal electronics device is a digital camera.

7. The communications system of claim 2 wherein said data processing system is also mobile.
