LOCATION AWARENESS SYSTEM USING RFID AND WIRELESS CONNECTIVITY APPARATUS FOR LOCATION AWARENESS SYSTEM USED THEREIN
First Claim
1. A location awareness system using RFID (radio frequency identification) comprising:
- a RFID tag disposed at a target object for location awareness;
a wireless communication apparatus for location awareness for identifying the target object through communicating with the adjacent RFID tag;
more than three fixed anchors for receiving information about the identified target object and measuring a distance to the wireless communication apparatus by communication with the wireless communication apparatus using a predetermined wireless communication scheme;
a coordinator for collecting the measure distance and the information about the target objects from each of the anchors; and
a server for calculating a location of the target object by receiving information about the measured distances and the target objects from the coordinator and calculating the location of the wireless communication apparatus using the received information.

Abstract
A location awareness system using RFID and a wireless communication apparatus for the location awareness are provided. The location awareness system includes a RFID tag, a wireless communication apparatus for location awareness, more than three anchors, a coordinator, and a server. The wireless communication apparatus identifies the target object with the RFID attached through communicating with the RFID tag. The anchors receive information about the identified target object and measuring a distance by communication with the wireless communication apparatus using a predetermined wireless communication scheme. The coordinator collects the measure distance and the information from each of the anchors. The server calculates a location of the target object by receiving information about the measured distances and the target objects from the coordinator and calculating the location of the wireless communication apparatus using the received information.

7. A wireless communication apparatus for location awareness, which communicates with a RFID tag attached at a target object and communicates with anchors to calculate a distance in a location awareness system, the wireless communication apparatus comprising:
-
a RFID reader for identifying the target object through communicating with the RFID tag;
a memory for storing information about the target object identified at the RFID reader;
a wireless transceiving unit for transmitting the information about the target object stored in the memory to the anchors and transmitting a response signal for a distance calculating signal to anchors using a predetermined wireless communication scheme; and
a micro controller for controlling operations of the RFID reader, the wireless transceiving unit and the memory. - View Dependent Claims (8, 9, 10, 11)
