Abstract
A data processing system and method are described for determining a physical location of a client computer system. The client and server computer systems are coupled together to form a local area network. Identifying information is associated with a tag. The client computer system transmits a wireless query signal to a physical region. In response to the tag being located within the physical region, the tag receives the wireless query signal. In response to a receipt of the query signal by the tag, the tag transmits a reply signal. The reply signal includes the identifying information. In response to a receipt of the reply signal by the client computer system, the physical location of the client computer system is determined utilizing the identifying information.
