Abstract

Wireless personal area network (Zigbee, Bluetooth, UWB) and wireless identification technologies (Near Field Communication (NFC), Radio Frequency Identification (RFID)) are implemented in particular client server functions and communications. Connected with an Authentication Server, a wireless HUB authenticates user identification and provides the user with access to secure data communication with a wireless terminal such as a cellular phone or a PDA. A Location Server provides user locations via methods such as RSSI, TDOA, and GPS and sends location information to a Center Control Server and the Authentication Server. With location information, the Center Control Server initiates and optimizes secure information processes and coordinates the functions of servers and user terminals.
