Wireless Positioning Technology for CDMA System

Location services provide address information, and make terminal positioning and real-time detection and tracking. A solution to quickly-implemented and high-precision positioning is necessary for timely and accurate location services. There are 3 solutions to wireless positioning in the CDMA system. One is based on the network, the second on the mobile station, and the last on GpsOne technology. They are different in positioning precision, usability, positioning time, security and implementation cost. Therefore, they should be selected and applied according to specific requirements of networks. Based on network architecture, message bearing protocols and message transport modes, the implementation of the wireless positioning system has different models. Therefore, it is necessary for operators themselves to make rules of some details in the implementation.
