Design And Implementation Of Wireless Positioning System

With the fast development of the Internet and the O2 O market, the area of data is coming.The urgent need of data requirements promotes the growth of the accuracy of wireless positioning system to meet the demand in the market. Designing the next generation version is around the corner. The traditional wireless positioning system can't satisfy with the management of the terminal in the enterprise. It is nessary for enterprises to understand the real-time data of the customer's terminal in time. In this case, the wireless positioning system come into being to meet the needs of the terminal positioning of the enterprise,which uses the application of the advanced filtering technology and related algorithms.This paper studies the current situation aboutthe development of the wireless positioning system, describing the concepts, principles and methods of the wireless positioning technology. It not only establishes models of system process; but also gives the system application architecture design. In addition, the system realizes the data collection function module, data filtering function module and data processing function module. The data collection function module is divided into three parts, which are AP channel switching and deployment, AP selection and data collection. The data filtering module is composed of two parts, RTT filter and Calman filter. The data processing module includes the FIFT transform, RSSI distance, RTT distance calculation, and the calculation of terminal coordinates. The coordination and cooperation of each module to complete the positioning of the terminal of the CUPID wireless positioning system. This paper is based on H3 C company CUPID wireless positioning system project development. In the data collection module the author details the AP channel switching and deployment and AP selection functions. In the data processing module, the attenuation coefficient of the RSSI distance is introduced in detailThe test results of CUPID wireless positioning system show that the tecnology can meet the requirements of different terminals in the current market positioning, and meet the current business to the collection of various terminal positioning data?CUPID wireless positioning system has been put into use and the effect of the practice has been approved by the user, some international airports in foreign countries have also been put into use,and achieved good results.
