And such applications as long term evolution(LTE) ,wireless local area networks(WLAN) ,RFID and location based service(LBS) are essential in today's wireless communications industry. In this paper,both wireless location technology and its application are proposed,where our experimental research results and theoretical innovation are included.展开更多

The middleware is located between application level and hardware-device level in the hierarchical software structure, which is in further divided into three levels, i.e. data, logical and service respectively. The rationale for the design is based on the consideration of the performance, organization,maintenance, and upgrade factors.展开更多
