A Wireless LAN-Based Solution for Issues Related to Positioning Information is Increasingly Desirable

Technologies for identifying the locations of persons and objects are advancing rapidly, and various means are used for the identification of locations such as GPS, base station-based positioning information, RFID and wireless LAN. The Wireless Positioning System of NEC Networks & System Integration Corp. enables the solution of customer problems using two methods. These are the method for positioning the target according to the difference in the times of receptions of radio waves and the method of detecting if the target is inside the target area according to the strength of the received radio wave. This article introduces the Wireless Positioning System of NEC Networks & System Integration Corp. by focusing on its mechanism and by considering cases of system introductions.
