Location Technology Research Under the Environment of WLAN

摘要

Introduced location technology based on wireless LAN (Local Area Network). Analyzed three kinds of commonly used localization methods at present, and pointed out their advantages and disadvantages. Combining triangle position with RSSI (Received Signal Strength Indication), developed the study of location technology base on WiFi (Wireless Fidelity) technology in this paper, and a new information security technique is introduced. Finally, prototype experiment network was set up for location simulation. The experimental result showed that the experiment network has higher precision on localization, and can change its configuration in order to meet the localization demand of different occasions, which indicates this network has good performance and extensive adaptability.
