| Abstract | ||
| Wireless Local Area Networks are becoming increasingly popular today especially those based on IEEE 802.11 b/g standard. In this paper, we study the implementation of positioning and tracking system for indoor areas using the existing wireless local area network infrastructure. Such systems make use of location fingerprinting technique rather than time or direction of arrival techniques for determining the position of mobile units. Fingerprinting technique operates by recording and processing the received signal strength information of the wireless clients that measured from multiple access points to provide the location of the user mobile unit. The methodology, positioning system stages (hardware and software) and data collection of the positioning system are presented. Analyzing the experimental results gives 2 meter accuracy, and shows that the accuracy and performance of the positioning system depends mainly on reference points density and number of access points in the infrastructure network. | ||
