Position Location Techniques in Wireless Communication Systems

Abstract: Development of wireless communication technology and widely use of wireless networks have made location-aware applications possible and necessary. Object positioning location is an essential element in many applications such as navigation, tracking, emergency service, location based services (LBS) and security. Position location refers to the functionality and events to estimate the location of a node of interest. Position location involve the coordinates of the node that may be in two or three dimensions, and contain information such as the latitude and longitude where the node is located. The positioning location ideally to be available everywhere, inside buildings, outside in the street, in the sea, etc. The positioning location of objects as well as of people is important. To keep track of objects positioning location can to assist improve safety and control logistics efficiently. As climate changes and irregular weather becomes more common, there will be an increased need to sense and monitor the environment. This thesis presents an overview of existing positioning location solutions of nodes in different wireless communication systems. Applications of positioning of nodes are discussed and few examples are reviewed. The methods used to determine the positioning location of nodes with the aid of mathematical concepts are also explained.
