Abstract

Cellular networks are more and more complemented by wireless LAN hotspots. However, when users are mobile, the small coverage area of hotspots is a challenge for the access network discovery and selection. Network selection mechanisms can be improved if, in addition to terminal-based measurements, hotspot information stored on location based systems is used. In this context, the coverage area is one of the most important characteristics of hotspots. This paper studies algorithms that are needed in information systems for the precise estimation of hotspot coverage areas based on field strength measurements performed by individual terminals. Different approaches for the iterpolation, vectorization and complexity reduction of measurement data are presented and evaluated by simulation of different scenarios. As a result, guidelines for the optimal parametrization of the algorithms are presented.
