| Abstract(in English) | Recently, services such as crime prevention and navigation have been implemented with location information from mobile devices. For the further spread of such location-based services, it is important to make them available in wide areas and to improve location accuracy with low cost. In this paper, from the standpoint of a location-based service provider using PHS, we consider the use of signal strength obtained through system training for improvement of location accuracy. However, training data acquisition over a wide area requires a large amount of human labor. So we propose a mechanism to collect training data autonomously, with the use of base stations with known locations, and without requiring the service provider to perform explicit training data acquisition. Then, we used wireless LAN for implementation and an experiment of our system. |
