Abstract
Over the last few years, many positioning systems and information support systems using wireless LAN have been developed. Some systems use the received signal strength of a wireless LAN for positioning. However, the received signal strength differs depending on each terminal's wireless LAN adapter. It is important to investigate the differences among the received signal strengths for different wireless LAN adapters, because the differences among each adapter may cause an increase in location estimation errors. In this paper, we examine the differences among the received signal strengths for a number of wireless LAN adapters, and propose wireless LAN data usage using an ideal wireless LAN adapter. Using our method, we can improve the estimation accuracy of the location estimation systemKeywords
