WiFi Positioning System (WPS) plays important role in Ubiquitous applications. It shows shorter response time than GPS and provides more precise position than Cell towers. It is widely used in hybrid positioning systems, e.g. GPS and WPS. The main problem of WPS is how to collect WiFi Access Point (AP) positions because the most of AP positions are not published. So thus, WPS providers collect AP...
Recently, WiFi positioning system (WPS) plays important role in ubiquitous applications. The main problem of WPS is how to collect WiFi access point (AP) locations because the most of the APs are usually installed on grass-root basis and their locations are not published. We use Locky.jp provided by Nagoya University Research Group as a WPS for our ubiquitous applications. However the precision of...
