The fingerprint technique is used as an indoor localization method. This study uses a CNN-based indoor fingerprint localization method. The estimation accuracy of CNN improves as the number of AP information (AP identifiers and received signal str...
In this study, we performed indoor location estimation using wireless LAN. The estimation method is based on the Finger Print method [1]. We measure the database (DB) and user data (UD) using wireless LAN radio waves to improve the location estima...
Today, we can know our outdoor location through global positioning system (GPS). However, it is not easy to estimate our indoor location because satellite signals are difficult to reach. Therefore, we study indoor localization using wireless local...

This contribution describe "area estimation" using Finger printing for indoor localization. A method for updating DBs with user-acquired AP information is necessary for the system. There is a problem of lowering the estimation accuracy due to the ...
The authors have been proposed the bandpass space filters consisting of the metal wire grid with negative permittivity and the dielectric materials. In this study, we designed the space filters using a conductive film sheet, instead of a metal wir...
Recently, location information has been emphasized with the spread of smartphones. The authors have been researching indoor location estimation with the goal of developing indoor navigation applications. In this research, we handle RSSI as time se...
In this study, the measurements of near magnetic field on the opening surface of metallic enclosure are investigated. First, the authors simulated the magnetic fields of a high power equipment enclosure including a power circuit. Next, the near ma...
First of all, as a research background, position estimation by GPS has become the mainstream in recent years, but it is known that position estimation accuracy deteriorates in places with poor radio wave environment such as indoors and underground...
