As the newly EMC materials, the authors have been proposed the bandpass space filters consisting the metal wire grid with negative relative permittivity and dielectric materials. In this study, the novel space filters using conductive film grid, i...
Currently, many researches are proceeded on location estimation using wireless LAN access points. In this research, we apply a particle filter, which is one of the time series filters, to examine the design method of its parameters and evaluate it...
In our laboratory, we study “area estimation” by Finger Printing for indoor commercial facilities and buildings. We study a method for updating DBs with user-acquired AP information. There is a problem of lowering the estimation accuracy due to th...
With the recent expansion of electromagnetic (EM) waves, undesired EM waves generated by device can cause malfunctions of other electronic equipment and communication failure. EM wave absorbers are widely used as countermeasures against these prob...
This contribution focuses on the accuracy and measurement cost of indoor Area Estimation using wireless LAN. The system estimates the area, such as a room or a shopping store, where the user is located. The user-measured AP information (UD), and t...
