Finger Print位置推定における受信信号強度の座標間補間によるデータベース作成時間短縮

抄録

In this paper, we consider position estimation by Finger Print method using RSSI of wireless LAN access point. Although it is highly accurate indoors, it is week to change in the environment and it is necessary to periodically update the database. Therefore, RSSI approximate expression is created from a part of measurement data and coordinate information, and an RSSI of other coordinates is created. This aims to reduce the number of measured coordinates. In this paper, it was confirmed that the estimation accuracy equivalent to the database measured at intervals of 3.6 m can be obtained by measuring at 7.2 m intervals.
