Abstract(in English) Thanks to the great advances in wireless communication systems, many types of the wireless terminals are available. It is expected that various novel services emerge in Society 5.0 that is based on Internet of Things (IoT) by a high degree of convergence between cyberspace (virtual space) and physical space (real space). This report proposes that the deep learning baesd position estimation using the channel state information (CSI) feedback in wireless LAN systems. The proposed position estimation is based on a finger print method and requires only single access point (AP). The indoor environment is considered to be as a target. In the proposed model, recurrent neural network (RNN) was used to utilize the time domain characteristics and the input features for the model was provided based on the angle of arrival (AoA) estimation algorithms. To evaluate the estimation accuracy, we developed the autonomous locomotion robot and measured the wireless LAN feedbacks and position information of the robot. The accuracy of the position estimation and lifetime of the model are discussed in this report.
