Bluetooth Low Energy (BLE) has emerged as one of the reference technologies for the
development of indoor localization systems, due to its increasing ubiquity, low-cost …

Radio channel state information (CSI) measured with many receivers is a good resource for
localizing a transmitter device with machine learning with a discriminative model. However …

Indoor localization systems predominantly depend on one-dimensional signal
measurements, such as the Received Signal Strength Indication (RSSI) from Bluetooth or …

In this paper, we study fingerprinting-based indoor localization in commodity 5-GHz WiFi
networks. We first theoretically and experimentally validate three hypotheses on the channel …

Although positioning in both indoor and outdoor environments has been investigated in-
depth individually by various means, little attention has been paid to the intersected areas of …

Wi-Fi technology is widely used in indoor positioning systems due to its ubiquitous presence
in almost every building and its cost-effectiveness without requiring additional hardware. To …

Indoor 3D positioning is useful in multistory buildings, such as shopping malls, libraries, and
airports. This study focuses on indoor 3D positioning using wireless access points (AP) in an …

Passive, device-free indoor localization is a research field that has drawn the attention of
many researchers in the last years. A reliable, low-cost and accurate solution that does not …

Indoor localization has gained significant attention in recent years due to its various
applications in smart homes, industrial automation, and healthcare, especially since more …

Various machine learning techniques on indoor localization using radio signals are being
rapidly developed to achieve a sub-meter accuracy under noisy and complex environments …
