Positioning in indoor environments with low-cost Wi-Fi devices

Abstract

The development pace of research associated with location tracking is highly associated with the breakthrough of wireless sensor networks and wireless technologies, being explored in several different areas. A classic example is the Global Positioning System (GPS), in which satellites are used to send signals to receivers on Earth, which, in turn, use these signals to compute navigation information. In order to address the growing interest in the research for position tracking in indoor environments, it is necessary to rely on wireless devices based on Bluetooth technology or Wi-Fi (IEEE 802.11). The objective of this study is to show the development of applications using new Wi-Fi devices (ESP8266) for the estimation of positioning and location in indoor environments.
