Extensão da API PreDetect : utilizando o Bluetooth Low Energy para detecção de presença de dispositivos móveis em ambientes indoor

Abstract

Positioning systems play an increasingly clear role in people’s lives, as they remain most of the time indoors. In this context, a range of possibilities arise, such as locally driven content delivery, location-based advertising, asset tracking, and more. But, unlike external positioning, indoor positioning does not have a consolidated technology like GPS (Global Positioning System). In addition, GPS signals do not perform well indoors. Therefore, alternatives have been developed for indoor positioning. The approach used in this work uses Bluetooth technology. Bluetooth networks have some advantages, such as low cost and a wide variety of compatible devices. The focus of this document is to add a new location possibility to the PreDetect API, originally designed to work with WiFi signal only.
