Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2016, Director: Eloi Puertas i Prats i Lluís Garrido OstermannWith the rising market of the BLE, we wanted to explore how it could be used for localization purposes, which could eventually be applied to study how people moves in a building, for indoor maps, or for a robotics project. The main goal of the project is to create an application that can localize a subject in an indoor environment, using BLE beacons as reference points. Our attempt is to achieve this goal by using beacons that will be built by us, which will use a radio frequency module that is not compatible with the BLE standard, but it is capable of "faking" certain type of BLE packets. This will give us a good knowledge about the BLE technology, get some experience working with beacons, and understand the location methods.
