Estudio comparativo del posicionamiento indoor con tecnologías Wi-Fi y Bluetooth para la Facultad de Informática y Electrónica.

Abstract

A study and analysis of the most important parameters of the Wi-Fi network implemented at the Informatics and Electronics Faculty was carried out in order to establish the comparison regarding to indoor positioning with a network Bluetooth prototype built on Arduino UNO plates and HC-05 Bluetooth modules. The different models of location of central equipment in the indoor positioning were investigated and the calculation was developed for the hexagonal mosaic model that was selected as the most convenient in terms of costs and performance. The location techniques and algorithms were also researched; these must be taken into account to develop a real-time positioning system. For the Wi-Fi network analysis it was necessary to monitor the networks with a software called “acrylic Wi-Fi” which identifies and displays information like reception intensity, MAC Address, channels and receipted networks speed at any point. In addition a Wi-Fi network prototype was implemented in order to carry out a coverage analysis in the areas were the networks from the installed equipment were not received for the study area at Informatics and Electronics Faculty. The Bluetooth network was basically implemented with a Master-slave connection that makes use of an indicator to verify the established connection. From the Wi-Fi network monitoring in places with good and bad signal reception, the repositioning and installation of certain equipment which might cover the poor signal reception in the professor´s room is proposed, this will not result in great expenses since there is an existing Wi- Fi network implemented and administered by the Communication and Information Technology Department (D-TIC). Finally, the use of Bluetooth technology for indoor positioning at the Informatics and Electronics Faculty (FIE) is discarded because in comparison with Wi-Fi technology, it must be implemented from the beginning and it does not have any control system at the Communication and Information Technology Department that allows the users administering the system with this technology.
