Estudio del estándar “Bluetooth 5”

Abstract

Bluetooth is an open, short-range and low power Wireless Network Bluetooth, which aims to simplify communication between devices of different technology and facilitate the transmission of information through a radio frequency link. Bluetooth has five versions, divided into two main modes of operation, Classic Bluetooth and Bluetooth Low Energy (BLE). BLE is designed for the use of IoT applications. In the last version of Bluetooth, Bluetooth 5 improves all its features with the aim of surpassing other technologies that want to be the base of communications for IoT. Bluetooth 5 highlights its greater range, higher data transmission speed, improved support for advertising and energy efficiency. The new mesh topology feature makes Bluetooth a serious candidate for IoT communications since it allows the implementation of decentralized architectures. In this work a revision and comparison of the Bluetooth versions is carried out, deepening in version 5. On the other hand, the operating requirements of the IoT, based on the recommendations of ITU are reviewed. The contribution of this work is the analysis of the characteristics of Bluetooth 5 to determine whether or not they meet the IoT requirements proposed by the ITU.
