Abstract
Bluetooth is an open, short-range, and low power Wireless technology, which aims to simplify communication between different kinds of devices. Bluetooth has five versions, divided into two main operation modes, Classic Bluetooth and Bluetooth Low Energy (BLE). BLE is designed for the use of IoT (Internet of Things) applications. The fifth version of Bluetooth improves all the features to surpass other technologies that want to be the base of IoT communications. Bluetooth 5 achieves greater range, higher data transmission speed, improved support for advertising, and energy efficiency than previous versions. The new mesh topology feature makes Bluetooth a good candidate for IoT communications since it allows decentralized architectures. In this work, a revision of the Bluetooth version 5 is carried out. Furthermore, the IoT's operating requirements, based on the recommendations of ITU (International Telecommunication Union), are presented. 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. The analysis results indicate that Bluetooth 5 meets the high-level requirements and approximately half of each category's standard IoT requirements.
