Abstract
Recent improvements in embedded device hardware have led to increased performance and energy-efficiency, enabling the development of new low-power Industrial IoT (IIoT) solutions. When it comes to the development of energy efficient industrial systems, the most commonly used options are Low Power Wide Area Networks (LPWAN) technologies. However, these sub-Gigahertz technologies are often limited in terms of transmission due to duty cycle, so they are not a viable option when it comes to sending constant data flows in real time. The 2.4 GHz band is an option for these cases and, for power-constrained devices, Bluetooth is a reference technology in terms of low power consumption. Nevertheless, communications have frequently a short range, so it is usually difficult to use it in IIoT harsh scenarios. To tackle these issues, the new Bluetooth 5 standard introduces a new transmission mode (Bluetooth 5 LE Coded) that allows a longer range, thus improving the link budget and providing an increase of the sensitivity. In this paper, we analyze the power consumption, transmission times and range of a real-time IIoT system developed on Bluetooth 5, comparing its results with the Bluetooth Legacy version. For this purpose, several tests were carried out with different configuration parameters and in different transmission modes. The performed experiments allow for concluding that LE Coded offers significant advantages respect to Legacy with similar power consumption.
