Reliability Evaluation of Bluetooth Low Energy for Industry 4.0
Víctor Díez, Aitor Arriola, Iñaki Val, Manuel Maria Velez · 2019
The reliability of a point-to-point link for Industrial Wireless Sensor and Actuator Networks (IWSANs) is evaluated in this paper. The point-to-point link is based on the physical layers (PHYs) 1M and 2M of Bluetooth Low Energy (BLE). Both PHYs are tested under different wireless channels: additive white Gaussian noise (AWGN), Rician, Rayleigh, and the IEEE 802.15.4a CM8 industrial channel. The packet error rate (PER) is the metric used to evaluate the reliability. Results are presented and compared with the requirements of typical industrial use cases.
