Abstract:

Production processes coming up with Industry 4.0 will demand a high degree of flexibility since customers request more individual products. Employing wireless communication is a key enabler to meet these requirements. In order to deploy wireless systems for emerging industrial use cases in a way that both low latency as well as high reliability is guaranteed, knowledge about the radio channel is crucial. This requires representative channel measurements considering a specific use case. With this in mind, we propose a novel channel measurement approach representing industrial Device-to-Device (D2D) communication between moving Automated Guided Vehicles (AGVs), and present the obtained results. We study how obstacles affect the channel by modifying the test environment with metallic obstacles. For reproducibility, we automate the movement during the measurements using an AGV. We capture impulse responses each millisecond to resolve the time variation of the channel. It turns out that even under Non-Line-of-Sight (NLOS) conditions, the loss of receive power over the whole bandwidth is moderate due to a large number of reflections. We conclude that exploiting frequency and spatial diversity is a promising way to improve the communication reliability in industrial scenarios. We also infer that modeling the time-varying nature of channel parameters in industrial environments is feasible based on measurement data.
