Attempt to a Video-Transmission Capability in MV Mine Cable Network Using BPL-PLC Technology

This article presents and discusses the attempt to transmit video content using the BPL-PLC (Broadband over Power Line - Power Line Communication) technology. It includes simulation results of a specially developed digital transmitter and receiver, dedicated to a given predefined 6 kV mining power cable. The effect of two different transmission modes (2-7 MHz and 3-7.5 MHz) and two types of coupling (capacitive-inductive and induction-inductive), on the quality of bi-directional transmission, was also examined. The quality assessment of transmitted content, including both QoS (Quality of Service) and QoE (Quality of Experience) approaches, was evaluated on a set of samples processed in different resolution, namely: 480x270, 768x432, and 1280x720. Based on this, conclusions have been formulated, regarding the expected efficiency, as well as guidelines for further video transmission tests, including real-time mining conditions.
