Summary

Descripción general del contenido del recurso.

Abstract This study examines the characteristics of the lowvoltage MIMO-PLC electric power line channel, which operates within the 2-100 MHz frequency range. The research involved measurements in four different Setups using 2.5 mm copper wires, including phase, neutral, and protective earth wires. These wires were transposed within a conduit, measured in pairs, with variations in the number and lengths of branches, assuming a deterministic modeling behavior of the electric power line. Throughout the experimentation process, essential parameters such as the magnitude of the S21 scattering parameters and VSWR identify frequency ranges suitable for efficient data transmission. The findings suggest remarkable prospects for enhancing PLC communication across MIMO channels. Depending on the combination of cable lines, over 70% of the bandwidth remains available. Additionally, the overall average impedance measured at 77.14 Ω is vital for impedance matching in PLC coupling circuit designs.
