“…This approach provides data transmissions using frequencies higher (a few tens kHz) than 50 Hz (or 60 Hz) related to the power supply. The PLCs are hampered by several factors: attenuation at the frequencies of interest [2,3]; noises [3][4][5][6]; interference due to electronic devices connected to the system [7]; crosscoupling interferences [8]. However, the PLC technology is characterized by several strengths [9]: it does not need additional wires for data transmission and allows maintaining the connections even in case of through walls and curvatures.…”

Power line communications (PLCs) refer to a technology based on the existing electrical wiring to transmit data among the devices connected to the network. The PLC technology is an excellent solution widely studied and analysed by researchers, even in those areas characterized by strict requirements, such as industries. In this paper, a technique based on fuzzy logic, for the dynamic management of the amplitude of the signal emitted by the devices of a power line network, is proposed. The main aim is to manage the amplitude of the transmission signal in order to reduce the noise introduced into the network, and, as a consequence, the power consumption, increasing data transmission quality of network in terms of Quality of Service (QoS). This solution has been implemented into embedded systems based on the ADD1010, a power line System on Chip (SoC), and tested through a real scenario realized in laboratory.
