}Abstract:
Power line communication (PLC) systems consist of a technology that uses existing electrical power systems as a communication medium to enable data transmission over power lines, whereas the main task of the power lines is the delivery of AC at a specific frequency (50 Hz). This research report describes the protocol used for the transmission of information in a narrow-band conveyed wave system for home automation applications and the related experiment-based delay analysis and performance evaluation. In particular, the analysis focuses on the operation of the system in a specific band, which belongs to the field of application of the CEI EN 50065-1 standard (identical according to CENELEC EN 50065-1: 2011-04), which is entitled "Transmission of signals on low voltage electrical networks in the frequency range from 3 to 148.5 kHz" and, more precisely, we refer to the C band which includes the frequencies from 125 kHz to 140 kHz. This frequency band is used for systems that work in time sharing or burst and therefore do not continuously occupy the channel. Furthermore, a carrier sense multiple access with collision avoidance (CSMA/CA) protocol for carrier transmission that operates in the medium access control (MAC) layer is used to facilitate the coexistence of multiple systems in the same network and guarantee their interoperability in the same frequency band. In addition, two alternative architectures have been proposed for integrating the system with wireless technologies, in particular by extending the network by means of access points or via an ad-hoc network.
