Field techniques to overcome aggressive noise situations in PLC networks

Power Line Communications (PLC) technologies and systems use state-of-the-art technical solutions to provide communication means for Smart Grid applications. PRIME is one of those systems, with a comprehensive Physical and Media Access Control (MAC) Layer specification for CENELEC A-band, used today in Smart Metering deployments. PRIME systems have demonstrated to be capable of working in normal scenarios (urban, suburban and rural) covering long distances in typical noise conditions. However, there are locations where noise is harsher than the regular conditions. This kind of noise is usually found close to the premises where meters are located. It often shows a periodic nature, both in its origin and external effects (e.g. daytime and nighttime cycles). This paper proposes a way to overcome the noise situation mentioned above, based on field deployable solutions. These solutions are based on the development of devices which, using the switching concept inherent to PRIME systems, can help affected meters to overcome noisy situations. Results from field experiments are provided, and the conclusions may be used to further develop products to overcome aggressive noise situations on field.
