Introduction
The advantages in the implementation of a communication network using the same
electrical network that supplies all the elements of the network are evident. In the presence
of new wideband LANs using an RF system, for example Bluetooth, a narrowband
communication system using the mains has considerable advantages also.
It is widely accepted that in residential or industrial areas, in parallel to a wideband network
for audio/video streaming and Internet, having a narrowband LAN is useful to carry simple
information such as measurements, commands to actuators, system controls and so on.
Many applications can be covered by a narrowband communication system in a residential
structure, outside the house or in industrial applications (see Figure 1 below).
Figure 1. Typical powerline modem applications scenario
For example in houses or commercial buildings possible applications are power
management, lighting control, heating or cooling system management, remote control of
appliances (by internet or telephone), and control of alarm systems.
Considering external applications, the main areas concern communication with meters, in
particular automatic measuring and remote control, prepaid supply systems, meter or in-
home remote displays. Another relevant industrial segment could be street lighting
management.
