The electrical network construction rules determine the PLC engineering to be
implemented to obtain the best coverage and the best performance of the IP network
to the subscribers and the outlets of the community buildings.
Figure 12.7 illustrates an electrical network representative of a community from
the MV/LV transformer to the various branches of the LV (low voltage) network
supplying the subscribers’ meters.
If we take a closer look at the topology and the electrical devices of a power line
distribution system in a dense urban environment (dwelling meters supply, for
example), we find again the situation illustrated in Figure 12.8. This very complete
Figureure shows the various components of the electrical network from the local
electrical substation to the meter in an apartment. The PLC devices used for broad-
casting the data signal from the electrical substation to the slave PLC device in the
apartment are superimposed on this electrical installation.
Implementation of a Communitywide PLC Network
Various issues must be considered when installing a PLC network for a community.
To begin with, a project team is set up, with a contracting authority (in this case, the
community defining the requirements in terms of Internet access and IP network in
order to prepare the specifications) and a prime contractor defining the engineering
