Distribution networks. Used for connecting the exchanges of the Internet

access providers and the subscribers to the Internet and to IP networks in gen-

eral. These networks consists of all the media that can be used to reach the

subscribers located at a few kilometers of the Internet access providers’

exchanges. PLC technologies are undeniably ideal for distribution networks

insofar as the topology of the electrical networks makes it possible to reach all

the buildings and potentially each outlet of a community building.

•

Local area networks (LAN or interbuilding network). Usually Ethernet or

Wi-Fi, they are likely to be replaced or completed by the PLC technology with

non-negligible advantages (throughput, security, easy deployment, pervasive

presence of outlets).

The issue with a community illustrated in this chapter is to build a distribution

network using PLC technologies or according to a hybrid architecture combining

several technologies making it possible to provide a high throughput Internet access

to all the buildings of the community.

Figure 12.9 illustrates this telecommunications networks pyramid in which

PLC technologies can place themselves at the level of LAN and distribution net-

works in the case of communities.
