CHAPTER 11

PLC for Businesses

The PLC networks increasingly invade the business world, and more generally the

networks of professional and industrial buildings, where they complete or replace

Wi-Fi or Ethernet networks.

The PLC networks can be considered as backbones not only for the premises of

a SMB but also for professional (hotels, hospitals, concert halls, superstores, and so

forth) and industrial (factories, warehouses, cranes, and so forth) buildings due to

the performance and propagation distances of the electrical networks.

Therefore, the PLC networks can be considered as a technology used for replac-

ing, completing, or serving other corporate network technologies, in particular the

following ones:

•

Backbone to replace the Ethernet network for cost reasons or for buildings in

which works cannot be carried out (classified or protected buildings, hospi-

tals, and so forth) or backbone of a Wi-Fi network to connect the various cells

of the radio system;

•

Supplement to the Ethernet network to satisfy the needs for the extension of

an existing network (lower costs, easy deployment, and so forth) or if a com-

pany moves;

•

Temporary network for event coverage (such as a concert, conference, and so

forth);

•

Creation of several distinct networks on the same electrical network (adminis-

tration, public corporation, laboratory, and so forth).

The price of PLC devices is not very high, especially in the case of a company

fully changing over to the PLC technology when reasoning in the long term and if

the savings related to the wired equipment are considered (cables, outlets, switches,

and so forth).

Within a company, the PLC network can be considered either as an operating

network or as a “guest” network used, for example, by visitors for gaining access to

the Internet. In the latter case, it is preferable to separate this network from the cor-

porate network.

As in the previous chapter devoted to the installation of a PLC home network,

this chapter describes the necessary steps for the installation and configuration of a

PLC corporate network with special emphasis on access to the electrical network.
