In Europe, the Valeo component manufacturer and the company manufactur-

ing PLC products worked together to implement a solution using PLC to communi-

cate the information from the vehicle sensors to the instrument panel.

This type of PLC network can also be used to broadcast external camera or

onboard DVD drive videos.

Economic Perspectives

As we have seen in this chapter, most applications transported by the electrical net-

works face multiple constraints inherent in PLC (i.e., bit rate, topology, and also

number of users in the network).

The number of these applications goes on increasing, but most of them are

already available in the conventional networks, like voice or video.

The number of PLC terminals also constantly increases, and nowadays PLC

products can be found with most resellers of data processing and network equip-

ment.

Therefore, PLC must be considered not only as a network technology but also

as a simple means to connect devices together by allowing information sharing. The

emergence of PLC in the hi-fi world is a striking example of this. A central server

connected to the Internet can deliver any type of flow (video or audio) to any device

(LCD screen or mini-system) located in the house by means of PLC links.

Therefore, the economic perspectives for PLC networks are high, in particular

for the following reasons:

•

Emergence of HomePlug AV products in the course of 2009.

•

Commitment of Internet access providers to widen the distribution of

InternetBox services to housing. In the long run, this strategy will generalize

the use of PLCs among the general public.

•

Growing understanding by the general public of a technology that is now

mature and particularly simple to use (no new wiring, use of existing outlets,

simplified configuration, security, and so forth).

•

Understanding by professionals that PLC networks complete cables and

Wi-Fi, in particular with the development of PLC products dedicated to the

requirements related to the administration and management of professional

networks.

Figure 6.10 illustrates the expected growth of PLC networks by 2010. Its easy

deployment combined with lower costs for the devices and the development of

products combining several technologies (gateway, router, modem, firewall, server,

and so forth) undoubtedly ensure that this technology has a great future ahead.
