Executive Summary

In the last two decades, a remarkable research effort has been put in PLC systems. These systems cover three main applications: access, the use of the low voltage power network as a last mile solution; indoors, the use of power grids inside small offices and homes as support for local area networks and in-vehicle, the use of on-board power grid for control and data transmission purposes. Now-a-days, it is the second one that attracts more commercial interest, at least in the developed countries. In particular, this technology is very appropriate for the triple play service, i.e., to distribute telephone, internet access and digital video (that are provided by means of ADSL or cable) inside the consumer premises.
