Although the broadband network over electrical cable concept and solution has exsisted for years, believe it or not, an official international standard in this field does not exist. This is probably the reason we still connect over Ethernet and telephone cables.
However, this could all be coming to an end. A group working within the IEEE’s finally has given a final draft standard for broadband networking over electric power lines network. Before the standard would be accepted, there is a long process of making it finalized, but it is already known that the basic features offered are: speeds of 100 Mb/s, and that electric companies would very quickly accept it , and join the market as Internet service providers.
