Yo tambien espero que el PLC sea una auténtica revolución si solucionan los problemas de interferencias. Además, me parecería ofensivo que siendo española la que dicen es una de las mejores empresas diseñadoras de chips para modems plcs, DS2, tuviésemos que conformarnos con una plc cara y patética. Si es verdad que los modems con estos chips son los mas rapidos del mundo la oferta de ohio la pueden superar aqui en españa de goleada. Otra cosa son los intereses politicos o economicos que algunos desalmados puedan tener en la contencion a la hora de expandir estos servicios. Porque, iba Telefonica a permitir que endesa o iberdrola nos ofreciesen 1024Mbits por ejemplo a 20 euros? Está claro que hay un cierto corporativismo empresarial (pero no era ésto capitalismo?) que hace que no haya competencia a no ser que venga alguna empresa de fuera.
Sobre el tema seguro que os interesa leer ésto:

PLC service to 40% of Spain by 10/05
con algunas perlas como éstas:
"However they choose to move forward, the utilities have to get moving as the CMT has determined that these companies must offer service to at least 40% of their customers prior to October, 2005."
"The number of ADSL high speed internet connections in Spain is just over a million and a half as of the end of October, 2003. At 45 euros/month, ADSL in Spain is the most expensive and slowest in Europe, and is prohibitively expensive for many users. Inflated costs are being blamed on high last-mile access fees which are almost exclusively the domain of Spain’s ex-monopoly telecom operator Telefónica."
"The table Broadband Speeds and Costs demonstrates PLC’s role as a possible alternative from a social impact point of view for those regions which lack telecommunications infrastructure, but do have an electrical infrastructure".
"Iberdrola’s commercial PLC network contains technology and equipment based on the DS2 chipset and manufactured by the Japanese firm Toyocom. Tecnocom is a 'Global Preferred Partner' of Valencia-based DS2, leader in the development of high performance, low cost PLC chipsets and software.
DS2 is a fabless silicon design house and a leading supplier of silicon and software for PLC. The data rate of the DS2 chipsets is currently up to 45 Mbps (27 Mbps downstream and 18 Mbps upstream). 2 or 3 chips can be used in parallel to reach speeds up to 135 Mbps; new chipsets are in the works that will reach speeds of up to 100 Mbps"
"For its pilot tests in Barcelona, Seville, Santiago de Chile (Chile) and Zaragoza, Endesa used both ASCOM (Switzerland) and DS2.
For its pilot tests in Madrid, Toledo and Valencia, Iberdrola has used NAMS (Israel), ASCOM and DS2.
Union Fenosa used both Main.net (Israel) and DS2 for its pilot tests in Guadalajara and Madrid."
Perhaps for Spain and beyond, the most important long-term aspect of PLC is not better pricing and higher symmetrical transmission speeds, but the possibility for broadband services to be offered in areas where ADSL and cable services are not offered. As such, PLC will represent a giant step in the digitalization process of Spain and around the world
