www.DS2.esLaunch Event and Demos in New York City next month, November 2007
18th October 2007, Valencia, SPAIN - DS2 announced today that it has developed technology that will allow next generation powerline products to operate at a peak data rate of 400Mbps. This milestone will enable the development of new HD-capable multimedia applications, such as multi-channel HD-IPTV delivery or multi-room PVR.
Demonstrations of the 400 Mbps powerline technology will be featured at the invitation only technology launch in New York City next month. DS2 400Mbps technology will be available in next generation products from DS2 on time to satisfy the demands for extra bandwidth in the digital home and last mile applications that most analysts predict will happen from 2009 onwards. Next generation multimedia applications including multi-room IPTV and HDTV networked entertainment services, networked PVRs (personal video recorders) and multiple video streams will require bandwidth sufficient to support 5 or more simultaneous video streams.
A recent study from the Diffusion Group on ”Bandwidth Challenges to the Digital Home” (2007), confirmed that the need for bandwidth sufficient to deliver at least 3 HDTV and 2 SDTV streams to the home is foreseen as early as 2009.
DS2’s 400 Mbps technology will be compatible with existing 200Mbps products from DS2, ensuring a seamless migration path for existing users and designs, and will comply with the evolving standards. This quantum leap in performance is slated for 2009.
Jose Calero, CTO at DS2 stated, “Increased bandwidth requirements for multimedia networking applications is one of the key requirements that suppliers to the home networking, networked entertainment and last-mile BPL markets are looking for from future technology specifications. We are well on the way to developing our 3rd generation technology to ensure that suppliers will have the products available to meet the demand for multimedia applications in the future. These results are very exciting and demonstrate that we will be able to achieve the rates required to sustain the multimedia applications of the future over powerline or coax”.
The new technology builds on the success of DS2’s 200 Mbps technology, already deployed and tested by leading operators that include Belgacom, British Telecom, Portugal Telecom, Telefonica, Telecom Italia and Telia Sonera; global electricity utilities such as Endesa, Electricite de France, and Iberdrola and vendors of networking products including Buffalo, D-Link, Comtrend, Corinex Communications and Netgear. During 2008 DS2´s roadmap includes the delivery of additional features in the 200 Mbps technology, as well as reducing manufacturing costs, to give DS2 the edge in meeting customer demand for increased customization of today’s powerline enabled multimedia applications.
DS2 will continue to maintain its low-cost leadership with this 400 Mbps generation as well.

FCC: NTIA REPORT CONFIRMS FCC BPL RULES ARE EFFECTIVE

This month, the National Telecommunications and Information Administration (NTIA) released its BPL Phase II report, which generally confirms that the FCC technical rules do protect federal government operations from harmful interference. NTIA used NEC modeling to predict the RF emissions from BPL systems, and concluded that "the peak field strength seen in close proximity to a BPL-energized overhead power line will occur at various heights, and often near the height of the power line." Furthermore, NTIA concluded that measurements of the 80th percentile of emissions from BPL systems effectively estimate their true interference potential, thereby eliminating localized peaks that are "unlikely to be encountered by a radio receiver randomly located in close proximity to an Access BPL power line." Finally, the NTIA report affirmed the accuracy of using a 5 dB correction factor to measure BPL emissions above 30 MHz when measuring at a height of 1 meter above ground. It also generally affirmed the accuracy of the FCC's extrapolation factor for measuring emissions at distances different from those prescribed by the emission limits. While it did find that the FCC extrapolation factor may underestimate emissions below 6 MHz, the extrapolation factor "show[ed] good agreement" with the rate that NTIA estimated that field strength actually decays generally below 30 MHz. In response, the FCC sent a copy of the NTIA Phase II report to the U.S. Court of Appeals for the District of Columbia, which will hear oral arguments this month in the ARRL's appeal of the FCC's BPL technical rules. The FCC told the court that the NTIA report supports the FCC's findings in its Report and Order that the interference potential from BPL is low and that the NTIA's findings are consistent with the FCC's extrapolation factor, which the ARRL challenges on appeal. The NTIA Phase II report also helps to rebut a recent report by NATO, which expressed concerns about BPL interference to military operations.
