 CHAPTER-1
                                           INTRODUCTION 
 1.1   INTRODUCTION
           
 The National Communications System (NCS) was established through a Presidential   Memorandum signed by President John Kennedy on August 21, 1963.  The memorandum assigned the NCS the responsibility of providing necessary communications for the   Federal Government under national emergency conditions by linking togethe improving, and expanding the communication capabilities of the various agencies.

 In April 1984, President Ronald Reagan signed Executive Order (E.O.) 12472, Assignment of National Security and Emergency Preparedness (NS/EP)  Telecommunications Functions,ii which broadened the mission and focus.  Since that  time, the NCS has been assisting the President and the Executive Office of the President  (EOP) in exercising wartime and non-wartime emergency telecommunications and in   coordinating the planning for, and provisioning of, NS/EP communications for the Federal Government under all circumstances.  In this regard, the Office of the Manager,   the NCS (OMNCS) continually seeks to improve the Federal Government's ability to respond to the telecommunications requirements to support national security and emergency situations.  Among these responsibilities, the NCS seeks to ensure that a national telecommunications infrastructure is developed that “is capable of satisfying  priority telecommunications requirements under all circumstances.”The OMNCS is the appropriate body to communicate NS/EP requirements to standards bodies and participate in related standards activities.


1.1.1 GOALS
            The goals of this TIB are to:
·        Present a brief introduction to BPL technology
·         Identify the potential benefits of BPL for NS/EP applications in support of Critical  Infrastructure Protection (CIP) requirements
·        Describe technical issues related to BPL for NS/EP
·         Identify areas for further development of the technology that would enhance the
government’s NS/EP mission performance capabilities
 This TIB is intended to provide technical, administrative, and other information pertaining to BPL technology for consideration by the agency members of the NCS.   BPL technology has a variety of names around the world including:  Power Line  Telecommunications (PLT), Power Line Communications (PLC) and others.  consistency, even when material from foreign countries is referenced, BPL is applied  throughout this TIB. 

1.2    BACKGROND
             
According to the Institute for Electronic and Electrical Engineers (IEEE)iv and the International Telecommunications Union  (ITU) the United States is lagging behind other countries in the deployment of broadband telecommunications networks. In December 2005 the ITU documented (see Figure 1.1) that among the top 20  worldwide economies, US broadband deployment ranks in the bottom 20%.  In the US, broadband services to the home are  largely provided by cable modems and digital subscriber loop (DSL) services. 


CHAPTER-3
        CONCLUSION

            The next few years will decide whether BPL can compete in the broadband market. The quantity of research in the field has resulted in the solutions outlined above. These solutions are the foundation for making BPL viable. But even if it is technologically viable, will it be economically viable .BPL offers a method of broadband access for those living in isolated areas, who have no other viable means of broadband access. Therefore, it seems plausible that when BPL will become available in rural areas, it will be a moderate success. However, this success is unlikely to be long-term, since telecommunications companies are already contemplating rolling out FTTH (Fibre to the Home) connections to all of their customers sometime in the future. Therefore, it appears that BPL will be little more than a stopgap solution.
