Broadband Radio

Ma Ju: single coaxial cable broadband access to both - two-way processing, broadband, radio and television - broadcasting industry
SARFT States Broadcasting President Ma Ju Institute of Science
One, the needs analysis first discuss the basic situation, the national television ownership in more than 500 million units, cable television 150 million net users, 47 million digital subscribers, So the digital cable TV is very important. For the development of cable networks have a lot of technology solutions at the same time, there are more companies and research institutes involved in the cable network to the next stage in development.

2 Current Situation and Strategies Examples are now widely used in the transformation of cable television network of some programs, with more HomePlugBPL, HomePlugAV, Wi-Fi down, HomePNA, modem cable, baseband EOC. Existence of these programs are reasonable, if the future will be, it does not.

Firstly, what we really dominant network, short board what I understand, the last of the cables wired network can not give up, whatever the point is that the band naturally. physical bandwidth of more than one G, the digital bandwidth of at least 7 G, the bandwidth of the future must not be discarded lightly, I want to give up radio and television is like our Unit brother, competitors, cooperation partners of the same thing was dry. Therefore, for the coaxial cable is concerned, use the cable modem high-availability technology is a mature technology. Although not very popular in China cablemodem institutional, political reasons, but whatever the stress cablemodem Shanghai and other cities in the success of this is to choose a major program in either direction for network transformation.

Second, MOCA, is indeed becoming more widely applied, but for us in terms of whether the direct reference to China more? For example, the bandwidth is appropriate and whether it meets our requirements, they are open to question and research. Aside from fiber to the home, the cable television network for the election is now the major energy cable modem. Now, many domestic firms EUC approach is proposed based on the access program, we Township ASTRI six years of this program is to promote their own broadband services, high performance network HiNOC system. Now, I will design ideas to share with you, please correct me criticism.

3 programs HiNOC technology systems and features
Firstly, there are several design points, the point of the design is first to the people what kind of business? In other words, the final of a meter or 10 meters how much bandwidth needs to be able to meet the needs of populations and the long-term future. After our analysis, given that many people in HD, SD, broadband Internet access and voice service possible, such as VoIP, triple play should be one-stop service. We believe there should be a threshold of bandwidth, we design is based on 30M, 40M mode, which is exclusive of bandwidth.

Secondly, we want to design a long-term future with the implementation of the network. There are many companies who are brothers and make their own programs, we think. Administration issued a White Paper, we have carefully analyzed, followed by two days before the meeting has been changed. Meets the needs of next generation, but also, and many businesses to communicate, communicate, so that the design concept and more bandwidth and business relationship must take into account is the system architecture and network architecture. We call the proposed content of the architecture based on IP, which makes our application on the IP layer, IP must be placed on our physical layer, which is our original intention and design.
