当我们的布线厂商喋喋不休的讨论如何提高速度的六类、七类、八类方案时,其实都是一个误区,中国人还搞不清为什麽老外都不在自己的家里发展这些“先进的东西”?因为国外市场已经饱和,倒是中国的市场好蒙,大家被广告搞得搞不清了。其实网络的最好的传 输介质,还是同轴电缆,不费事就到很高的频率。现有的布线方案,其实是一个不断将就现有系统的一个找麻烦的系统,中国不应用他们的这个不得已而为之的产品。作为新发展的系统,完全可以用最好的新的方案,跳过去。只是可惜我的很多年前提这个方案的时候,还被讥笑,没有得到实施的机会。
告诉大家一个消息,同轴的布线系统MoCA即将要得到应用,这是老技术新的规划而已。就是我很多年前提这个方案。可以认为是现有布线系统的一场革命,可以为我们带来很多商机!!!我以后可以慢慢介绍,现先提供一段英文的文章参考。
About MoCA
The Multimedia over Coax Alliance (MoCA for short) has been formed as a non-profit mutual benefit corporation to develop and promote specifications for the transport of digital entertainment and information content over in-home coaxial cable.
The goal of MoCA is to create specifications and certify products that will tap into the vast amounts of unused bandwidth available on the in-home coax without the need for new connections, wiring, point of entry devices or truck rolls. It is anticipated that the first MoCA enabled products will be released within the next year.
More than 70% of homes in the United States have coax already installed into the home infrastructure. Many have existing coax in one or more primary entertainment consumption locations such as family rooms, media rooms and master bedrooms - ideal for deploying networks. MoCA technology allows homeowners to utilize this infrastructure as a networking system and to deliver other entertainment and information programming with high QoS.
The technology underlying MoCA provides the vital elements necessary to distribute DVD quality entertainment throughout the home - high speed (270 mbps), high quality of service (QoS), and the innate security of a shielded, wired connection combined with state of the art packet-level encryption. Coax is designed for carrying high bandwidth video. Today, it is regularly used to securely deliver millions of dollars of pay per view and premium video content on a daily basis. The MoCA network also can also be used as a backbone for multiple wireless access points used to extend the reach of wireless throughout a consumer's entire home |
