近一时期对于互联网和电子商务不断增长的需求所提供的低成本的宽带基本结构和互联网的连通引起人们极大的关注。但是,低成本的宽带连通到户的可行性,确实没有引起人们极大的关注。所以,称之为“最后的路段”。对最初的两部分特性,PETER BRANAGAN(RTE)讨论了如何让具有无线返回通路的数字地面电视(Digital Terrestrial Television,DTT)拥有其需要可能提供的极低成本的解决方案。 In recent times, the low-cost broadband infrastructure and the connectivity provided by the Internet for the ever-growing demand for the Internet and e-commerce have drawn great attention. However, the feasibility of connecting low-cost broadband to households has really failed to attract the attention of people. So, call it “the last section.” For the first two parts, PETER BRANAGAN (RTE) discusses how to get a Digital Terrestrial Television (DTT) with a wireless return path with an extremely low cost solution that it may need.
