【摘要】 提出了利用现有的有线电视网和电力线载波技术进行上网的一种接入方案。相对于AD-SL,有线电视网上网具有带宽宽,价格便宜,速度快的特点.有线电视网大部分是由混合光纤同轴电缆网(HFC)组成的,是单向的,需要进行双向改造。由于上行时的传输数据量很小,可利用电力线载波通讯的速率高,实现成本低的特点进行上传,从而提出了一种新的上网方式,下行利用HFC,上行利用电力线载波。更多还原

【Abstract】 In this article,a access project of web surfing with the existing CATV network and the PLC(power line carrier) technique is put forword.Relative to ADSL,web surfing with the CATV network has some characteristics,such as the bandwidth breadth,the price cheapness,the speed rapidness.The CATV network is mostly composed of hybrid fiber coax network(HFC),which is one-way,needs to carry on a bidirectional change.For upload’s data is little,the power line carrier communication can be made use of,which have high speed rate,low cost characteristics.Thus put forward a new wet surfing way,download to make use of HFC,upload to make use of the PLC.更多还原
