对于运营商来说,为了应对皮飞站的大规模部署和用户日益增长的有线接入速率需求,充分利用好PON和4G 的各自优势,建立PON+LTE的融合宽带网络,实现优势互补,可为用户提供体验一致的高速宽带接入服务。文章详细分析了在NG-PON2中将LTE小基站信号和高速有线宽带信号混传的技术。仿真结果显示,在NG-PON2的备选技术-正交频分复用无源光接入网(OFDM-PON)中混传无线LTE信号和高速有线宽带信号可以省去无线信号的上下变频处理,技术实现简单,可以提升接入信号的多样性和速率。

Research on heterogeneous access technique of LTE and wired broadband signals based on NG-PON2

For telecommunications operators, making full use of the advantages of PON and 4G respectively, can construct a converged broadband network and provide high-speed broadband access services to users. In order to meet the large-scale deployment of 4G small stations and the increasing demand for wired access speed, the heterogeneous access technology of LTE signals and high-speed wired broadband signals in NG-PON2 was analyzed in this paper. The simulation results show that the orthogonal frequency division multiplexing PON (OFDM-PON, NG-PON2 alternative technology) with hybrid LTE signal and high-speed wired broadband signal can omit the wireless signal up and down frequency conversion processing and improve the access signal diversity and rate.
