FTTH与TD-LTE在农村部署的投资对比

Comparison of investment between FTTH and TD-LTE launched in rural areas

本文首先给出了FTTH和TD-LTE在农村宽带部署的两种接入模型,针对农村复杂地形地貌抽象出了大村模型和小村模型。具体细化了FTTH和TD-LTE在农村部署时的成本因素,提出了FTTH和TD-LTE的投资模型。分别在大村模型和小村模型下,对FTTH和TD-LTE的单用户投资进行了比较。在大村模型下,FTTH接入模型投资小于TD-LTE;而在小村且人口稠密的地方,TD-LTE接入模型投资小于FTTH。

Firstly, the paper provides FTTH access model and TD-LTE access model launched in rural areas. The big village model and the small village model are abstracted out according to the complexity of rural. The investment models of FTTH access and TD-LTE access are presented by considering the cost factor of specific details launched in rural areas. Single user investments under two investment models are compared respectively between big village model and small village model. The results show that investment of FTTH access model is less than TD-LTE in big village, while investment of TD-LTE access model is less than FTTH in small village in a densely populated.
