Developing ways to affordably deliver broadband connectivity is one of the major issues of our time. In challenging deployment locations with irregular terrain, fiber optic or traditional Clear-Line-Of-Sight (CLOS) wireless links can be uneconomical to deploy, resulting from the number of required towers making infrastructure deployment unviable. With the emergence of new research focusing on developing wireless diffractive backhaul technologies to provide diffractive Non-Line-Of-Sight (NLOS) links, this paper evaluates the engineering-economic implications of such approaches. To quantify different technology strategies, a Three-Dimensional (3D) techno-economic assessment framework is presented to help prioritize regions for future investment in broadband connectivity, utilizing a combination of remote sensing and viewshed geospatial techniques. Such a method is an essential evaluation step prior to beginning detailed Radio Frequency (RF) Quality of Service engineering but has hitherto received less research attention in the literature. This framework is applied to assess both Clear-Line-Of-Sight and diffractive Non-Line-Of-Sight strategies for deployment in Peru, as well as the islands of Kalimantan and Papua, in Indonesia. The results find that a hybrid strategy combining the use of Clear-Line-Of-Sight and diffractive Non-Line-Of-Sight links produces a 15-43 percent cost-efficiency saving, relative to only using traditional Clear-Line-Of-Sight wireless backhaul links. The codebase is released opensource via the Engineering-Economic Evaluation of Non-Line-of-Sight Backhaul (e3nb) repository.

衍射非视距回程 (e3nb) 的工程经济评估:3D 无线回程评估的技术经济模型

开发以经济实惠的方式提供宽带连接的方法是我们这个时代的主要问题之一。在具有不规则地形的具有挑战性的部署地点,光纤或传统的视线清晰 (CLOS) 无线链路的部署可能不经济,因为所需的塔数量众多,导致基础设施部署不可行。随着专注于开发无线衍射回程技术以提供衍射非视距 (NLOS) 链路的新研究的出现,本文评估了此类方法的工程经济影响。为了量化不同的技术战略,提出了一个三维 (3D) 技术经济评估框架,利用遥感和视域地理空间技术的组合,帮助确定未来宽带连接投资的优先区域。这种方法是开始详细的射频 (RF) 服务质量工程之前必不可少的评估步骤,但迄今为止在文献中受到的研究关注较少。该框架适用于评估在秘鲁以及印度尼西亚的加里曼丹岛和巴布亚岛部署的清晰视线和衍射非视线策略。结果发现,相较于仅使用传统的 Clear-Line-Of- 链路,结合使用 Clear-Line-Of-Sight 和衍射 Non-Line-Of-Sight 链路的混合策略可节省 15-43% 的成本效率。视线无线回程链路。该代码库是通过非视距回程 (e3nb) 存储库的工程经济评估开源发布的。
