大量经济研究表明，宽带连接与经济生产率之间存在很强的相关性。这些发现促使美国联邦通信委员会等政府机构向服务提供商提供激励，鼓励他们在未得到服务或服务不足的地区部署宽带基础设施。在本文中，我们描述了一个确定网络基础设施部署目标区域的框架。我们的方法考虑了(I)基础设施可用性、(Ii)用户人口统计和(Iii)部署成本。我们使用多目标优化来确定哪些地理区域拥有最大的未得到/未得到充分服务的用户，并且可以以最低成本进行升级。为了证明我们框架的有效性，我们考虑了来自美国的有形基础设施和人口数据以及两种不同的部署成本模型。我们的结果确定了从成本和影响的角度来看，将是宽带部署的有吸引力的目标的国家名单。最后，我们讨论了我们框架的影响和更广泛的应用。
A large body of economic research has shown the strong correlation between broadband connectivity and economic productivity. These findings motivate government agencies such as the FCC in the US to provide incentives to services providers to deploy broadband infrastructure in unserved or underserved areas. In this paper, we describe a framework for identifying target areas for network infrastructure deployment. Our approach considers (i) infrastructure availability, (ii) user demographics, and (iii) deployment costs. We use multi-objective optimization to identify geographic areas that have the largest concentrations of un/underserved users and that can be upgraded at the lowest cost. To demonstrate the efficacy of our framework, we consider physical infrastructure and demographic data from the US and two different deployment cost models. Our results identify a list of counties that would be attractive targets for broadband deployment from both cost and impact perspectives. We conclude with discussion on the implications and broader applications of our framework.
