互联网接入中的数字公平通常是通过三个轴来衡量的：可用性、可负担性和采用率。大多数先前的工作侧重于可用性；其他两个方面受到的关注较少。在本文中，我们通过关注主要互联网服务提供商提供的宽带计划的性质来研究美国宽带的可负担性。为此，我们开发了一个宽带计划查询工具（BQT），它可以获得美国七个主要有线互联网服务提供商为美国任何街道地址提供的宽带计划（上传/下载速度和价格）。然后，我们使用这个工具来管理一个数据集，为这些互联网服务提供商查询30个城市超过837k个街道地址的宽带计划。我们使用计划的传输价值来比较计划，该价值定义为ISP以一美元的价格传输用户流量的Mbps。我们的分析提供了以下新的见解：(1)不同城市的ISP计划不同。具体来说，一个城市中多达60%的人口普查街区群体可以从ISP那里获得低传输价值计划；(2)城市内ISP规划具有空间集聚性，同一城市内的承载值差异可达600%；(3)当基于电缆的ISP与基于光纤的ISP在一个分组中竞争时，与单独运营或与基于dsl的ISP合作时相比，他们为用户提供的传输价值最高可提高30%；(4)光纤部署具有更好的传输值，与较高的平均收入街区群体相关。虽然我们希望我们的工具、数据集和目前形式的分析对不同级别（市、县、州）的政策制定者有所帮助，但它们只是量化数字不平等的一小步。最后，我们提出了进一步提高我们对宽带可负担性的理解的建议。
Digital equity in Internet access is often measured along three axes: availability, affordability, and adoption. Most prior work focuses on availability; the other two aspects have received less attention. In this paper, we study broadband affordability in the US by focusing on the nature of broadband plans offered by major ISPs. To this end, we develop a broadband plan querying tool (BQT) that obtains broadband plans (upload/download speed and price) offered by seven major wireline US ISPs for any street address in the US. We then use this tool to curate a dataset, querying broadband plans for over 837 k street addresses in thirty cities for these ISPs. We use a plan's carriage value, defined as the Mbps of a user's traffic that an ISP carries for one dollar, to compare plans. Our analysis provides us with the following new insights: (1) ISP plans vary inter-city. Specifically, up to 60% of the census block groups in a city can receive low carriage value plans from an ISP; (2) ISP plans intra-city are spatially clustered, and the carriage value can vary as much as 600% within a city; (3) Cable-based ISPs offer up to 30% higher carriage value to users when they are competing with fiber-based ISPs in a block group compared to when they are operating alone or in conjunction with a DSL-based ISP; and (4) Fiber deployments, which have better carriage values, are associated with higher average income block groups. While we hope our tool, dataset, and analysis in their current form are helpful for policymakers at different levels (city, county, state), they are only a small step toward quantifying digital inequity. We conclude with recommendations to further advance our understanding of broadband affordability.
