This paper presents a new quantitative method to measure how cellular areal network coverage is distributed over a country or region, specifically focusing on the extent to which coverage is concentrated in urban centers versus rural areas. We introduce the Cellular Coverage Inequality (CCI) index, a novel metric for assessing the equality of network distribution from a geographic perspective. The index is derived from rurality maps essentially generated from population data and operator reported cellular coverage maps. Beyond serving as a diagnostic measurement, we propose the CCI index as a regulatory tool designed to bridge the urban-rural divide. By establishing quantifiable equality benchmarks, the CCI index enables authorities to guide network evolution toward more equitable outcomes. Furthermore, the index serves as a strategic planning instrument for operators, allowing them to utilize changes in CCI to predict and quantify how specific infrastructure investments will impact regional equality. We demonstrate the utility of the CCI index by analyzing the official regulatory coverage maps of Sweden (2013–2020) and France (2019–2025).

Persistent rural–urban disparities in broadband connectivity remain a major policy challenge, even in digitally advanced countries. This paper examines how these inequalities manifest in northern Finland and Sweden, where sparse populations, long distances, and seasonal variations in demand create persistent gaps in service quality and reliability. Drawing on survey data (n = 148), field interviews, and spatial analysis, the study documents how variability in connectivity shapes everyday life and work in Arctic rural communities.

To assess these disparities more systematically, the paper applies the Cellular Coverage Inequality (CCI) index as a spatial Key Performance Indicator (KPI). By relating mobile coverage outcomes to degrees of rurality, the CCI highlights how network performance is unevenly distributed across space and reveals disparities that population-based or aggregate coverage statistics often obscure. While headline indicators suggest high levels of availability, experiential evidence points to recurring reliability constraints and location-specific coverage gaps affecting safety, work practices, and access to essential services.

Building on these findings, the paper develops policy reflections in six areas: shared infras- tructure and roaming frameworks, spectrum flexibility and local access models, performance- based Quality-of-Service monitoring, standardized and transparent reporting, techno-economic and environmental constraints of rural deployment, and digital-skills initiatives. Together, these reflections underscore the importance of combining spatial performance metrics with gover- nance and cost considerations when evaluating broadband policy in sparsely populated regions. The study contributes to ongoing debates on how connectivity monitoring can move beyond nominal coverage targets toward more equitable and performance-sensitive policy frameworks.
