Wireless Network Coverage in the Wild: A Multi-City Multi-Operator Data Set

It is a large-scale data set of wireless network coverage for over 22,000 4G base stations in France. This data set is generated by applying VoronoiBoost and official sources of base station deployment. The data covers ten main metropolitan areas in the country, encompassing a variety of dense urban, suburban and rural areas. The coverage information in each area is reported separately for the four major mobile network operators active in France.Coverage is represented as a set of polygonal shapefiles for each base station in the data set, each associated with a given probability that end terminals associated with the base station are located within the polygon (see image). The data set substantially improves current practices for cellular coverage representation in large-scale studies, which primarily rely on plain Voronoi tessellations of the geographical space. As such, the data set can support data-driven networking research where coverage overlap or interference are vital factors and multidisciplinary investigations based on network metadata that needs to be mapped on the territory.本数据集系针对法国境内超过22,000个4G基站无线网络覆盖的大型数据集。该数据集通过VoronoiBoost算法及官方基站部署资料生成。数据范围涵盖该国十个主要大都市区域，包括各类密集城区、郊区和乡村地区。每个区域的覆盖信息均针对法国境内活跃的四大移动网络运营商分别进行报告。覆盖范围以数据集中每个基站所关联的多边形形状文件集进行表示，每个多边形均附带一个特定概率，用以指示与基站关联的终端设备位于多边形内的可能性（见图示）。该数据集显著提升了大规模研究中蜂窝网络覆盖表示的现有实践，这些实践主要依赖于地理空间的简单Voronoi划分。因此，该数据集能够支持以覆盖重叠或干扰为关键因素的驱动型网络研究，以及基于需在领土上映射的网络元数据的跨学科调查。
