Example of cellular radius \(r_{j}\) for cellular tower \(\mathbf{c}_{j}\). Solid black lines outline the Voronoi tessellation of space, while the solid blue arrow denotes the cell radius \(r_{j}\). The dashed blue circle outlines the region whose radius is the cell radius \(r_{j}\). Because the region covers the estimated locations \(\hat{\mathbf{l}_{1}},\ldots , \hat{\mathbf{l}_{3}}\), the cell tower \(\mathbf{c}_{j}\) is a possible candidate for associating these estimated locations to actual cell towers
