The multifocal cells problem: a case study on the telephonic network

In this thesis we are going to explore the problem of multifocal cells, i.e. telephonic cells that present an anomalous distribution in their geographical connection: users connect to those cells in positions distant from the repetitor of the cell and well distinct from each other with a high frequency, whilst it is expected that the signal degrades with the distance. \\ In this work we are going to describe a methodology to understand which cells have this problem using real world data and then we will analyze a possible solution for the positioning anomaly these cells create, using a data driven approach based on the creation of a repositioning algorithm in order to avoid errors in positioning due to the multifocality of the cell.
