Novel Heuristics for Cell Radius Determination in WCDMA Systems and Their Application to Strategic Planning Studies

The authors propose and compare three novel heuristics for the calculation of the optimal cell radius in mobile networks based on Wide-band Code Division Multiple Access (WCDMA) technology. The proposed heuristics solve the problem of the load assignment and cellular radius calculation. They have tested their approaches with experiments in multi-services scenarios showing that the proposed heuristics maximize the cell radius, providing the optimum load factor assignment. The main application of these algorithms is strategic planning studies, where an estimation of the number of Nodes B of the mobile operator, at a national level, is required for economic analysis.
