Advanced planning techniques for cellular systems in metropolitan areas

The increasing traffic demand of mobile radio system forces the operators to reduce cell sizes. This implies that planning efforts are increased, due to the larger number of cell sites as well as to the greater sensitivity of propagation to local factors, such as building layout, street width, presence of vegetation and of man-made structures, etc. One solution to the above problems is given by self-adapting planning procedures. In this paper we present one planning method of this kind, based on a well known dynamic channel assignment method, i.e., channel segregation. It has been applied to both a microcellular and a small-cell environment. Simulation results are encouraging in both cases
