Abstract :
The fifth-generation (5G) networks will provide high capacities with less transmission delays. To meet these
features, it is depicted that these networks must be densified that is with many base stations (BSs) dominated by small BSs.
The BS density to be deployed in a network is a vital design issue since an inappropriate BS deployment could give rise to
displeasing consequences, such as excess interferences, void cells that is cells without users, excess power consumption and
operating costs since over 50% of the total cellular network energy consumption is by BSs. In this paper, the simplex method
of linear programming is used to determine the optimal BS density that can consume the optimal power based on maximizing
the service area. Using the cell edge conditions, we generate radii of the two cells and hence respective areas are determined.
Results show that although all the minimum powers and their respective BSs cover the entire service area, there is an optimal
BS combination with an optimal power consumed.
