In recent years, new mobile communication services, such as downloading movies and distributing various shop information with sound and animation, have appeared. These services require much more bandwidth to smoothly transmit multimedia data to users. Therefore, transmission rate becomes more important. A cellular system is an infrastructure used in a mobile communication between a cellular phone, called a node, and a base station. In a cellular system, a base station can smoothly communicate with nodes in the cell by avoiding overlap of frequency range with its adjacent cells. From the viewpoint of graph theory, however, that needs to divide the original frequency range into at least four sub-ranges. If a base station avoids overlapping its communication area, called a cell, with its adjacent base stations by appropriately controlling its transmission power, that is perfect cell partitioning, it can use the whole of the original frequency range. In this paper, we investigate the feasible area of the perfect cell partitioning. We first make modeling the perfect cell partitioning. Then, we provide geometrical analysis to clarify the feasible area of the perfect cell partitioning. Through several simulation experiments, we verify the accuracy of the analysis and show the effectiveness of our proposal. Simulation results show that the perfect cell partitioning is effective when the number of nodes in a cell is lower than 6 and the occupation ratio is 1.2.
