Small cell network topology comparison

Abstract

One of the essential problems in a mobile network with small cells is that there is only a limited number of (PCIs) available. Due to this fact, operators face the inevitable need for reusing (PCIs). In our contribution, we are dealing with a (PCI) assignment to FAPs in three different topologies. The first model places FAPs randomly within the network while respecting overlapping defined. The second model places FAPs in a grid without other restrictions. The third model forms a grid as well, although buildings and roads are taken into account and (FAPs) are always inside buildings. The proposed models are compared and a conclusion is made based on simulation results.
