| Abstract | The concept of overlaid cells being relatively new needs some investigation into it, regarding, how by using the overlaid cells, in best way hot traffic zones can be accommodated. The investigation of optimal position of microcells and their power is an important area in design of such network. In this thesis study, it is intended to deploy a number of micro base stations, in an existing macrocell system, to accommodate excess increase in traffic. Suitable propagation models are selected each for characterizing propagation in macrocells and microcells. Various interferences present in such systems are analyzed and their subsequent effect on microcell size, number and power requirement are studied. A direct search algorithm is applied to determine optimal positions of micro base stations and their power. A number of cases with varied traffic demand are studied. It is seen that overlaid microcell can be deployed with frequency reuse from macrocell but some power increment is necessary to overcome interference from macrocells. From the placing of transmitters in optimal positions, it is seen that, higher amount of traffic can be supported, with maximum utilization of channel capacity. |
