Future Trends in the Cell Site Planning For Capacity Enhancement

In this paper, my aim is to provide an overview of the key challenges arising from Het Nets, Relay Nodes, SON, RRM, Co-MIMO, Cognitive Radio Network, DAS and highlight their importance. Recent research mainly concentrates on the aspect of interference mitigation, radio resource utilization, fairness, complexity and QoS. Improve the coverage as well as the capacity with high speed achieved by HETNET. Increase reliability and performance of the network achieved by RRM. Reduce the amount of manual process with the help of SON. Power allocation (PA) plays an important role in capacity improvement for cooperative multiple-input multipleoutput (Co-MIMO) systems. Cognitive radio technology improves radio resource usage and minimize cost-flow problem. The reduction in energy consumption is achieved by considering fast power control.
