The role of homogenious networks in traditional cellular architecture has at most importance. This deployment reached almost limits in all urban areas but the traffic is increasing in rapid way. In these conditions, it is very difficult for the network operator to provide the experience of broadband to maximum users. To meet the requirements of traffic, it is recommended to deploy heterogenious network. The key design features are explained in this paper. The importance of range extension and time domain multiplexing partition are also explained.
