  "abstract": "<p>Due to the increasing penetration of smart devices and data intensive applications, mobile network operators are experiencing exponential data growth. In effect, network capacity limitation that leads to performance degradation is observed. To address this limitation, deployment of different types of small cells under umbrella macro network that results Heterogeneous Networks (HetNets) has been considered as one key capacity enhancement approach. In the introduction of HetNets, operator decision on spectrum allocation scheme significantly determines network performance.<br>\nThe Ethiopian sole telecom operator, ethio telecom, has recently started the path to operate and manage HetNets by deploying small cells within its existing macro network. Nevertheless, there is no thorough performance study on potential spectrum scenarios considering Ethiopia&rsquo;s network environment so that an informed spectrum usage strategy is formulated. Spectrum scenarios can be cochannel, where small cells apply same frequency band used by macro cells, dedicated, where they apply different frequency bands or a hybrid of cochannel and dedicated.</p>",
