Dual Connectivity (DC) has been studied and proved to be an effective solution to deal with the fragmented resources in deployment scenarios where the macro and small cells use different frequency carriers. The performance of DC has mainly been analyzed using generic network models such as those proposed by the 3GPP. However, the benefits of DC in real networks have not been proved. In this paper, we investigate the performance of DC in a realistic deployment from a big European city. Additionally, a novel opportunistic cell selection technique is also proposed. Results show that DC does improve the performance in this realistic layout. Due to the uneven load distribution observed in realistic deployments, DC is able to provide fast load balancing gains also at relatively high load - and not only at low load as typically observed in 3GPP scenarios. For the same reason, the proposed cell selection technique that aims at performing intra-layer load balancing shows promising benefits in this irregular deployment.
