In such an architecture, the design and optimization of the backhaul plays a crucial role. In this paper we review different available backhaul technologies and discuss their characteristics for use in cloud-based networks. We point out, how a heterogeneous backhaul network and a flexible centralization enables the proposed architecture and give an outlook on how a joint design of access and backhaul can help in meeting the increased demands. }, booktitle={First International Workshop on Cloud Technologies and Energy Efficiency in Mobile Communication Networks (CLEEN 2013), 2013 IEEE 78th Vehicular Technology Conference (VTC Fall)} }
