Deployment Guidelines for Cloud-RAN in Future Mobile Networks

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


This work identifies and addresses current challenges and shortcomings arising in deployment and expansions of today’s mobile networks, in order to determine the future of the Cloud-Radio Access Network (C-RAN) architecture. C-RAN proposes a three-fold RAN architecture, improving the flexibility, energy efficiency and performance of the RAN. On the other hand, C-RAN requires a division of the base station functionalities resulting in very high requirements to the interconnecting transport network, the xhaul. C-RAN has been promoted as the network architecture for 5G and future mobile networks; however, it has not yet been adopted by the majority of network operators. This work studies existing deployment scenarios and evaluates deployment opportunities for green- and brownfield installations in rural, urban, high mobility and latency sensitive areas. The studies are backed up by examinations of real-life network traffic, predicting that in a group of cells covering multiple different areas, C-RAN will improve network resource utilisation by a factor > 2. The outcome of this work results in a set of concrete deployment guidelines for the introduction of C-RAN in brownfield network installations and future greenfield installations. The deployment guidelines include functional divisions of the RAN, functional placement scenarios and xhaul network requirements.
