Abstract
The paradigm of cloud computing has emerged as a promising solution. It transparently provides computing, storage and communication resources, offered as an "elastic" pay-per-use service. This article analyses the evolution of Radio Access Networks (RANs), highlighting how current challenges and requirements for these networks as well as the available technology solutions drive the evolution of these networks towards the cloud. The Cloud-RAN architecture emerges as a solution that takes advantage of the characteristics of the cloud, adapting computation, radio and network resources in an elastic way, depending on the needs. This architecture is expected to reduce up to 15% of mobile operators’ acquisition costs and 50% of operating costs. The creation of an infrastructure is 3 times faster and will save up to 71% of energy compared to a traditional system.
