The C-RAN deployment requires high-bandwidth fiber for the C1 interface between the BPF and the RF (CPRI fronthaul). Like the distributed macro architecture of 7b, the C-RAN deployment offers a GPP environment for VNFs and applications in the central office. The GPP may be part of a distributed data center, in which case, the PPF and RCF are deployed as VNFs, while the SPP is deployed as... In this context, centralized RAN (C-RAN) comes with an innovative solution for the changes that will occur in the network. C-RAN shifts all the complex functionalities from the base stations (BS) to the central office (CO). A new segment called fronthaul connects the base band unit (BBU) with the remote antenna over a digital radio over fiber (DRoF) transmission based on the common public
CLOUD RADIO ACCESS NETWORK TECHNOLOGY FOR THE NEXT
C-RAN is also “open” in the sense that C-RAN is designed to provide a set of standard application programming interfaces (APIs) to outside parties to encourage new service development on the edge and to provide interoperability.... access networks (both abbreviated to C-RAN). In these networks, the BBU moves from the cell site to a central BBU hotel location. This creates a new fronthaul network between the BBU and the cell site based on the Common Public Radio Interface (CPRI) or Open Base Station Architecture Initiative (OBSAI) protocols, which are effectively digitized radio frequency (RF) signals. These networks

In addition, cloud radio a ccess network (C-RAN) architectures are considered instrumental to fully exploit the capabilities of f uture 5G RANs. However, RAN centr alization imposes stringent requirements on the transport network, which today are address ed with purpose-specific and expensive fronthaul links. As the demands on future access networks rise, so will the challenges in the dice games math grade 1 pdf Challenges for future 5G networks Agility, openness, scalability, efficiency • So many issues for current “hard” mobile networks

- OBSAI, quite similar to CPRI, was established in late 2002 before CPRI. It has been adopted by many base station vendors like Samsung, NSN, etc. Aimed to build an open base station structure, OBSAI divides key features of a base station into modules, and interconnects the modules using an interface named RP (Reference Point).
