Centralized RAN or C-RAN is an architectural shift in RAN (Radio Access Network) design, where the bulk of baseband processing is centralized and aggregated for a large number of distributed radio nodes. In comparison to standalone clusters of base stations, C-RAN provides significant performance and economic benefits such as baseband pooling, enhanced coordination between cells, virtualization, network extensibility, smaller deployment footprint and reduced power consumption.
Initially popularized by Japanese and South Korean mobile operators, C-RAN technology is beginning to gain momentum worldwide with major tier 1 operators – including Verizon Communications, AT&T, Sprint, China Mobile, Vodafone, TIM (Telecom Italia Mobile), Orange and Telefónica – seeking to leverage the benefits of centralized baseband processing.
SNS Research estimates that global investments in C-RAN architecture networks will reach nearly $9 Billion by the end of 2017. The market is further expected to grow at a CAGR of approximately 24% between 2017 and 2020. These investments will include spending on RRHs (Remote Radio Heads), BBUs (Baseband Units) and fronthaul transport network equipment.

The report has the following key findings:
– Expected to reach nearly $9 Billion in global spending by the end of 2017, C-RAN is increasingly becoming the preferred approach to deploy future mobile networks. The market is further expected to grow at a CAGR of approximately 24% between 2017 and 2020.
– Small cells are also beginning to be deployed in a C-RAN architecture to leverage the benefits of resource pooling and multi-cell coordination. This trend is particularly prevalent in the indoor and enterprise segments, with a number of dedicated vendor solutions such as CommScope’s OneCell, SpiderCloud’s E-RAN, Ericsson’s Radio Dot, and Huawei’s LampSite.
– Mobile operators are exploring multiple baseband functional split options for C-RAN implementation, as they seek to ease the transition to 5G networks while reducing fronthaul costs.
– By the end of 2020, SNS Research estimates that vRAN/Cloud RAN deployments with virtualized baseband processing will account for nearly 20% of all C-RAN investments.
– The vendor arena is continuing to consolidate with several prominent M&A deals such as Mavenir Systems’ recent merger with C-RAN specialist Ranzure Networks, which has positioned the company as an end-to-end provider of 5G-ready mobile network solutions.
