AUSTIN, TX -- (Marketwired) -- 07/14/14 -- Cellular infrastructure, such as the radio access network, traditionally has used industry-specific hardware owned and operated by mobile operators. Software-defined networking (SDN), network functions virtualization (NFV) and cloud radio access network (C-RAN) are among the initiatives starting to break that tradition. The result is that the RAN and evolved packet core (EPC) are slowly becoming applications that can run on off-the-shelf IT infrastructure hosted by data center operators and other third parties.
The first step in the evolution of the network is the process of moving from today's conventional remote radio head (RRH) deployments, where the baseband units (BBU) are deployed at the base of the cell tower, to an architecture in which the BBUs are deployed in one (or more) centralized data centers. The next step in this evolution is to an architecture in which the baseband units are deployed in data centers and the baseband functionality itself runs in virtualized software on generic computing platforms. This eventual architecture would divorce the 1:1 ratio between baseband and RRH, and thus give mobile operators the ability to support the same number of cell sites and sectors on less hardware. This would therefore be a true cloud RAN (C-RAN) deployment in a commercial data center.
"Once the evolution to C-RAN takes place, mobile operators are likely to realize both CapEx and OpEx savings," said Iain Gillott, president and founder of iGR, a market research consultancy focused on the wireless and mobile industry. "They will also realize other less easily quantifiable benefits, such as increased flexibility, faster and easier upgrade cycles and the ability to deploy new services and technology in fewer physical locations."
iGR's new market study, Cost Considerations for Centralized RAN and Cloud RAN, examines the process of moving from today's conventional remote radio head (RRH) deployment where the baseband units (BBU) are deployed at the base of the cell tower, to an architecture in which the BBUs are deployed in one (or more) centralized data centers. The market study examines the drivers, barriers and benefits of such a centralized architecture and also estimates the likely cost differences between a conventional RRH deployment, a centralized baseband deployment and a cloud RAN architecture.
The following key questions are answered in the new market study:
