Demystifying Cloud RAN Architectures

Imagine a wireless service provider can provide service anywhere there’s Internet connectivity at the click of a button. All they need is a small remote radio connected to the Internet. The baseband modems no longer reside at cell sites, but are hosted in data centers where powerful commercial servers execute all the functions of todays base station baseband units. The remote radios can even be self-deployed by the mobile subscribers. The service provider would have full control of the service features which can be configurable on the fly. Sounds like science fiction to some, but this is what virtualization of the radio access network aims to achieve.

No wonder then that the term Cloud RAN which meant centralization and virtualization of baseband became an overused term to denote all types of architectures. We live in the world of Anything as a Service (XaaS). Which investors would put money now in a hardware company? Read more of this post

Cloud RAN Promises to Shape Future Wireless Networks

Wireless Cloud RANWe have released our annual Cloud RAN report with new insights and analysis on the development of this market during 2014. Cloud RAN is certainly gaining in interest in the operator community. This is due to practical reasons related to cost savings that can be realized first by the process of centralization and then by the virtualization of the radio access network. In our analysis of this market, we took a quantitative approach by analyzing the business case for different deployment scenarios (macro cell, HetNets) in different markets (Asia, North America), to determine a plausible evolution and market potential for Cloud RAN. The findings were extremely interesting as they exposed where Cloud RAN makes sense and under what conditions and use case scenarios. This is critical as Cloud RAN has impact on a number of other mobile network solutions such as small cells and distributed antenna systems (DAS). Read more of this post
