To stay ahead of continually increasing mobile bandwidth demand while managing cost and efficiency, service providers are expanding and transitioning from a typical distributed radio access network (RAN) architecture to a C-RAN network topology. In C-RAN, base band units (BBUs) are co-located at a remote facility, and connected via fiber links – based on the Common Public Radio Interface (CPRI) or Open Base Station Architecture Initiative (OBSAI) standards – to a substantial number of remote radio heads (RRHs) spread around the network. Where C-RAN offers network and operational efficiencies, it also creates an opportunity for mobile service providers to improve quality of …
