Jul 24, 2015, 10:15 ET from Research and Markets

DUBLIN, July 17, 2015 /PRNewswire/ -- Research and Markets (http://www.researchandmarkets.com/research/jt3n66/analysis_of) has announced the addition of EJL Wireless Research's new report "Analysis of Centralized Radio Access Network (C-RAN) Technology " to their offering.

This report provides a comprehensive technology analysis on centralized radio access network (C-RAN) architecture for mobile networks. A detailed analysis covering the implementations and evolution of the radio access network is included along with case studies from mobile operators.

The objectives of the report are to analyze the feasibility and commercial deployment of a C-RAN concept and associated technologies through the evaluation of its technical and business viability. This study traces back to the time that distributed base station and base station pool concepts were invented, which explores where the concept of C-RAN originally cam from and how it has been gradually evolved from distributed base station to base station hotel to baseband hotel and eventually transformed to the concept of C-RAN, which includes Centralized RAN, Cloud RAN, and Virtual RAN over the past 15 years.

Our analysis focuses on the technical feasibility and economical viability of newly invented concepts through the review of research activities in the industry. Additionally, we analyze some pioneering C-RAN deployments in Asia, comparing short term and long term economical gain with the impact of long term technology evolutions.

This report offers a complete and objective view about C-RAN and how it will fit into the future evolution of broadband mobile networks, supporting fixed and mobile network convergence and consolidation.


- C-RAN is actually a concept evolved from the distributed base station and baseband hotel architecture - Newly added features of C-RAN include centralized BBU with traffic switching, baseband processing server (Data Unit), Cloud RAN and Virtual RAN - The challenges with statistical multiplexing of the fronthaul network for C-RAN are clock and frame synchronization in addition to significant bandwidth throughput requirements - DAS can be considered as a special case of the base station hotel concept with one or a group of base stations with fiber connected radio units; active DAS could be considered as a special case of C-RAN - The performance gain of CoMP may not justify the added network complexity and the cost to deploy a dark fiber connection to RRH in the near term - C-RAN can significantly save both CAPEX and OPEX costs with current RAN configurations and base station technology if the investment for the fiber connection is not considered. The OPEX gain of C-RAN will shrink as BTS technology continues to evolve.
