Rapid and consistent mobile broadband consolidation, doubling year over year, will bring a tsunami of data traffic, representing in 2020 1000x of the traffic in 2010. Mobile Data Traffic Dozens of billions of connected devices foreseen by industry (GSMA, Ovum, MachinaResearch etc.) on upcoming decade. Internet of Things All customer requirements are not equal. It is worthwhile to discover which attributes of a product or service are more important to the customer. Negative perception of services is the major reasons for changing of service provider Customer Experience Main broadband dilemma: Traffic and Revenue decoupling. It brings a continuous research for cost effective and affordable solutions. Flat Revenue 1000x

  8. 8. Why Centralizing? CAPACITY & COVERAGE: Centralized RAN acts as huge Base Station and can easily coordinate resources for interference avoiding by using functionalities such as CoMP and e-ICIC. CoMP and e-ICIC can together increase the system capacity in 30 times distributed network; C-RAN is also suitable for non-uniformly distributed traffic due to the load-balancing capability in the BBU pool. Though the serving RRH changes dynamically according to the movement of UEs, the serving BBU is still in the same BBU pool. 50% of voice traffic and 80% of data traffic are performed in indoor environment, and due concentrated traffic , indoor traffic density can represent 10-100 times outdoor environment; Centralized RAN can be optimal solution and accordingly to Airvana and it is 69% cheaper than DAS; TRANSMISSION & INFRASTRUCTURE: Algorithms such as e-ICIC and CoMP have tighter latency requirement below 10 micro seconds. In general IP backhaul transport cannot accomplish this latency level in X2 interface. Network Synchronization can be simplified by requiring synchronism in less centralized sites Currently almost LTE Cell Site is attended by fiber and DWDM is affordable solution for transport CPRI inside of lambdas. Space/Colocation, air conditioning and other site support equipment's power consumption can be largely reduced. China Mobile estimates a reduction of 71% of power saving comparing to Distributed Cell Site; ROLLOUT, OPERATION & MAINTENANCE : Faster system rollout due simpler remote cell site that reduces 1/3 comparing to Distributed RAN. Multi-Tenant BBUs are aggregated in a few big rooms, it is much easier for centralized management and operation, saving a lot of the O&M cost associated with the large number of BS sites in a traditional RAN network. TCO : Accordingly to China Mobile, 15% and 50% of CapEx and OpEx savings respectivelly comparing to Distributed RAN Core Net. BBU TDM IP BBU BBU Core Net.
