SAN JOSE, Calif., and BARCELONA, Spain -- Cavium, Inc. introduces a family of highly integrated single chip solutions that enable a new category of Macrocells and Smart Radio Heads supporting a wide range of deployment scenarios and setting a new bar for cost, performance, power and footprint. The OCTEON Fusion-M family is a scalable architecture that ranges from the single chip CNF75xx macrocell to the single chip CNF74xx for use in Smart Radio Heads.
Market Dynamics for Radio Networks and Cloud RAN
With the ever increasing demand for data and more concentrated and denser networks, operators are increasingly looking at ways to make the RAN more efficient and more scalable, as part of a wider trend towards virtualization of wireless networks through NFV and SDN technologies. Analysts predict that the overall wireless network infrastructure market encompassing macrocell RAN, HetNet, Small Cells and Cloud RAN will witness tremendous growth of 45% CAGR over the coming years, reaching $104 Billion in annual spending by the end of 2020.
Mobile networks' need to accommodate fast traffic growth, driven by heavier usage oFf individual subscribers and by the spread of wireless connectivity to new classes of IoT devices. The current architecture of the macrocell BTS utilizes a combination of CPUs, DSPs, FPGAs and ASICs which significantly add to the latency, footprint, power consumption and cost. The macro BTS can benefit from much higher silicon integration delivering higher performance while slashing the cost and power for next generation systems.
Current Radio Heads perform a limited function of capturing and transmitting the RF data to macro BTS or the Cloud RAN typically over dedicated dark fiber that is not readily available in all geographies. Radio Heads can benefit from integration of Layer 1 functionality to enable seamless virtualization of the upper layers in a Cloud RAN deployment utilizing the existing switched fabric in existence today. Future networks will continue to deploy macrocell BTS augmented with Cloud RAN for additional scalability and enterprise small cells for coverage and capacity.
New Category of Single Chip Macrocell and Smart Radio Heads: Laying the foundation of Dense HetNets, Cloud RAN and 5G standards
The OCTEON Fusion-M processors are single chip solutions for macro BTS and Smart Radio Heads that target next generation radio networks including 3GPP LTE Rel11/12. The key features include highly optimized full custom processor cores, a highly efficient caching subsystem, high memory bandwidth and a very flexible and high performance PHY. Cavium has a long history of delivering high-performance multi-core workload-optimized processors for networking, security and data plane processing applications through their highly successful OCTEON®, OCTEON Fusion®, NITROX® and Neuron Search® processor families.
