As smartphone users consume ever-increasing amounts of wireless data, operators are upgrading their networks to support LTE and LTE-Advanced. They are also deploying small-cell base stations to increase network capacity in congested areas and to extend coverage in sparsely covered areas.

Revenues are not necessarily increasing commensurately with bandwidth demand, however. The budget pressure on operators is in turn squeezing base-station OEMs. Fortunately, the onward march of Moore's Law and the trend toward smaller base stations are enabling semiconductor suppliers to integrate major baseband-processing functions in a single SoC.

In an effort to improve their return on investments, operators are looking at offloading cellular traffic to unlicensed spectrum. Chip vendors are taking different approaches to using this spectrum. At the same time, software-defined technologies and virtualization are changing traditional infrastructure equipment. The approach for base stations by each vendor differs in important ways. In some cases, vendors have made strategic decisions on the level of investment by the specific wireless infrastructure market segment. A Guide to Processors for Wireless Base Stations brings clarity to this evolving landscape by analyzing trends, describing the base-station processors, and drawing conclusions about the chip vendors and their products.

The report begins with an overview of 3G (UMTS) and 4G (LTE) technology, highlighting the aspects of the cellular network, the underlying communication technology, and relevant semiconductor technologies. We examine various options for using unlicensed spectrum to augment cellular communications. Another chapter discusses the major technology and business trends affecting the market for base-station processors, providing insight into the market's evolution. We examine new 5G technologies and make forecasts for residential, enterprise, and macro base stations. We also break down shipments of integrated base-station processors by vendor and project the potential revenue of this segment through 2020.

Following these introductory chapters, the report covers the major suppliers of base-station processors: Broadcom, Cavium, Intel, NXP (which acquired Freescale), Qualcomm, and Texas Instruments. We provide a synopsis of their business, explain their products' key features, and draw conclusions about their competitive standing and the types of designs for which their offerings are best suited. We also discuss the internal architecture of their processors, system-design considerations, and their likely product roadmaps.

We then dedicate a chapter to detailed head-to-head comparisons of some popular base-station processors. The report concludes with our outlook for the leading vendors.

As the leading analysts covering high-performance communications chips, The Linley Group has the expertise to deliver a comprehensive look at integrated base-station processors. Coauthors Jag Bolaria and Tom R. Halfhill use their broad experience in communications semiconductors and embedded processors to deliver the technical and strategic information you need to make informed business decisions.
