d or overcome them. We also delve into roadmap management, with suggestions on how to keep them relevant using reliability engineering, organizational culture, and evolution concepts. How This Book Is Structured Chapter 1, "Network Planning," covers the nuts and bolts of deployment, and gives a speedy tour of the whole process. Chapter 2, "Self-Organizing Networks and LTE Deployment," gives a general overview of SON concepts, and helps explain how SON attempts to solve various deployment issues. Chapter 3, "Deployment Challenges in Evolving 4G," introduces readers to the challenges of LTE deployment, and highlights trends in user and traffic profiles, as well as newer trends like the Internet of Things, which need to be accounted for by LTE networks. Chapter 4, "Network Roadmaps," introduces roadmap concepts for networks and provides further coverage of factors that can affect stakeholders. Chapter 5, "Network Roadmap Evolution," focuses on how network roadmaps have to evolve and adapt to changes in technology, markets, deployments, and traffic patterns. Chapter 6, "A Process for Network Roadmaps Evolution," presents a detailed set of processes for network roadmap management and evolution. Prerequisites For the deployment-related sections of the book, readers are expected to have knowledge of LTE and radio basics, and have some practical idea of what is to be accomplished. For sections covering network roadmap management and evolution, readers should have a basic understanding of network product development. CHAPTER 1 Network Planning Network planning, especially for a cellular network, can be an extremely complex as well as time-consuming procedure. There are many steps and parameters that should be considered to ensure a well-planned radio network. This chapter gives a fast tour through the network planning and optimization of a Long Term Evolution (LTE) radio network. We also present a strong grounding through the various aspects of the LTE standard and features that you can use as a guide through the various
