Rosenberg A. CDMA Capacity and Quality Optimization

2003. - 629 p. ISBN: 0071399194To grow wireless systems today, we need a deep understanding of wireless technology. This draws on the disciplines of physics, mathematics, radio, telephony, data technology, television, economics, quality management, and business management. To move this technology into the future, we need to understand its roots in the past. Each of our readers undoubtedly has a great deal of expertise in some of these disciplines, some in others, and little or none in the remaining ones. We want all our readers to be expert in some of these areas and conversant in all of them. As a result, we have structured the text to provide each reader with all that is needed to gain basic knowledge where it is needed and develop advanced knowledge at the cutting edge of wireless technology, the third-generation (3G) systems that are being deployed today.The first four parts of the text provide the core knowledge necessary to understand wireless technology, including "Key Radio Concepts," "Standards for Cellular Systems," "Key Telephony Concepts," and "Key Data Concepts." We recommend to each reader that you evaluate your depth of understanding in each of these areas. If you are expert in an area, feel free to skim or skip that part of the text. If you came to wireless through another area and are less familiar with a particular part, we recommend that you read it thoroughly. It should be both engaging and informative.For example, one of the authors (Kemp) came to wireless technology from the field of data systems management. In developing the parts of the text on radio and telephony, I learned a great deal and also found that people in these fields face fundamentally different problems and find different approaches than do those in data systems. Developing an understanding of all the approaches to engineering problems in the root technologies that make up wireless systems is a key to becoming a genuine expert and leader in the field. If, in reading later parts of the book, you find some concepts or terms unclear, we suggest that you return to the relevant "Key Concepts" part to clarify the issue.Part 5, "Capacity and Quality Principles," introduces fundamental concepts such as tradeoff and optimization in precise language. We are always seeking to develop the best system for a particular purpose using limited resources while facing underlying physical constraints. The theory we need to define these problems and develop solutions is laid out in Part 5.Part 6, "Planning for CDMA Capacity," applies the principles in Part 5 to the situation where engineers are deploying entirely new systems or performing upgrades of existing systems with a large budget for new technology. It is designed primarily for planners and engineers on these large-scale projects and is also valuable for less technical administrators who need to understand the technology for their work.Part 7, "Increasing Capacity," applies the principles from Part 5 to the situation of maintaining and improving existing CDMA networks. This part is written for engineers and technicians who maintain and grow systems at times when the budget is smaller and the changes being made are not as extensive as they would be in the rollout of a complete network upgrade or new network.Part 8, "Modeling for CDMA," introduces the various modeling theories and methods that help us predict CDMA capacity and quality of service. It also explores methods of using models as simulation tools for troubleshooting network problems. It will be of value to planners, engineers, and technicians developing and improving CDMA networks.Part 9, "CDMA Now and in the Future," gives a picture of how wireless technology is operating across the globe and changing our society. It presents the challenges and opportunities we face in improving communication for a mobile, global society.
