Описание: This book will provide a technical system overview of 3G evolved networks which cannot be found in standard documents and other public material, opening the door to SAE/LTE (System Architecture Evolution / Long Term Evolution). The intention is not to rephrase the standard documents (as this may be seen in some publications) but rather to present the 3G evolution in a pragmatic way, providing links between the different pieces and trying to be as concrete as possible. A key element is the focus on inheritance and migration from 2G/3G systems towards "evolved 3G", rather than describing the new system as standing alone, so that the reader can understand the foundations and identify what the transition path for the end-user would be, as well as for the network operator. Other topics covered are: the physical radio layer, network architecture and the main services built on top of "evolved 3G.
Описание: With the deployment of LTE, most operators will have three simultaneous radio access technologies to manage, adding extra pressure to their already tight cost structures. This book offers a multi-technology approach that considers the implications of the different SON requirements for 2G and 3G networks, as well as 4G wireless technologies.
Описание: UMTS Radio Network Planning, Optimization and QOS Management describes practical planning process and gives solutions for detailed planning actions by following the planning process. The role of radio planning tool environment is emphasized by specifying the requirements of the digital map production, design tool, field measurement tool, and QOS measurement tool and by giving several examples of the results of these topics. By following the content of the book, a reader is able to build up an efficient UMTS planning and optimization tool environment and to carry out a practical UMTS planning and optimization project from configuration planning to field and QOS measurements.
Описание: Offers coverage from both a theoretical and practical perspective on the planning and optimization aspects of UMTS, and a number of other techniques to help operators get the most out of their networks. This book provides an end-to-end perspective, from network design to optimization.
Описание: The universalmobiletelecommunications system (UMTS) is a technical standard for a third generation (3G) telecommunication system. UMTS provides data rates more than three 1 times higher than its second generation (2G) predecessors. The increased speed en- ables, for example, video calls, music downloads, or fast web surfing. The technology is already widely available. In 2007, a total of 166 commercial UMTS radio networks are operational in 66 countries covering all continents (UMTS Forum, 207), and there are already more than 100 million UMTS subscribers (3GToday. com, 2007; UMTS Forum, 2006). The market for mobile telecommunication is, however, increasingly competi- tive, therefore operators need to invest effectively. In Western Europe, mobile phone penetration has reached 100 % in 2006 and the average revenue per customer is de- clining (3G. co. uk, 2007). Besides spectrum license fees, the main cost driver is network infrastructure (Ellingeret al., 2002). Radio network planning can cut operational and capital expenditure by up to 30 % (Dehghan, 2005). Good radio network planning is difficult for UMTS, because its radio interface is more complex than anything used at mass-market level before (Dehghan, 2005). Con- nections are separated via codes; they share the same frequency band and are thus subject to interference. On each link, the system constantly regulates the amount of generated interference to a minimum via a power-control feedback loop.
Описание: The first chapter in Part I introduces the UMTS and UTRAN systems and radio network planning strategy, and defines a planning process for UMTS. In Chapter 2, the UMTS planning process is covered, and a detailed description of the UMTS power budget is given, with planning threshold examples provided.
Описание: This book is a complete and practical guide to WCDMA/UMTS cellular network deployment. After introducing the network architecture of such a system, the
"WCDMA (UMTS) Deployment Handbook" defines the coverage and capacity concepts associated with the dimensioning and design phases. Progressing to a discussion of the main
system parameters associated with network optimization and detailing optimization techniques for the main services supported by UMTS, and includes the specifics of indoor deployment
and HSDPA networks evolution.
This book covers all stages from planning to optimization with sufficient details as required on a day-to-day basis, and thorough reference
information for the reader who wants to understand the concepts in more detail. It is relevant for daily tasks: the approach taken in this book is similar to the work flow of network planner
and optimization engineers, allowing such personnel to easily find the relevant information. It is written by the company which made CDMA a household name: Qualcomm was the first
company to use CDMA technology for cellular application and is a technical leader in this domain.
It is based on industry feedback: all the contributors to this book have
been working in direct interaction with WCDMA operators, throughout the world, since the early days of WCDMA commercial deployment. It looks to the future: this book addresses the
next level of challenge that WCDMA operators will face - deployment of indoor systems and HSDPA. Providing a complete introduction and reference guide to everything associated
with the life cycle of a WCDMA/UMTS cellular network, from initial dimensioning through to the successful deployment of indoor solutions, or migration to HSDPA, this book is a
must-have for network planners and optimization engineers as well as telecommunication engineering students.
Описание: This book will not only provide an accessible and comprehensible description of the first release and (beyond) of the new LTE standard, but importantly it will also provide the fundamental theoretical basis, which is essential to the development of a deep understanding of the concepts used in LTE. By developing the reader's understanding of the theoretical limits and how the theory has been applied to the practical standard, the book will provide the foundation necessary for engineers to focus their implementation efforts on the most critical aspects, and for researchers to identify the most fruitful areas for further development and future evolution. The book will provide a good balance between theory and practice. Particular effort will be devoted to explaining the theoretical concepts in an intuitive and comprehensive way, while retaining scientific rigour. Importantly, the goal of the book is not to make a collection of 3GPP contributions or to regurgitate specification documents, but rather to link their contents in a coherent and lucid explanation, highlighting the implications for practical systems and comparing / contrasting with the now well-known W-CDMA/HSPA standards. The book will focus primarily on the physical layer, but will also cover the higher protocol layers and the architecture to a sufficient degree for the reader to gain an overall understanding of the system. The book covers: Introduction and Background, Network Architecture, Protocols, Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Access (OFDMA), Detailed Downlink Physical Layer Design, Multiple antenna techniques, Broadcast Operation, Uplink theory and practicalities, Detailed Uplink Physical Layer Design, Uplink Procedures, Physical layer procedures, Handover and Mobility, Network Deployment, RF Impacts, Conclusions and Future Developments
Описание: LTE can access a very large global market- not only GSM/UMTS operators, but also some cdma operators and potentially fixed network service providers. The large potential market can attract large numbers of companies to the market place thus pushing the economies of scale that in turn enables wide scale LTE adoption with lower costs. This book will be one of the first books to market after the LTE L1 standard is finalised at the end of 2007. It will give a complete overview of LTE for UMTS and includes chapters on MBMS, HSPA Evolution and WiMAX. Chapter 1 gives an overview to LTE with chapter 2 covering the standardization background and process being. The system architecture evolution (SAE) is presented in Chapter 3 and the basics of air interface modulation choices in Chapter 4. Chapter 5 describes 3GPP LTE physical layer solutions and protocol solution is covered in Chapter 6. The mobility aspects are addressed in Chapter 7 and the packet scheduling in Chapter 8. Chapter 9 illustrates the radio and end-to-end performance while the voice performance is addressed in Chapter 10. Chapter 11 shows the operation of Multimedia Broadcast Multicast System (MBMS) and Chapters 12 and 13 describe other wireless broadband solutions: HSPA evolution in 3GPP Releases 7 and 8, and WiMAX based on IEEE and WiMAX forum definitions
