Описание: The book provides a comprehensive investigation of the performance and problems of the TCP/IP protocol stack, when data is transmitted over GSM, GPRS and UMTS. It gives an introduction to the protocols used for Internet access today, and also the Wireless Application Protocol (WAP). The basics of GSM, GPRS and UMTS are given, which are necessary for understanding the main topic, TCP performance over GSM, GPRS and UMTS. We describe at length the problems that TCP has when operating over a mobile radio link, and what has been proposed to remedy these problems. We derive the optimum TCP packet length for maximum data throughput on wireless networks, analytically and by simulation. Results on the throughput and various other parameters of TCP over mobile networks are given. This book gives valuable advice to network operators and application programmers to maximize data throughput, and which protocols, transmission modes, and coding schemes to use and which to avoid.

Описание: Radio network system planning is a comprehensive optimisation task where different planning targets - coverage, capacity and quality- have a direct influence on each other and where optimised solution is a compromise of these planning areas. In order to find out the cost effective and high quality radio network plan the well-known theoretical details have to be bound with practical radio planning issues like planning phases and planning parameters. At the same time the long-term network evolution paths and the possible changes of the radio propagation environment have to be well understood. Radio Interface System Planning for GSM/GPRS/UMTS introduces the radio system planning where these theoretical and practical details have both been emphasized and then utilized for the planning of GSM, GPRS and UMTS mobile networks. The key planning parameters for these systems are explained and the typical values for power budget, various margins, gains and losses, and frequency reuse are given. Also, the book describes the common tasks in radio system planning. The planning methods and phases introduced in the book can also be applied to other mobile communication systems.
Описание: Providing an accessible introduction to all stages of planning and optimizing UMTS, HSPA, and LTE cellular networks, this book supplies a comprehensive explanation of the fundamental aspects of current and future cellular networks. It starts with an overview of each type of network, including basic techniques and channel models. Next, it examines the challenges operators and vendors are likely to face and explains the critical role network planning and optimization play in addressing these challenges. The book details effective system level simulation methods and describes key techniques in planning, troubleshooting, and optimizing these networks.
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: 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
Описание: Practical Implementation of HSPA in UMTS Networks: Performance and Evolution will convey the practical implementation aspects of HSPA in UMTS networks to practicing engineers in the wireless industry. It will incorporate real-world performance data and network optimization insights from a mobile operators perspective and will provide a state-of-the-art insight of the performance of HSDPA and HSUPA technology, including extensive documentation from real network trials with emphasis on actual lab and field performance. The book will cover the basics of the technology before moving on to the critical topics of network optimization and performance tradeoffs observed in the real world. The expectations that operators have when selecting this technology are explored and the major practical challenges that are faced during deployment and operation of an HSPA data network will be addressed. It will provide a reference for engineers to optimize the networks, highlighting the areas that in practice present a higher impact on the network performance.
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: 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.
