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: 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: 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: "Radio Network Planning and Optimition for UMTS, Second Edition", is a comprehensive and fully updated introduction to WCDMA radio access technology used in UMTS, featuring new content on key developments. Written by leading experts in the field, the first edition quickly established itself as a best-selling and highly respected book on how to dimension, plan, and optimise UMTS networks. This valuable text examines current and future radio network management issues and their impact on network performance, as well as the relevant capacity and coverage enhancement methods. In addition to coverage of WCDMA radio access technology used in UMTS, and the planning and optimisation of such a system, the service control and management concept in WCDMA and GPRS networks are also introduced. This is an excellent source of information for those considering future cellular networks where Quality of Service (QoS) is of paramount importance. The key features of the second edition include: High-Speed Downlink Packet Access (HSDPA) - physical layer, dimensioning and radio resource management; Quality of Service (QoS) mechanisms in network for service differentiation; Multiple Input - Multiple Output (MIMO) technology; practical network optimisation examples; service optimisation for UMTS and GPRS/EDGE capacity optimisation; and the 'hot topic' of service control and management in WCDMA and GPRS networks, that has evolved since the first edition. The companion website includes: figures; and static radio network simulator implemented in MATLAB[registered]. This text will have instant appeal to wireless operators and network and terminal manufacturers. It will also be essential reading for undergraduate and postgraduate students, frequency regulation bodies, and all those interested in radio network planning and optimisation, particularly RF network systems engineering professionals.
Описание: The original book was the first text to jointly assess the topics of both physical-layer and network-layer aspects of wireless systems using a cross-layer optimisation approach and it stimulated much of the research that led to the standardisation of the HSDPA 3G system. In the five years since the first edition was published the wireless landscape has evolved further. The new book addresses the recent developments in the field of HSDPA-style wireless networking, focusing particularly on the issues and challenges of FDD versus TDD networking. The book provides an all-encompassing, self-contained overview of the subject for a wide range of readers. The material is presented clearly and logically allowing the uninitiated reader to commence reading it at fundamental non-mathematical conceptual level at the beginning of the book, while advanced readers can turn directly to the required chapter describing solutions to a number of wireless FDD or TDD networking problems.

Описание: Based on the Global System for Mobile (GSM) standard, UMTS, endorsed by major standards bodies and manufacturers, is the planned standard for mobile users around the world and is at present still being made available. Once UMTS is fully available geographically, computer and phone users can be constantly attached to the Internet as they roam, and have the same set of capabilities no matter where they travel. As researchers, developers and operators prepare for these advances, they need to have access to a resource providing cutting-edge advice on QoS and QoE management issues applied specifically to UMTS networks. This book sets out to provide state-of-the art advice on Quality of Service (QoS) and Quality of Experience (QoE) in Universal Mobile Telecommunications (UMTS) networks. The approach is comprehensive, tackling mobile service planning, provisioning, performance monitoring and optimization issues in a single, accessible resource. It includes strong sections on WCDMA QoS and QoE management functions in packet core and backbone networks. It provides a strong focus on QoS and QoE issues related to present and forthcoming application services, including multimedia messaging service (MMS), school-wide information system (SWIS), gaming, streaming and browsing. It illustrates all points with examples gleaned from state-of-the art research from around the globe. It is suitable for operators, vendors, deployers, consultants and managers specializing in the research and development of products and tools for QoS and QoE management in UMTS networks. It will also appeal to postgraduate students and researchers in the field of telecommunications and specializing in UMTS QoS and QoE principles and practice.
