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: 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 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.

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.
