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 topic of this book is Coverage Solutions for Cellular Networks in buildings. It provides an overview and background of Cellular systems technology. It covers why Indoor Coverage is needed for GSM, CDMA and UMTS networks and how this coverage is achieved, from basic passive systems all the way through to advanced fiber optic systems. Each method is discussed in detail giving the reader a good understanding of all the available solutions. There is a section to cover multi operator systems, as this is becoming a more and more utilized approach. Techniques like Repeaters, BDA, Passive Antennas Systems, Fiber Optic Systems are explained in detail and there is a dedicated section on how to design an In-building solution for any technology, GSM, UMTS, PMR and TETRA. It gives details on everything required to design a working in-building solution, as well as how to install it. Other sections cover noise, link budgets and software tools that can be used to provide help with in-building designs.

Описание: A comprehensive discussion of multiple access protocols for cellular systems and the consideration of the specific constraints and capabilities of second and third generation systems regarding the multiple access protocols. Beginning by introducing the cellular concept and discussing second and third generation cellular communication systems, including the evolution from these systems to IP-based systems, the authors then identify the requirements for and problems related to multiple access. In accordance with ETSI and 3GPP standards, a split is made into basic multiple access schemes such as CDMA, TDMA and FDMA and multiple access protocols. The pros and cons of CDMA and TDMA for third generation systems are discussed as well as medium access in GSM, GPRS and UMTS, essentially based on R-ALOHA protocols in all these systems. Data access delay and voice dropping performance is assessed and the different UTRA modes are considered. - Provides an accessible text for individuals with little prior knowledge of cellular communication systems or multiple access protocols - Provides an overview of existing material on cellular communications, multiple access protocols and a combination of the two - Presents extensive research carried out by the authors including extended packet reservation multiple access protocols for TDMA, CDMA and hybrid CDMA/TDMA air interfaces, protocol enhancements and modelling of the physical layer A valuable reference resource for researchers and engineers in the field of cellular communications and packet-based communications, as well as postgraduate and research students in this rapidly evolving field.
Описание: Radio Access Networks for UMTS provides readers with a description of the UMTS radio access network, describing the key subjects in detail and covering all fundamental subjects. Starting with the high-level network architecture, the book describes the flow of data through the network. Content can be divided into three distinct sections: Section 1 provides readers with a detailed understanding of the UMTS radio access network from the perspective of application data and control plane signalling. Explanations are based upon Release 6 of the 3GPPs specifications and some references are made to Release 7 where appropriate. This section includes a description of the protocol stack and radio resource functionality. It also includes information on HSDPA, HSUPA and the Iub transport network, all of which are gaining greater importance in todays network deployments. Section 2 focuses on complete signalling procedures. This will include descriptions of complete message sequences - to demonstrate some of the most common procedures encountered in the field as well as a step-by-step analysis of message content. The most significant phases of each procedure (in terms of network performance) are also identified. Section 3 addresses the more practical issues of system dimensioning and system planning. Link budgets and capacity calculations are described in detail. The most important radio network planning principles are also described in detail in terms of methodology, scrambling code planning, neighbour planning, antenna subsystems, co-sitting, microcells, indoor solutions, repeaters and operating bands.
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.
