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, andfrequency 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.

In cellular networks, a new generation of CDMA or WCDMA-based networks will start operations in most countries in the near future. The standardized WCDMA technology generates new challenges in radio network planning, optimization and QoS management because of the dynamic nature of its radio interface and various new services and different network operating modes. Moreover, new and modified radio planning phases as well as new field measurements and emphasized QoS management are needed when UMTS networks are designed and optimized. Hence, a practical UMTS planning process must be defined in detail, from dimensioning to optimization tasks. This book follows the UMTS planning process. It is organized in three parts: Part I - UMTS configuration planning; Part II - UMTS topology planning; and Part III - UMTS network functionality. 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, theUMTS planning process is covered, and a detailed description of the UMTS power budget is given, with planning threshold examples provided.
