Описание: This text provides a technical history of the development of GSM (Global System for Mobile Communication) standards and the early evolution of UMTS (Univerisal Mobile Telecommunicaitons System). It presents background information and descriptions of the technical features of the GSM standards.
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.
