Languages : en
Pages : 423
Book Description
This book describes the physical mechanisms involved in the propagation of electromagnetic waves in the radiofrequency range, inside and outside buildings, in the terrestrial and near space environments, with a special focus on mobile radio communication. It combines a theoretical and an experimental approaches with an understanding of the physical environment through adequate formulations of the laws of electromagnetism. It should thus provide the background needed by advanced students and development engineers for the conception of high quality and reliable telecommunication systems.

Signaling System No. 7 (SS7/C7)
Author: Lee Dryburgh
Publisher: Cisco Press
ISBN: 9781587050404
Category : Computers
Languages : en
Pages : 756
Book Description
A complete, practical guide to the world's most popular signaling system, including SIGTRAN, GSM-MAP, and Intelligent Networks. Provides in-depth coverage of the SS7 protocols, including implementation details Covers SS7 over IP (SIGTRAN) using real-world examples Covers SS7/C7 from both a North American and European perspective, providing a broad international understanding of the technology and associated standards Explains mobile wireless concepts and signaling, including mobile application part (MAP) Provides a thorough explanation of the Intelligent Network (IN) and associated protocols (INAP/AIN) Signaling System No. 7 (SS7) is a signaling network and protocol that is used globally to bring telecommunications networks, both fixed-line and cellular, to life. SS7 has numerous applications and is at the very heart of telecommunications. Setting up phone calls, providing cellular roaming and messaging, and supplying converged voice and data services are only a few of the ways that SS7 is used in the communications network. SS7 also provides the point of interconnection between converging voice and data networks. This transition, which affects everyone who works with the data network, has bolstered the need for practical and applied information on SS7. In short, anyone who is interested in telecommunications should have a solid understanding of SS7. Signaling System No. 7 (SS7/C7): Protocol, Architecture, and Services will help you understand SS7 from several perspectives. It examines the framework and architecture of SS7, as well as how it is used to provide today's telecommunications services. It also examines each level of the SS7 protocol-all the way down to the bit level of messages. In addition, the SIGTRAN standards are discussed in detail, showing the migration from SS7 to IP and explaining how SS7 information is transported over IP.

Starting Digital Signal Processing in Telecommunication Engineering
Author: Tomasz P. Zieliński
Publisher: Springer Nature
ISBN: 3030492567
Category : Technology & Engineering
Languages : en
Pages : 874
Book Description
This hands-on, laboratory driven textbook helps readers understand principles of digital signal processing (DSP) and basics of software-based digital communication, particularly software-defined networks (SDN) and software-defined radio (SDR). In the book only the most important concepts are presented. Each book chapter is an introduction to computer laboratory and is accompanied by complete laboratory exercises and ready-to-go Matlab programs with figures and comments (available at the book webpage and running also in GNU Octave 5.2 with free software packages), showing all or most details of relevant algorithms. Students are tasked to understand programs, modify them, and apply presented concepts to recorded real RF signal or simulated received signals, with modelled transmission condition and hardware imperfections. Teaching is done by showing examples and their modifications to different real-world telecommunication-like applications. The book consists of three parts: introduction to DSP (spectral analysis and digital filtering), introduction to DSP advanced topics (multi-rate, adaptive, model-based and multimedia - speech, audio, video - signal analysis and processing) and introduction to software-defined modern telecommunication systems (SDR technology, analog and digital modulations, single- and multi-carrier systems, channel estimation and correction as well as synchronization issues). Many real signals are processed in the book, in the first part – mainly speech and audio, while in the second part – mainly RF recordings taken from RTL-SDR USB stick and ADALM-PLUTO module, for example captured IQ data of VOR avionics signal, classical FM radio with RDS, digital DAB/DAB+ radio and 4G-LTE digital telephony. Additionally, modelling and simulation of some transmission scenarios are tested in software in the book, in particular TETRA, ADSL and 5G signals. Provides an introduction to digital signal processing and software-based digital communication; Presents a transition from digital signal processing to software-defined telecommunication; Features a suite of pedagogical materials including a laboratory test-bed and computer exercises/experiments.

Understanding Changing Telecommunications
Author: Anders Olsson
Publisher: John Wiley & Sons
ISBN: 047086852X
Category : Technology & Engineering
Languages : en
Pages : 542
Book Description
The field of telecommunications is becoming ever more complex. In order to manage the new Telecom industry it is necessary not only to understand its 3 main components, namely the end users, the technology and networks, and the business aspects, but also their vital inter-relationships. Complexity leads to uncertainty, and one effect of uncertainty is for people to underestimate the complexity of the business and the technology. This book takes a holistic approach to the subject and can be used as a tool for decreasing this uncertainty. During 2000 many operators paid extremely high sums of money for 3G licenses in a number of European countries, supposing a potential corresponding and balancing revenue from mobile services in the new frequency band. Obviously today the licenses are questionable. Consequently, suppliers and operators were forced to reduce their international work force. What are the underlying reasons? Since the true rate and level of development was hardly foreseen by anyone, the picture is complex, including factors such as psychology and belief in a new economy. It is immediately clear that the end user impact has been severely under-estimated. It is also clear that the expected development has and is happening, with more speed than expected, and continues to be complemented with solutions such as wireless LANs. This book treats the paradigm shift from a number of angles: user needs and demands, deregulation of telecom and the convergence between telecommunications, data communications and the media industry, the service plan, service implementation, QoS, and Security. Understanding Changing Telecommunications focuses on the overall principles and context of the new telecommunications world rather than on high-level technical descriptions in order to aid the understanding and development of the next generation of telecom networks. e.g. multimedia over IP and 3G. Discusses the development of telecommunications up until 2005 Provides a holistic view of the world of telecommunications Covers three main areas: End-users, Technologies and Networks, and Telecom Business, and their vital inter-relationships Offers support and advice for those needing to implement business plans Essential reading for staff with operators and providers involved in the telecom networks, especially management, planning and design, development, integration and training, as well as Business analysts and investors keen to understand the current state of the Telecom industry.
