This book presents the technical characteristics of the two radio network interfaces of mobile 4G, LTE and LTE Advanced, based on Release 8, 9 and 10 of the 3GPP specifications. Points covered include a detailed description of various components of the radio interface. RRC signaling messages used to establish the connection, enabling the security, the paging, the establishment and the release of dedicated and default support and the handover. The PDCP ensures the security of the transmission and allows the recovery during handover and the compression of the headers. The RLC protocol defines the transmission modes with or without acknowledgment. The MAC protocol determines the random access, the data transfer, the timing advance, the scheduling and the discontinuous reception. The physical layer includes a description of the methods of multiplexing (time, frequency and space) and the various signals and physical channels.

Professionals quickly discover that, although the technical specifications for GPRS cover all parts of the engineering functions in detail and depth, they are lacking in one important feature; the conceptual framework within which the specifications sit - "GPRS in Practice" fills this gap. By beginning with an explanation of why GPRS is necessary and describing the core concept of GPRS operations, the TBF (Temporary Block Flow), a revision section then covers the GSM Air Interface with its Radio, Physical and Logical channels and this progressively leads to the GPRS logical channels - what they do and how they do it. The book then moves on to a brief introduction of the GPRS protocol stack which provides a launch pad for a detailed trip into all the layers of this stack, with detailed diagrams and explanations of each layer integrated into an overall understanding of how the GPRS service operates in practice.Provides descriptions of "why" procedures are specified and then clearly explains how the specifications work in practice Provides a layered view of the GPRS protocol and deals in detail with each layer separately Includes numerous acronyms and abbreviations accompanied by their full meaning

The recent history of Africa is characterised by the 'revolution' in information and communication technologies (ICT), specifically in the sector of mobile telephony, which reconsiders the challenges pertaining to identity in African societies. In this book, we follow the manifestation of such dynamic forces in the Hadjeray society in Guera, Tchad, a society that has suffered a history of political violence, mobility and failures. The study shows the role of the Chadian government in the implementation of ICT and explains how government logics have amplified. Through the analysis of the changes in the economic and social spheres, occurring due to mobile telephony, we discover the identity issues that are also informed by the feeling of fear, which is part of the Chadian history of violence. However, the ways in which the Hadjeray adopt this new technology also leave them with a means to escape the logic of violence and disruption. It is mostly a dynamic force that occurs amongst the youth who, by making use of mobile networks, discover another mode of identification, between the ethnic group and the more global identity, and find through it a political voice.

Jahreswechsel 1991/1992: Zwei neue Rundfunkanstalten in Deutschland wurden geboren, der Ostdeutsche Rundfunk Brandenburg und der Mitteldeutsche Rundfunk - nachtr glich zur deutschen Einheit, kompatibel zum westdeutschen Rundfunksystem. Daf r mussten die berbleibsel der DDR verschwinden, Abwicklung der Einrichtung hie das Politikjargon. Die alten Fernseh- und H rfunksender wurden um 0 Uhr abgeschaltet oder neuen Rundfunkanstalten zugeordnet. War diese politische Entscheidung unausweichlich f r ein Gelingen der Deutschen Einheit? Oder sind dabei Chancen f r Demokratie, Kultur und Identit t vertan worden? Dieser Frage geht Reiner Stein in diesem Buch nach und reflektiert noch einmal die deutsch-deutsche Rundfunkgeschichte von 1989 bis 1992 mit all den Ideen, Konflikten und Kompromissen.

The field of radio communications continues to change rapidly, and the second edition of this outstanding book, based on a popular IEE Vacation School, has been fully updated to reflect the latest developments. The introduction of new services and the proliferation of mobile communications have produced a growing need for wider bandwidths and the consequent need for frequency reuse. This book introduces the basic concepts and mechanisms of radiowave propogation engineering in both the troposphere and ionosphere, and includes greater emphasis on the needs of digital technologies and new kinds of radio systems. The content reflects the wide experience of an exceptional group of authors and the emphasis throughout is on modelling and prediction methods and the relevant ITU Radiocommunication Sector recommendations. Propagation of Radiowaves, 2nd Edition is essential reading for professionals involved in planning, designing and operating radio systems, as well as postgraduate students in the field.

Written by two leading experts in the field, this exceptional book introduces the reader to the principles, theory and applications of physical layer wireless/mobile communications. In the area of wireless, the antennas, propagation and the radio channel used are inter-related; this book offers an explanation of that relationship, which is fundamental to the development of systems with high spectral efficiency. Channels, Propagation and Antennas for Mobile Communications emphasises the basic principles needed to establish an understanding of this technology. However, the tools required - such as the mathematics and statistics - are treated in the manner of a practical handbook, avoiding detailed derivations.

Vast numbers of radio systems are now in use, and with new users and new uses constantly emerging, these systems have the potential to interfere with each other. National agencies are empowered to control the use of radio to ensure that systems within their jurisdiction do not disrupt each other's services. Interference may also arise between radio systems operating in different countries. An elaborate code of regulations has been agreed, under the aegis of the International Telecommunication Union, to facilitate cooperation between the national agencies to control interference across frontiers. The Union also provides the global forum for the standardisation of radio systems where this has been found to be desirable. For some kinds of radio system, especially broadcasting and land mobile radio, governments may also find it necessary to determine which of the organisations competing to provide radio facilities for public use should be licensed and which should not. This process is known as regulation. Intended as a handbook for administrators and engineers, this book reviews the processes of interference management, regulation of competing service providers and system standardisation for the control and use of the radio spectrum. At a time when telecommunication services and broadcasting are being liberalised in many countries, this book will also provide new operators of radio facilities, private and public, with valuable insights into the regulatory process.
