Book Description
An essential overview of satellite communications from the organization that sets the international standards Since their introduction in the mid-1960s, satellite communications have grown from a futuristic experiment into an integral part of today's "wired world." Satellite communications are at the core of a global, automatically switched telephony network. Assembled by the International Telecommunication Union--the international organization that sets the standards for this rapidly growing industry--the Handbook on Satellite Communications, Third Edition brings together basic facts about satellite communications as related to the fixed-satellite service (FSS). It covers the main principles, technologies, and operation of equipment in a tutorial form. Updated to include the latest technologies and information, the Third Edition provides both the standards and technical information needed to implement and interact with satellite communication systems, including: * The components and basic characteristics of a satellite communication system * Regulatory considerations and system planning * SDH and ATM satellite transmissions * Analog and digital baseband signal processing and multiplexing * Carrier modulation techniques * Geostationary and non-geostationary systems * Interconnection of satellite and terrestrial networks * LEOS satellite networks and other recent developments As digital modulation and transmission replace analog techniques, and as satellites in non-geostationary and lower-altitude orbits open the way to new applications, satellite communications will continue to grow in use and importance. Everyone involved in the administration and operation of satellite communications will find this a crucial resource.

Book Description
The present state of development of communication technology is characterized by two features, namely the digital representation of all signals transrnitted and processed, irrespective of information type - voice, text, data or images - and the integration of systems and services, this integration only being completely possible using digital technology. The boundaries between switching and transmission are shifting, and functions are being redefined and redistributed between terminals and communication networks. Multiservice terminals - unlike telephones, teleprinters, video data terminals - are designed to handle more than one information type. Lastly, the communication network allows voice, text, data and video information to be transmitted on the same circuit; the user obtains access to this network via a non dedicated "communication socket". The essential features of this Integrated Services Digital Network (ISDN) have been standardized over the last eight years by experts from all over the world under the aegis of the CCITT 1), the international standardizing body of the carriers of public communication networks. All the leading network carriers are working towards ISDN implementation because of the substantial benefits it will offer to users, network carriers and manufacturers alike: Users will obtain additional and advanced services, most of them designated to cater for the growth in non-voice traffic. The ISDN subscriber access will also enable users to operate existing systems more cost-effectively than via various dedicated networks.

Book Description
The Economics of Communication: A Selected Bibliography with Abstracts lists several texts that focus on economics of communication. The book also provides description of every text. The texts are organized according to section. The first section contains texts that discuss the definition of the information/communications aspect of the economy, while the second section deals with various communication industries. Section 3 contains texts that provide economic analysis of some aspects of communications. The fourth section deals with the impact of communications on economic systems, while the fifth section contains texts about international exchange of communications goods and services. The last section contains texts that discuss some political implication of the economics of communication. The book will appeal to readers, professionals, and researchers who are concerned with several issues pertaining to economics and communications.

Book Description
Hardbound. The purpose of this book lies outside the usual framework of studies devoted to technology in a given branch of industry. Its main objective is to show how, in only two decades, the highly specialized telephone switching industry was completely transformed and how it revolutionized its manufacturing processes and its products, a phenomenon largely unknown to the public. The change was so drastic that it has been compared to the metamorphosis of the insect which progresses from the caterpillar phase to that of the butterfly.The second aim of the book is to show how the change occurred within the context of the major electronic revolution of recent decades, following the inventions of the transistor and integrated circuits.
