Download or read book Provision of Cordless Telecommunications Services Using the Dect Standard of Cordless Telecommunications Services Using the Dect Standard written by Theologos N. Kanaropoulos and published by . This book was released on 1993 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cordless telecommunications has become the focus of much research effort across Europe during the last six years in response to the widely recognised need for a new generation of digital radio systems to meet demand in the European single market for telecommunications products and services. The culmination of this effort will be the definition of a standard for Digital European Cordless Telecommunications (DECT) by the European Telecommunications Standards Institute (ETSI) and a first release of this standard has now been agreed. However, the standard is necessarily complex in order to accommodate the range of services which DECT terminals will need to support and the implementation of the standard in future products and the deployment of DECT systems in different operational environments remain important areas for further research. This thesis deals with the principal aspects of this problem through the medium of simulation by exploring in detail those features of the air-interface which are concerned with the radio access and the teletraffic service support. The simulator, described in Chapter 2, is designed for maximum flexibility in investigating many possible combinations of radio propagation environment, equipment characteristics, traffic demands and geographical configuration of base stations and user terminals. In the following Chapter, the effects of modifications to a wide range of call parameters are systematically investigated and the results used to establish performance bounds for DECT systems. Chapters 4 and 5 represent the major contribution to knowledge generated by the research. In Chapter 4 the simulator is used to investigate how various service requirements can be met within the framework of the DECT standard. Particular attention is devoted to ISDN compatibility for different combinations of voice and data traffic including full and half rate speech coding, 'homogenous' and 'heterogeneous' connections and asymmetric traffic requirements such as FAX. On the basis of this study, Chapter 5 tackles the problem of optimising the algorithms which may be implemented in future DECT systems to maximise system capability in the many different operating.

Download or read book Cordless Telecommunications in Europe written by Wally H.W. Tuttlebee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mobile telecommunications industry is experiencing consider able growth at present and with the increased traffic capacities which these systems provide and falling equipment prices, it is expected to continue to grow throughout the 1990s. Projections of equipment costs indicate that even portable cellular handsets could come within the reach of many customers well before the end of the century. This will transform mobile communications services from a minority, high cost application into a mainstream telecommunications service. For both market and technical reasons it is likely that the distinction between cellular, Telepoint and paging services will decrease, and the provision of common hardware in the form of a Universal Personal Communicator will become increasingly feasible. 1987 Green Paper on The European Commission's June Telecommunications included the proposal to create a European Telecommunications Standards Institute (ETSI). This has resulted in a major reform of the European standards-setting process with the establishment of ETSI in March 1988 in Sophia-Antipolis, Nice, France. In the field of cordless telecommunications, ETSI has charged its Technical Sub-Committee RES 3 with producing the Digital European Cordless Telecommunications (DECT) standard by October 1991. In the meantime, the UK CT2 Common Air Interface (CAl) has been agreed by ETSI RES in March 1990 as the basis for an Interim European Telecommuni cations Standard (I-ETS) for Telepoint applications within Europe.

Download or read book Service Provision written by Kenneth J. Turner and published by John Wiley & Sons. This book was released on 2005-01-28 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first overview of the service technologies available to telecoms operators working in a post-convergence world. Previous books have focused either on computer networks or on telecoms networks. This is the first to bring the two together and provide a single reference source for information that is currently only to be found in disparate journals, tool specifications and standards documents. In order to provide such broad coverage of the topic in a structured and logical fashion, the book is divided into 3 parts. The first part looks at the underlying network support for services and aims to explain the technology that makes the user-visible services possible. This section covers multimedia networking, both traditional (legacy) and future (softswitch) call processing, intelligent networks, the Internet, and Wireless networks. Part 2 deals with how these services may be analysed and managed. Chapters cover topics such as commercial issues, service management, quality of service, security, standards and APIs. Part 3 concludes the book by looking ahead at evolving technologies and more speculative possibilities, discussing the kinds of services that may be possible in the future and the technologies that will support them. * Focuses is on how the technology supports the services, rather than on technology for its own sake * Contributors drawn from both academia and industry (companies such as Marconi, BT, Telcordia, Cisco, Analysys) to give both theoretical and real-world perspectives * Unique singe-reference source for a wide range of material currently found only in disparate papers, specs and documentation * Covers brand new technologies such as JAIN, JTAPI, Parlay, IP, multimedia networking, active networks, WAP, wireless LANs, agent-based services, etc.

Download or read book Wireless Communication the fundamental and advanced concepts written by Sanjay Kumar and published by CRC Press. This book was released on 2022-09-01 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication is one of the fastest growing fields in the engineering world today. Rapid growth in the domain of wireless communication systems, services and application has drastically changed the way we live, work and communicate. Wireless communication offers a broad and dynamic technological field, which has stimulated incredible excitements and technological advancements over last few decades. The expectations from wireless communication technology are increasing every day. This is placing enormous challenges to wireless system designers. Moreover, this has created an ever increasing demand for conceptually strong and well versed communication engineers who understand the wireless technology and its future possibilities. In recent years, significant progress in wireless communication system design has taken place, which will continue in future. Especially for last two decades, the research contributions in wireless communication system design have resulted in several new concepts and inventions at remarkable speed. A text book is indeed required to offer familiarity with such developments and underlying concepts, to be taught in the classroom to future engineers. This is one of the motivations for writing this book. Practically no book can be up to date in this field, due to the fast ongoing research and developments. The new developments are announced almost every day. Teaching directly from the research papers in the classroom cannot build the necessary foundation. Therefore need for a textbook is unavoidable, which is integral to learning, and is an essential source to build the concept. The prime goal of this book is to cooperate in the learning process.

Download or read book Wireless Communication in Underground Mines written by L. K. Bandyopadhyay and published by Springer Science & Business Media. This book was released on 2009-08-29 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.
