One hundred years ago, the notion of transmitting information without the use of wires must have seemed like magic. In 1896, the first patent for wireless communication was granted to Marchese Guglielmo Marconi. Since then the field of wireless communications which includes cellular systems has taken various forms of development. It basically evolved through three Eras. The Pioneer Era over the period of 1860-1921, the Precellular Era over 1921-1980 and the Cellular Era after 1980 and beyond. The first generation cellular era started with the Analog Systems and evolved in the digital domain utilizing Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA), thus comprising the Second Generation Mobile Systems. The first generation RF cellular communications systems deployed in the early to mid 1980's had air interfaces comprised of analog technology. Among them were AMPS (Advanced Mobile Phone System), NMT (Nordic Mobile Telephone), and TACS (Total Access Communications System). These were designed for use in a specific geographic area and not intended to be deployed in other areas. There was not much commonality beyond using the same air interface technology and same modulation. The air interface technology was Frequency Division Multiple Access (FDMA) and the modulation was analog FM, but with different deviations and channel spacings. The frequency bands, air interface protocols, number of channels, and data rates were different. In general, these systems provided local and national coverage.

The Global System for Mobile Communication (GSM) is undoubtedly the most successful second generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM systems and its derivatives DCS-1800 and PCS-1900. The objective of the book is to address new concepts in the GSM system, dealing with both standardised features as well as theoretically and technologically feasible improvements, which contribute to evolutionary changes in general. Dynamic evolution of GSM presents a platform for the Universal Mobile Telecommunication System (UMTS) introduction and major trends in UMTS development will be addressed in this book, in particular progress towards new radio interface. The book is the collection of individual contributions from a number of authors. The intention of the editors was to gather the most prominent specialist in the GSM area. Ongoing efforts in GSM standardisation are focused on Phase 2+ with items planned to be added gradually on demand. Being mostly independent of each other, each of them could be introduced with little impact on the rest of the system. Speech remains the prime service of cellular systems with ongoing work on spectral efficiency taking into account the trade-off between cost of the system and transmission quality. Most notable result from novel speech service implementations is the introduction of new Enhanced Full Rate (EFR) speech coder. International railway organisation (Union Internationale des Chemins de Fer - UIC) has influenced the development of Advanced Speech Call Items (ASCI).

As the first wave of third-generation communication devices arrives, the technological and societal effects are becoming widespread. The ability to communicate via hand-held devices through voice, data, and video raises many challenges and questions. Besides detailed looks at technological issues, from the system protocol to implementation technologies, this book discusses the administrative and industrial aspects of third-generation mobile communications. The authors emphasize existing problems and propose new solutions. They seek to provide the most comprehensive and topical information on 3G mobile communications currently available. The following chapters offer an overview of wireless technology and terminology, protocols for mobility management, the safety of radio-frequency energy, WLAN (wireless local area networks), multiple access schemes, and microwave photonics. It is intended as an introduction and reference for engineers entering the field of wireless communications.

Get a clear, complete debriefing on the current status of the third generation radio interface technology now being standardized by the international body 3GPP. This timely new work, written by Europe's leading mobile communications researchers from manufacturing, operators, and academia, gives you a thorough explanation of the basic principles of multiple access technologies, including receiver algorithms, coding, and modulation, to help you stay up-to-date with the development of third generation systems. Much of the research presented here originated in the FRAMES (Future Radio Wideband Multiple Access System) Project, which was partly funded by the European Commission. It served as the basis for ETSI's decision to adopt W-CDMA/TD-CDMA as the air interface standard for third generation systems, as well as for the actual specification work in 3GPP.

Multi-carrier technologies have emerged as important instruments in telecommunications. OFDM is in the forefront, with its adoption by the IEEE 802.11 standards committee and the European HYPERLAN standards group. Following OFDM, MC-CDMA is also demonstrating considerable promise when compared to competing technologies. According to the authors, these technologies are just the beginning in the coming multi-carrier revolution. In Multi-Carrier Technologies for Wireless Communication, the authors explain how a common multi-carrier platform is being designed for DS-CDMA, TDMA, OFDM and MC-CDMA systems. Findings are presented which show how this multi-carrier platform enhances network capacity and probability of error performance.Specific results include (1) innovation in multi-carrier technologies that are enabling them to become an integral part of TDMA and DS-CDMA systems; and (2) the design of multi-carrier systems to overcome PAPR problems (in, e.g., OFDM). Multi-Carrier Technologies for Wireless Communication is an important book for engineers who work with DS-CDMA, TDMA, OFDM, or MC-CDMA systems, and are seeking new ways of exploiting the wireless medium based on a "smarter" signal processing.
