Space Division Multiple Access is one of the most promising methods in solving the capacity problem of wireless communication systems. This book defines formulae that can be used to evaluate the limit capacity of multipath wireless channels in a particular receiving region with size limitation.

New paradigms for communication/networking systems are needed in order to tackle the emerging issues such as heterogeneity, complexity and management of evolvable infrastructures. In order to realize such advanced systems, approaches should become task- and knowledge-driven, enabling a service-oriented, requirement, and trust-driven development of communication networks. The networking and seamless integration of concepts, technologies and devices in a dynamically changing environment poses many challenges to the research community, including interoperability, programmability, management,...

A plumber makes house calls all morning only to return to his shop to pick up messages for the afternoon.

A rural farmer wants to know what crop prices are in the market to see when best to sell his crops - he has to take a day out to visit the market only to find out that the prices are too low midweek.

This was Africa before mobile phones arrived: a lot of walking and not much talking. In the main, fixed line phones were provided by a monopoly provider and were...

A discussion of recently developed experimental methods for noise research in nanoscale electronic devices, conducted by specialists in transport and stochastic phenomena in nanoscale physics. The approach described is to create methods for experimental observations of noise sources, their localization and their frequency spectrum, voltage-current and thermal dependences. Our current knowledge of measurement methods for mesoscopic devices is summarized to identify directions for future research, related to downscaling effects.

The directions for future research into fluctuation...

High Speed Packet Access (HSPA) is a collection of two mobile telephony protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA). Allowing networks based on the Universal Mobile Telecommunications System to achieve data rates of several megabits per second, these powerful protocols are ideal for applications ranging from file transfer to multimedia streaming.

From basic concepts to research grade material, the HSDPA/HSUPA Handbook provides technical information on all aspects of HSDPA/HSUPA. With contributions from 30...

In this book, the authors describe how to perform multicast, the one-to-many delivery of data to a group of destinations, in third-generation mobile networks.

The authors provide an overview of the services that can be realized with multicast in third-generation networks, describe the mechanisms required to support these services and highlight the performance of several multicast mechanisms. The focus of this book is on multicast in UMTS and CDMA2000 networks, the dominant third-generation network standards. In addition to...

This book is invaluable in enabling wireless operators to extract...

A Practical Approach To Antenna Technology For Communication Satellites

This authoritative resource discusses antenna technology for communication satellites, addressing both the space and user segments. The book provides a system view of antenna applications, a description of various antenna technologies, and guidance on methodologies for antenna evaluation.

Communication Satellite Antennas begins with an overview of the parameters that characterize antennas, and goes on to cover the antenna designs, technologies, and system architectures required...

In an emergency, availability of the pervasive communications environment could mean the difference between life and death. Possibly one of the first guides to comprehensively explore these futuristic omnipresent communications networks, the Pervasive Communications Handbook addresses current technology (i.e., MAC protocols and P2P-based VoD architecture) and developments expected in the very near future, when most people and places will be virtually connected through a constant and perpetual exchange of information. This monumental advance in communications is set to...

Addressing the most dynamic areas of the ever-changing telecommunications landscape, the second edition of the bestselling CRC Handbook of Modern Telecommunications once again brings together the top minds and industry pioneers in wireless communication networks, protocols, and devices.

In addition to new discussions of radio frequency identification (RFID) and wireless sensor networks, including cognitive radio networks, this important reference systematically addresses network management and administration, as well as network organization and governance,...

Design and Analysis of High Efficiency Line Drivers for xDSL covers the most important building block of an xDSL (ADSL, VDSL, ...) system: the line driver. Traditional Class AB line drivers consume more than 70% of the total power budget of state-of-the-art ADSL modems. This book describes the main difficulties in designing line drivers for xDSL. The most important specifications are elaborated staring from the main properties of the channel and the signal properties. The traditional (class AB), state-of-the-art (class G) and future technologies (class K) are discussed.

The main...
