If you're a mobile communications engineer considering software radio solutions, this practical resource is essential reading. It covers systems design and partitioning all the way from the antenna to the management and control software. Various options for hardware are provided including a look at current and state of the art silicon technologies such as A/D & D/As, DSPs, FPGAs, RCPs, ACMs & digital frequency up/down-converters.

Details the technology of microwave integrated circuits, for design engineers and researchers using planar transmission structures in RF, microwave and millimeter-wave circuits and antenna systems, and for students in electronics and telecommunications engineering courses. Coverage includes theory, analysis, and design of microstrip lines; microstrip discontinuities; slotlines; coplanar lines; and coupled microstrip lines. Includes b&w diagrams. This second edition is extensively updated since the first edition in 1979.

Next Generation Intelligent Networks investigates how service creation is taking on board state-of-the-art distributed object-oriented programming techniques. The book focuses on emerging software architectures for programming and deploying value-added services, and proposes a vision of value-added services in the network of the future. Learn how new initiatives such as Soft switches, JAIN, Parlay, OSA, TINA and CAMEL help you to more effectively handle the new challenges brought on by the rapid growth of cellular mobile networks and the Internet.

This reference offers practical explanations of the full range of radio frequency integrated circuits (RFICs). It focuses mainly on bipolar technology to demonstrate circuits, but CMOS is included as well. By emphasizing working designs, it seeks to transport the reader into the authors' own RFIC lab so that you can understand the function of each design detailed in the text. Among the RFIC designs examined are RF integrated LC-based filters, VCO automatic amplitude control loops, and fully-integrated transformer-based circuits, as well as image reject mixers and power amplifiers.

Internet and wireless technologies are converging towards an exciting future that we've only begun to realize. For professionals who have a background in the Internet or in mobile telephony - but not in both - this integrated "how it works" guide offers a practical understanding of wireless Internet communications, the technology components involved, and how they fit and work together.

The book addresses IPsec’s major aspects and components to help you evaluate and compare features of different implementations. It gives you a detailed understanding of this cutting-edge technology from the inside, which enables you to more effectively troubleshoot problems with specific products. Based on standards documents, discussion list archives, and practitioners’ lore, this one-of-a-kind resource collects all the current knowledge of IPsec and describes it in a literate, clear manner.
