The first book to cover all engineering aspects of microwave communication path design for the digital age Fixed point-to-point microwave systems provide moderate-capacity digital transmission between well-defined locations. Most popular in situations where fiber optics or satellite communication is impractical, it is commonly used for cellular or PCS site interconnectivity where digital connectivity is needed but not economically available from other sources, and in private networks where reliability is most important. Until now, no book has adequately treated all engineering aspects of microwave communications in the digital age. This important new work provides readers with the depth of knowledge necessary for all the system engineering details associated with fixed point-to-point microwave radio path design: the why, what, and how of microwave transmission; design objectives; engineering methodologies; and design philosophy (in the bid, design, and acceptance phase of the project). Written in an easily accessible format, "Digital Microwave Communication" features an appendix of specialized engineering details and formulas, and offers up chapter coverage of: A Brief History of Microwave RadioMicrowave Radio OverviewSystem ComponentsHypothetical Reference CircuitsMultipath FadingRain FadingReflections and ObstructionsNetwork Reliability CalculationsRegulation of Microwave Radio NetworksRadio Network Performance ObjectivesDesigning and Operating Microwave SystemsAntennasRadio DiversityDucting and Obstruction FadingDigital Receiver InterferencePath Performance Calculations "Digital Microwave Communication: Engineering Point-to-Point Microwave Systems" will be of great interest to engineers and managers who specify, design, or evaluate fixed point-to-point microwave systems associated with communications systems and equipment manufacturers, independent and university research organizations, government agencies, telecommunications services, and other users.

Wireless communications technologies are the platform to develop user-centric systems in a multi-device platform that allows mobility and user-friendly interaction. The development of a multi-device platform requires a common language such as Java. This book discusses two different works related with Bluetooth and GPS-GSM communication, to illustrate the capacity of Java language to develop applications that need wireless communications. Java application on the distributed system is introduced by certain keywords, design pattern, software architecture, design process and architecture for ubiquitous space. Furthermore, Java is often used as an embedded programming system, which is a combination of hardware, software, mechanical and other technical components designed to perform a dedicated function, unlike a general purposes computer. This book describes a new development framework for embedded control systems and engine calibration is presented, which supports the modelling of such systems and provides tools for the design and validation activities. An analytical method to express the resonant frequency in terms of the lumped component values is outlined as well.

Next generation wireless and mobile communication systems are rapidly evolving to satisfy the demands of various network users. Due to the great success and enormous impact of IP networks, high-speed transmission is now possible for both indoor and outdoor wireless systems, internet access and web browsing have become the ruling paradigm for next generation system. It is envisioned that new generation wireless networks and hand-held terminals will support a wide variety of multimedia services such as multimedia web browsing, video and news on demand, mobile office system, stock market information, and so on, to mobile users anywhere, anytime in an uninterrupted and seamless way with low-powered handsets. The characteristics of wireless links, as well as the desire to maintain connectivity while on the move, offer significant challenges to provisioning quality of service and the related performance is of central interest. Since the resources (such as time, frequency and code) in the wireless segments of such networks are very limited, over-dimensioning the network resource is equivalent to poor capital investment, while congestion at busy hours could mean lost calls and lost revenues. It is therefore critical for wireless network designers to utilise these resources efficiently and effectively. In response to the above demand for next generation wireless and mobile communication systems, this book aims at providing a timely and concise reference of the current activities and findings in the relevant technical fields. The primary goal is to address the key technical issues pertaining to the integrated new systems and present novel technical contributions. The book contains 14 invited chapters from prominent researchers working in this area around the world.

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.
