The concept of smart cities emerged few years ago as a new vision for urban Development that aims to integrate multiple information and communication technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT infrastructure and e-services should fuel sustainable growth and quality of life, enabled by a wise and participative management of natural resources to be ensured by citizens and government. The need to build smart cities became a requirement that relies on urban Development that should take charge of the new infrastructures for smart cities (broadband infrastructures, wireless sensor networks, Internet-based networked applications, open data and open platforms) and provide various smart services and enablers in various domains including healthcare, energy, education, environmental management, transportation, mobility and public safety.

One traditional view of how wireless networks evolve is of a continuous, inevitable progres- sion to higher link speeds, combined with greater mobility over wider areas. This standpoint certainly captures the Development from first and second generation cellular systems focused on voice support, and the early short-range wireless data networks, through to today’s 3G cellular and mobile broadband systems; there is every confidence that the trend will continue some way into the future.

Mobile communication devices like smart phones or tablet PCs enable us to consume information at every location and at every time. The rapid Development of new applications and new services and the demand to access data in real time create an increasing throughput demand. The data have to be transmitted reliably to ensure the desired quality of service. Furthermore, an improved utilization of the bandwidth is desired to reduce the cost of transmission.

During the past two decades, technological Development related to telecommuni- cation technologies has allowed organizations of all types and size to be able to de- velop effective networking applications in support of information management. Fur- thermore, telecommunication technologies combined with computer technology have created the foundation of modern information technology which has affected all as- pects of societal and organizational functions in our modern world.

Since the telephone was invented in the late nineteenth century, there has been a steady Development of telephone services, and the number of subscribers has con- tinuously increased. One of the most revolutionary Developments in telephone serv- ice in the late twentieth century was the introduction of the cellular variety of mobile phone services.

The genesis for this book was my involvement with the Development of the SystemView (now SystemVue) simulation program at Elanix, Inc. Over several years of Development, technical support, and seminars, several issues kept recur- ring. One common question was, “How do you simulate (such and such)?” The sec- ond set of issues was based on modern communication systems, and why particular developers did what they did. This book is an attempt to gather these issues into a single comprehensive source.

Over the past few decades, wireless communications and networking have witnessed an unprecedented growth, and have become pervasive much sooner than anyone could have predicted. For example, cellular wireless networks are expected to become the dominant and ubiquitous telecommunication means in the next few decades. The widespread success of cellular and WLAN systems prompts the Development of advanced wireless systems to provide access to information services beyond voice such as telecommuting, video conferencing, interactive media, real-time internet gaming, and so on, anytime and anywhere.

Designing for Networked Communications: Strategies and Development is a book about how we plan, use, and understand the products, dynamic social processes, and tasks upon which depend some of the most vital innovations in the knowledge society—social as well as technological ones. Focusing on various forms of design, implementation, and integration of computer-mediated communication (CMC), the book bridges the academic fields of computer science and communication stud- ies.

The design and manufacturing of wireless radio frequency (RF) transceivers has developed rapidly in recent ten yeas due to rapid Development of RF integrated circuits and the evolution of high-speed digital signal processors (DSP). Such high speed signal processors, in conjunction with the Development of high resolution analog to digital converters and digital to analog converters, has made it possible for RF designers to digitize higher intermediate frequencies, thus reducing the RF section and enhancing the overall performance of the RF section.
