The exacting Technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the right package has becomeone of the key considerations for the systemdesigner.

Web technology is not evolving in comfortable and incremental steps, but i s turbulent, erratic, and often rather uncomfortable. It is estimated that the Internet, arguably the most important part of the new Technological environment, has expanded by about 2000 ％ and that is doubling in size every six to ten months. In recent years, the advance in computer and web technologies and the decrease in their cost have expanded the means available to collect and store data. As an intermediate consequence, the amount of information (Meaningful data) stored has been increasing at a very fast pace.

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.

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.

Mobile telecommunications emerged as a Technological marvel allowing for access to personal and other services, devices, computation and communication, in any place and at any time through effortless plug and play. This brilliant idea became possible as the result of new technologies developed in the areas of computers and communications that were made available and accessible to the user.

The last decade proved to be hugely successful for the mobile communications industry, characterised by continued and rapid growth in demand, spurred on by new Technological advances and innovative marketing techniques. Of course, when we refer to mobile commu- nications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the mobile-satellite industry over the last decade, although eventful, has, at times, been more akin to an out of control roller coaster ride.
