The evolution of mobile communication standards presents numerouschallenges in mobile handset design. Designers must continue toturn out handsets that maintain high device performance and airinterface compatibility, while at the same time shrink powerconsumption, form factors, and costs. Mobile Handset Design is uniquely written to equipprofessionals and students with a complete understanding of how amobile phone works, and teaches the skills to design the latestmobile handsets. Das walks readers through mobile phone operatingprinciples, system infrastructure, TDMA-FDMA-CDMA-OFDMA techniques,hardware anatomy, software and protocols, and internal modules,components, and circuits. He presents all problems associated withmobile wireless channels and recommends corresponding designsolutions to overcome those issues. Mobile RF front-end, digitalbaseband design techniques, and associated trade-offs are alsocovered. Das also discusses the productization aspects and reviewsnew research developments for different mobile phone systems overgenerations. Teaches basic working principles of legacy and 4G mobilesystems Vividly illustrates and explains all key components and theanatomy of mobile phones Explains all hardware and software blocks, from principle topractice to product Discusses key design attributes such as low power consumptionand slim form factors Moves through all topics in a systematic fashion for easycomprehension Presentation files with lecture notes available for instructoruse This book is essential for practicing software, hardware and RFdesign engineers and product managers working to create innovate,competitive handsets. Mobile Handset Design is also idealfor fresh graduates or experienced engineers who are new to themobile industry, and is well-suited for industry veterans as ahandy reference.

Comprehensive reference to successful service design for the telecommunications industry Telecommunications companies operate in increasingly competitive environments. The companies that survive and excel are those offering the most compelling range of products and services. These services are complex since they touch all aspects of business. Service design and implementation skills are therefore the key for staying on top of the competition. Successful Service Design for Telecommunications provides a comprehensive guide into service design and implementation. The author provides a consistent approach to designing scalable and operable processes that can be used when designing a variety of technologically based services; offering concepts, principles and numerous examples that the readers can easily adapt to their technological environment. Key features: Defines what telecommunications services are from business, technical and operational perspectives Explains how telecommunications services can be implemented, including implementation strategies for both new service introductions and enhancements to existing services The principles and management processes described can be used on all telecommunications services (fixed, mobile, broadband and wireless) and technology (e.g. IT and Internet) based services Includes references to the current best practices and industry standards and complements the eTom and the OSS/ BSS models proposed by the TeleManagement Forum Features numerous real-life scenarios and examples to support the discussion on the key concepts of service design This book will be of interest to managers, service designers, project managers, IT professionals, operation managers and senior executives who work in the telecommunications sector. University students studying telecommunications, IT and service science courses will also find this text insightful.

A highly practical guide rooted in theory to include the necessary background for taking the reader through the planning, implementation and management stages for each type of cellular network. Present day cellular networks are a mixture of the technologies like GSM, EGPRS and WCDMA. They even contain features of the technologies that will lead us to the fourth generation networks. Designing and optimising these complex networks requires much deeper understanding. Advanced Cellular Network Planning and Optimisation presents radio, transmission and core network planning and optimisation aspects for GSM, EGPRS and WCDMA networks with focus on practical aspects of the field. Experts from each of the domains have brought their experiences under one book making it an essential read for design practitioners, experts, scientists and students working in the cellular industry. Key Highlights Focus on radio, transmission and core network planning and optimisation Covers GSM, EGPRS, WCDMA network planning & optimisation Gives an introduction to the networks/technologies beyond WCDMA, and explores its current status and future potential Examines the full range of potential scenarios and problems faced by those who design cellular networks and provides advice and solutions all backed up with real-world examples This text will serve as a handbook to anyone engaged in the design, deployment, performance and business of Cellular Networks. "Efficient planning and optimization of mobile networks are key to guarantee superior quality of service and user experience. They also form the essential foundation for the success of future technology development, making this book a valuable read on the road towards 4G." —Tero Ojanperä, Chief Technology Officer, Nokia Networks

Bridging the industry divide between the technical expertise of engineers and the aims of market and business planners, Making Telecoms Work provides a basis for more effective interdisciplinary analysis of technology, engineering, market and business investment risk and opportunity. Since fixed and mobile broadband has become a dominant deliverable, multiple areas of transition and transformation have occurred; the book places these changes in the context of the political, social and economic dynamics of the global telecommunications industry. Drawing on 25 years of participative experience in the mobile phone and telecommunications industry, the author closely analyses the materials, components and devices that have had a transformative impact. By presenting detailed case studies of materials innovation, such as those shown at success story Apple, the book shows how the collaboration of technological imagination with business knowledge will shape the industry’s future. Makes a link between the technical aspects and the business practice of the telecoms industry, highlighting the commercial and economic significance of new developments Gives a historical analysis of past successes and failures in order to identify future competitive advantage opportunities Supplies detailed case studies of supply chain disconnects and the impact these have on industry risk and profitability Brings together technological detail with analysis of what is and is not commercially important, from the implications of energy and environmental networks to the technical details of wireless network hardware.
