The key feature of future mobile communication systems is the ability to deliver wideband and high bit-rate multimedia services alongside the traditional radio services such as voice, messaging and slow rate data. The broad range of services expected to be supported can be divided into different Quality of Service (QoS) classes. However, the provision of such mobile multimedia services under QoS guarantees will not be possible without a utilization of the air interface resources by means of Radio Resource Management (RRM) strategies that ensure the target QoS, the planned coverage area and that offer a high system capacity. Under this framework, the book focuses on the RRM concepts, including the theoretical background that serves as a basis for the description of specific RRM algorithms. The RRM problem for UMTS is presented, and more specifically, for the FDD mode, which is based on a WCDMA scheme. More specifically, the different aspects that are covered include: Introduces the mobile communications sector and UMTS, including the evolution towards 4G systems, with an overview of the QoS concept which is key for the definition of RRM strategies Offers a detailed description of the radio interface in UMTS, as the basis for the implementation of RRM strategies Provides the fundamental concepts related with the development of RRM strategies in WCDMA networks Analyses particular RRM algorithms in a variety of scenarios, trying to identify the key parameters and factors that influence their performance Explores the evolution of UMTS towards Beyond 3G systems and the concept of Common RRM in heterogeneous networks with the aid of some algorithm examples This comprehensive title is essential reading for engineers and managers in radio engineering departments of UMTS network operators and UMTS equipment manufacturers. It will also prove insightful to researchers in the field of 3G and Beyond 3G systems and academics in any of these areas.

Beyond 2020, wireless communication systems will have to support more than 1,000 times the traffic volume of today's systems. This extremely high traffic load is a major issue faced by 5G designers and researchers. This challenge will be met by a combination of parallel techniques that will use more spectrum more flexibly, realize higher spectral efficiency, and densify cells. Novel techniques and paradigms must be developed to meet these goals. The book addresses diverse key-point issues of next-generation wireless communications systems and identifies promising solutions. The book's core is concentrated to techniques and methods belonging to what is generally called radio access network.

Recent spectacular achievements in wireless, mobile, and sensor networks have dramatically changed our lives in many ways. However, the rapid evolution of wireless systems not only promises increased functionality, reliability, availability, and security, as well as putting a wide variety of new services at the users’ disposal ? it also creates a number of design challenges that our research community is now facing. Scientists and engineers need to come up with, and promptly implement, novel wireless network architectures, while system operators and planners rethink their business models and attend to the growing expectations of their customer base. To provide a suitable forum for discussion between researchers, practitioners, and industry representatives interested in new developments in the respective research area, IFIP WG 6. 8 launched three separate series of conferences: MWCN (Mobile and Wireless Communications Networks), PWC (Personal Wireless Communications), and WSAN (Wireless Sensor and Actors Networks). In 2008, MWCN and PWC were merged into the IFIP Wireless and Mobile Networking Conference (WMNC 2008), held in Toulouse, France, from September 30 to October 2, 2008. MWNC 2008 and PWC 2008 topics were subsequently revised with a view to covering the whole spectrum of hot issues in wireless and mobile networking. As a result, IFIP WG 6. 8 decided to add WSAN as another WMNC track.

Heterogeneous wireless networking, which is sometimes referred to as the fourth-generation (4G) wireless, is a new frontier in the future wireless communications technology and there has been a growing interest on this topic among researchers and engineers in both academia and industry. This book will include a set of research and survey articles featuring the recent advances in theory and applications of heterogeneous wireless networking technology for the next generation (e.g., fourth generation) wireless communications systems. With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third generation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. Fourth generation (4G) wireless systems are devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously. This book intends to provide a unified view on the state-of-the-art of protocols and architectures for heterogeneous wireless networking. The contributed articles will cover both the theoretical concepts and system-level implementation issues related to design, analysis, and optimization of architectures and protocols for heterogeneous wireless access networks.
