![]() Since the development of the first wireless systems, great technological advances were performed: spread spectrum and multi-carrier techniques allowed to make transmissions over larger bandwidths with higher data rates for the final users in challenging scenarios where line of sight is not guaranteed and multipath severely affects signal propagation new coding techniques were developed to increase the efficiency of radio transmissions advanced link adaptation and power control algorithms were implemented in order to allow optimized trade-off between reliability and data rate and many other topics shall be cited. This brought to the large interest and great evolution that characterized radio technologies in the last years all over the world. And the need for wireless connections starts from daily communication and embraces all fields of human life, in an ever increasing way: transportation systems, home management, healthcare, emergency operations. Relaying and cooperation among devices will allow better performance with lower costs and energy consumption. The adoption of multiple antennas and beamforming techniques will reduce the effects of interference and increase the achievable data rates. In the near future, all available technologies will be jointly used by smart devices, following the always best connected paradigm: users will connect to an heterogeneous wireless network, without the need to know which technology they are effectively using. But the need for higher data rates does not stop and it jointly proceeds with the development of new services, thus requiring the investigation and implementation of new technologies and new radio resources management solutions. Advanced techniques for the radio resource management will be discussed both in single and multiple radio technologies either in infrastructure, mesh or ad hoc networks. Various aspects will be deeply discussed: channel modeling, beamforming, multiple antennas, cooperative networks, opportunistic scheduling, advanced admission control, handover management, systems performance assessment, routing issues in mobility conditions, localization, web security. In this book, an overview of the major issues faced today by researchers in the field of radio communications is given through 35 high quality chapters written by specialists working in universities and research centers all over the world. WiLab has expertise in the field of telecommunications systems with particular emphasis on wireless systems research activity is mainly performed within the context of important national and international projects, in relation with some of the most important.radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying.Manufacturers and service providers, and in strict cooperation with colleagues coming from the main universities in Europe and United States. Radio-communications architecturesAntoine Diet, Martine Villegas, Geneviève Baudoin and Fabien Robert2. It must be remarked that this book was possible thanks to the valuable work of all authors involved and to the IN-TECH technical staff.Contents Preface 1. Although these pages will not cover all the aspects of such a wide topic, the reader will find a helpful overview on what is happening now and what is expected in an early future in the field of radio communications. More precisely, the physical layer aspects are discussed through chapters 1 to 10, with particular emphasis to MIMO systems from chapter 11 to chapter 18, data link layer and radio resource management are handled without focusing to a specific technology: backward error correction, scheduling, relaying a deeper investigation of systems performance, with particular reference toWiMAX andWiFi systems, is then given through chapters 19 to 25 heterogeneous wireless networks are then examined through chapters 26 to 29 the cross-layer issues of localization and web security, which are of increasing interest in modern wireless technologies, are finally discussed in the remaining part of the book.
