El presente libro ha sido diseñado para ayudar a los estudiantes del Grado en Ingeniería de Tecnologías de Telecomunicación en el empleo de las herramientas utilizadas en las prácticas de las asignaturas de comunicaciones móviles, y para mostrarles cómo analizar y entender los resultados que se obtienen con dichas herramientas. Para ello, en primer lugar el libro describe de forma didáctica cómo utilizar las herramientas de medida profesionales empleadas en las prácticas de comunicaciones móviles en la UMH. Dichas herramientas se emplean habitualmente por ingenieros de planificación radio para monitorizar en tiempo real el rendimiento de las redes de comunicaciones móviles mediante drive tests. Dicha descripción incluye una presentación detallada de la herramienta de testeo profesional Nemo Handy desarrollada por Anite. Dicha herramienta se incluye en un terminal celular en modo ingeniería, empleado para monitorizar en tiempo real el funcionamiento y rendimiento de las redes celulares, y tomar medidas para su posterior análisis. Dicho análisis se realiza empleando la herramienta Nemo Outdoor, descrita con detalle también en el libro, incluyendo ejemplos sobre cómo realizar los procesados más relevantes. Finalmente, el libro incluye y analiza una serie de medidas se han realizado en un sistema celular UMTS/HSDPA en activo en Elche. En particular, se explica el proceso seguido para realizar dichas medidas empleando Nemo Handy, y se analizan mediante Nemo Outdoor las principales funcionalidades de un sistema celular, como el establecimiento y finalización de llamadas, la selección y re-selección de celdas, el traspaso y el análisis de las descargas de datos y parámetros radio. This book has been designed to guide the students of the Bachelor's in Telecommunications Technology Engineering towards a clear understanding of how to use the laboratory tools, and show them how to analyze and understand the collected measurements. In this context, the book first introduces and describes how to use the professional measurement tools employed in the laboratory activities of the mobile communications course at UMH. These tools are commonly used by cellular radio engineers to monitor in real-time the performance of cellular networks through drive tests. The book first presents the Nemo Handy professional measurement testing tool developed by Anite. This tool is included in an engineering-mode cellular handset used to monitor in real-time the operation of cellular networks, and collect measurements for post-processing. Such processing is done using the Nemo Outdoor tool that is also introduced in the book, including examples of how to perform the most relevant processing actions. Finally, this book shows how to conduct some measurement and analysis processes using Nemo Handy and Nemo Outdoor. The measurements have been conducted over live UMTS and HSDPA networks in the city of Elche, and cover the analysis of important cellular functionalities like establishment and release of a call, cell selection and reselection, handovers, and analysis of data downloads and cellular parameters. This chapter shows with practical examples how to conduct the measurements using Nemo Handy, and how to interpret with Nemo Outdoor the exchanged cellular signaling messages in order to monitor the operation of cellular networks.

This extensively updated second edition of LTE Signaling, Troubleshooting and Performance Measurement describes the LTE signaling protocols and procedures for the third generation of mobile communications and beyond. It is one of the few books available that explain the LTE signaling messages, procedures and measurements down to the bit & byte level, and all trace examples are taken for a real lab and field trial traces. This book covers the crucial key performance indicators (KPI) to be measured during field trials and deployment phase of new LTE networks. It describes how statistic values can be aggregated and evaluated, and how the network can be optimized during the first stages of deployment, using dedicated examples to enhance understanding. Written by experts in the field of mobile communications, this book systematically describes the most recent LTE signaling procedures, explaining how to identify and troubleshoot abnormal network behavior and common failure causes, as well as describing the normal signaling procedures. This is a unique feature of the book, allowing readers to understand the root cause analysis of problems related to signaling procedures. This book will be especially useful for network operators and equipment manufacturers; engineers; technicians; network planners; developers; researchers; designers; testing personnel and project managers; consulting and training companies; standardization bodies.

Research over the last decade has brought about the development of high-performance systems such as powerful workstations, sophisticated computer graphics, and multimedia systems such as real-time video and speech recognition. A significant change in the attitude of users is the desire to have access to this computation at any location without the need to be connected to the wired power source. This has resulted in the explosive growth of research and development in the area of wireless computing over the last five years. Technologies for Wireless Computing deals with several key technologies required for wireless computing. The topics covered include reliable wireless protocols, portable terminal design considerations, video coding, RF circuit design issues and tools, display technology, energy-efficient applications, specific and programmable design techniques, energy efficiency metrics, low-voltage process technology and circuit design considerations, and CAD tools for low-power design at the behavior, logic and physical design level. Technologies for Wireless Computing is an edited volume of original research comprising invited contributions by leading researchers. This research work has also been published as a special issue of the Journal of VLSI Signal Processing Systems (Volume 13, Numbers 2 & 3).
