This textbook goes to the heart of telecommunications engineering by developing the underlying concepts and linking them to how system specifications are determined by standards bodies – and how systems are designed and implemented by equipment manufacturers. In this regard, the book is comprehensive in covering all important aspects of wireless networks. Tailored to undergraduate/graduate students and practicing engineers, this book presents the fundamental concepts in a concise manner, while retaining the rigor needed to truly understand wireless communications. Importantly, the book ties these developments to how these concepts are implemented in fielded systems, discussing the motivations behind the design choices made in 4G and 5G wireless communications. The book bridges the gap between theory and application, presenting key practical issues. Presents RF concepts, RAN protocols, and radio planning and optimization; Bridges the gap between theoretical and application-driven textbooks on cellular radio access networks; Includes a full suite of classroom materials including PowerPoint slides, a solutions manual, and tutorials.

This book presents an end-to-end architecture for demand-based data stream gathering, processing, and transmission. The Internet of Things (IoT) consists of billions of devices which form a cloud of network connected sensor nodes. These sensor nodes supply a vast number of data streams with massive amounts of sensor data. Real-time sensor data enables diverse applications including traffic-aware navigation, machine monitoring, and home automation. Current stream processing pipelines are demand-oblivious, which means that they gather, transmit, and process as much data as possible. In contrast, a demand-based processing pipeline uses requirement specifications of data consumers, such as failure tolerances and latency limitations, to save resources. Our solution unifies the way applications express their data demands, i.e., their requirements with respect to their input streams. This unification allows for multiplexing the data demands of all concurrently running applications. On sensor nodes, we schedule sensor reads based on the data demands of all applications, which saves up to 87% in sensor reads and data transfers in our experiments with real-world sensor data. Our demand-based control layer optimizes the data acquisition from thousands of sensors. We introduce time coherence as a fundamental data characteristic. Time coherence is the delay between the first and the last sensor read that contribute values to a tuple. A large scale parameter exploration shows that our solution scales to large numbers of sensors and operates reliably under varying latency and coherence constraints. On stream analysis systems, we tackle the problem of efficient window aggregation. We contribute a general aggregation technique, which adapts to four key workload characteristics: Stream (dis)order, aggregation types, window types, and window measures. Our experiments show that our solution outperforms alternative solutions by an order of magnitude in throughput, which prevents expensive system scale-out. We further derive data demands from visualization needs of applications and make these data demands available to streaming systems such as Apache Flink. This enables streaming systems to pre-process data with respect to changing visualization needs. Experiments show that our solution reliably prevents overloads when data rates increase.

Radio Technologies and Concepts for IMT-Advanced presents the findings of the Wireless World Initiative New Radio (WINNER) project in Framework Program 6 of the European Commission. It provides an insight into the key concepts and technologies for the IMT-Advanced radio interface, based on the collaborative research of manufacturers, network operators, research centres and universities within WINNER. The book covers the fundamental radio characteristics of a typical 4G wireless communication system, focusing on the transceiver’s chain from the physical layer to layers 2 and 3. Starting by defining realistic and futuristic usage scenarios, the authors provide in-depth discussion of key technologies including modulation and coding, link level procedures, spatial-temporal processing, multiple access schemes and inter-cell interference mitigation, channel estimation and newly developed channel models. Finally, a cost assessment and optimisation methodology is developed for different deployment concepts in order to assess a wireless system in a condition close to reality. The book provides an important system-level approach to the latest radio technologies in the field, and evaluates IMT-Advanced research in relation to international standardisation. Presents the research findings of IMT-Advanced radio interface from the WINNER project Covers the latest concepts for relaying, multiple access, radio resource control, flexible spectrum use, and ITU-R spectrum demand calculation Examines the most recent Multiple-Input, Multiple-Output (MIMO) techniques, and Distributed Antenna Systems (Coordinated Multipoint Transmissions) Describes a 4G system concept and all major building blocks Provides 4G propagation models and system-level evaluation methodologies
