Book Description
In order to meet demands in mobile broadband and to bridge the digital divide a new technology, namely WiMAX, was introduced in 2004. However, in order to increase the financial return on the investment inWiMAX, service operators need to make every effort in designing and deploying the most cost-effective networks. This thesis presents a novel dimensioning technique for WiMAX technology which takes the dimensioning problem to a new level and produces more accurate results in comparison to the traditional methods. Furthermore, a novel decomposed optimization framework for the WiMAX network planning is introduced which subdivides the overall problem into three distinct stages consisting of the network dimensioning stage which besides the primary task of evaluating the financial requirements produces a good starting network solution for the subsequent stages (Stage 1), initial sectorization and configuration of the network (Stage 2) and final network configuration (Stage 3). The proposed framework also solves two fundamental problems, which are cell planning and frequency planning, simultaneously. The feasibility of the final network solutions are then evaluated by OPNET simulator.

Book Description
This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design. These points are equally relevant and applicable in today’s world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.

Book Description
The book brings together a number of theoretical topics necessary for the understanding of wireless network design, optimization techniques, and performance analysis and evaluation. The author takes a practical approach in explaining the material presented, the primary aim being to introduce readers to the art of network design, optimization, and performance analysis. To achieve that aim, the author presents the relevant technological background necessary for understanding those processes. Historically, LTE became the technology of choice for large operators, WiMAX the technology of choice of aviation and smart grids whilst WLAN is a strong candidate for becoming the base for the next generation. The offering of three similar (OFDM based) but different technologies led to a marketing war, announcing spectacular performances that made it difficult to separate reality from marketing claims. This welcome Second Edition provides the foundation which allows readers to understand the basic premises of the technology and to distinguish what is a marketing claim and what is possible to obtain in real life. This second edition presents an in-depth analysis of the technologies evolution and considers the proposed path of the next generation (5G) technology. The book is structured into five main parts: The fundamentals, useful as a refresher and to cover Mathematics Applied to Wireless, Signal Processing Fundamentals, and OFDM; The Wireless Communication Channel, an exclusive in-depth analysis which explains the causes and effects of RF impairments; Data Transmission Protocols Internet History and Modeling, an in-depth examination of data modeling and transmission protocols, including Internet Network, Protocols, Routing, Traffic and Throughput; 4G and 5G Technologies, Network Architectures, Wireless LAN, WiMAX/ WIMAX 2.2, LTE/ LTE-A; Designing a 4G/5G Wireless Network, including Preparing a Business Plan, Design Tasks, and Modeling a Wireless Market

Book Description
This book sets out to provide the theoretical foundations that will enable radio network planners to plan model and optimize radio networks using state-of-the-art findings from around the globe. It adopts a logical approach, beginning with the background to the present status of UMTS radio network technology, before devoting equal coverage to planning, modelling and optimization issues. All key planning areas are covered, including the technical and legal implications of network infrastructure sharing, hierarchical cell structure (HCS) deployment, ultra-high-site deployment and the benefits and limitations of using computer-aided design (CAD) software. Theoretical models for UMTS technology are explained as generic system models, stand-alone services and mixed services. Business modelling theory and methods are put forward, taking in propagation calculations, link-level, UMTS static and UMTS dynamic simulations. The challenges and goals of the automated optimization process are explored in depth using cutting-edge cost function and optimization algorithms. This theory-based resource containing prolific illustrative case studies explains the reasons for UMTS radio networks performance issues and how to use this foundational knowledge to model, plan and optimize present and future systems.
