Book Description
Essay aus dem Jahr 2012 im Fachbereich Ingenieurwissenschaften - Nachrichten- und Kommunikationstechnik, ( Middlesex University in London ), Sprache: Deutsch, Abstract: WiMAX as an alternative technology of the wireless broadband internet service provider technique and Radio over Fiber (RoF) as a technique that employs fiber optic communication technologies to transmit radio-frequency (RF) modulated standard signals for today's wireless and mobile applications. Green radio communication means that the power consumption of the communication systems could be minimized by removing some of the electrical active components and equipment by replacing the passive photonic devices and centralizing the signal processing. We have proposed and demonstrated the improvement of WiMAX power efficiency in green communication by utilizing a radio over fiber system. The simulation has been presented for a WiMAX signal transmitted through single mode fiber optic for 80Km and 5Km on the air. The demonstration results show high Signal-to-Noise-Ratio (SNR), extensive power reduction of up to 90% in WiMAX-RoF and a high power loss of WiMAX signal deployed through air.

Book Description
The evolution of broadband access networks toward bimodal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. After discussing the economic impact of broadband access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are reviewed. State-of-the-art GPON and EPON fiber access networks are described, including their migration to next-generation systems such as OCDMA and OFDMA PONs. The latest developments of wireless access networks are covered, including VHT WLAN, Gigabit WiMAX, LTE and WMN. The advantages of FiWi access networks are demonstrated by applying powerful network coding, heterogeneous optical and wireless protection, hierarchical frame aggregation, hybrid routing and QoS continuity techniques across the optical-wireless interface. The book is an essential reference for anyone working on optical fiber access networks, wireless access networks or converged FiWi systems.

Book Description
The emergence of bandwidth-intensive Internet services creates a high demand for a very qualified next-generation access network. The future access networks should provide high bandwidth, improved network availability, flexibility, mobility, reliability, failure protection, Quality of Service (QoS) support and cost-effective access. The integration between optical networks and Worldwide Interoperability for Microwave Access (WiMAX) is a promising solution for future access networks. The integration between the Ethernet Passive Optical Network (EPON) and WiMAX has been proposed but contains several drawbacks and does not yet contain a mechanism for QoS support. Finally, this work describes the Resilient Packet Ring (RPR) standard, which aims to build high-performance metro that interconnect multiple access networks. The objective of this thesis is to examine the integration of optical standards, such as RPR and EPON, with the WiMAX standard as a promising solution for access and metro networks. The integration will be applied to the areas of architecture and Medium Access Control (MAC) Protocol. The first part of the thesis examines the EPON-WiMAX integration as a solution for the access network. Specifically, the proposed solution includes new EPONWiMAX hybrid network architectures that are suitable for both urban and rural environment requirements, and it also introduces a comprehensive joint MAC protocol for these architectures. The proposed architectures are reliable and provide extended network coverage. The proposed MAC protocol provides a per-stream quality-of-service guarantee and improves the network utilization. While the first part of the thesis strives to improve the network reliability through protection in the EPON part and extend the network coverage through innovative methods, the second part attempts to maintain and enhance these objectives by adding a reliable technology to the integrated network. Specifically, this section examines the way in which the RPR network can be integrated with the proposed EPON-WiMAX architecture to form an RPR-EPON-WiMAX hybrid network, which can be a solution for both access and metro networks. The proposed joint MAC protocol for the RPR-EPON-WiMAX hybrid network aims to maximize the advantages of the proposed architecture by distributing its functionalities over the parts of the architecture and jointly executing the parts of the MAC protocol.

"This wonderful book is the first one to address the rapidly emerging optical OFDM field. Written by two leading researchers in the field, the book is structured to comprehensively cover any optical OFDM aspect one could possibly think of, from the most fundamental to the most specialized. The book adopts a coherent line of presentation, while striking a thoughtful balance between the various topics, gradually developing the optical-physics and communication-theoretic concepts required for deep comprehension of the topic, eventually treating the multiple optical OFDM methods, variations and applications. In my view this book will remain relevant for many years to come, and will be increasingly accessed by graduate students, accomplished researchers as well as telecommunication engineers and managers keen to attain a perspective on the emerging role of OFDM in the evolution of photonic networks." -- Prof. Moshe Nazarathy, EE Dept., Technion, Israel Institute of Technology - The first book on optical OFDM by the leading pioneers in the field - The only book to cover error correction codes for optical OFDM - Applications of OFDM to free-space communications, optical access networks, and metro and log haul transports show optical OFDM can be implemented - An introduction to signal processing for optical communications - An introduction to optical communication fundamentals for the wireless engineer
