Book Description
If you've been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire specification, then look no further. This comprehensive overview describes the underlying principles, implementation details and key enhancing features of 802.11n and 802.11ac. For many of these features the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40/80/160 MHz channels, transmit beamforming and packet aggregation) is given, plus clear summaries of issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughput, including revised chapters on MAC and interoperability, plus new chapters on 802.11ac PHY and multi-user MIMO. An ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communications.

Book Description
During the last thirty years or so it has been widely recognised in the research community that the key transmission medium seeming capable of serving both the ever-growing demand for bandwidth and the unceasing need for new services, is optical fibre. In this context, Wavelength Division Multiplexing (WDM) is the most popular technique for introducing concurrency among multiple user transmissions into the network and, thus, exploiting the huge amount of fibre bandwidth available under the severe limitations imposed by electronics speed on the maximum network access rate. This book extensively covers an important research area in optical networking, enabling readers to fully understand the concepts of optical LANs and learn details of architecture issues and control protocols. Through its careful focus on the local area, the book, covers the major architectural, topological and protocol issues regarding optical Local Area Networks (LANs) today. Considering that constant advances on optical component technology make all-optical WDM LANs all the more feasible for a wide commercial deployment, the book investigates thoroughly the crucial latter topic, i.e. the Media-Access Control (MAC) protocols that should be used. Besides introducing a noteworthy part of the vast literature on such protocols and providing some helpful distinguishing key protocol characteristics, the book is also innovative in focusing on a recent significant class of promising protocols whose operation is based on network feedback information. In this way, these adaptive protocols for optical LANs achieve an overall higher performance in comparison with many other non-adaptive schemes. Multiwavelength Optical LANs: Enables readers to understand the concepts of optical LANs and learn details of architecture issues and control protocols Focuses on the major architectural, topological and protocol issues regarding optical local area networks Presents the important class of adaptive protocols for optical LANs No Optical systems/network developers, or engineers and scientists working in optical networking should be without this book. The well considered approach also makes this recommended reading for undergraduate and graduate computer science, computer, electrical and telecommunications engineering students.

Book Description
Open System LANs and Their Global Interconnection focuses on the OSI layer 1 to 4 standards (the OSI bearer service) and also introduces TCP/IP and some of the proprietary PC Local Area Network (LAN) standards. The publication first provides an introduction to Local Area Networks (LANs) and Wide Area Networks (WANs), Open Systems Interconnection (OSI), and LAN standards. Discussions focus on MAC bridging, token bus, slotted ring, MAC constraints and design considerations, OSI functional standards, OSI model, value of the transport model, benefits and origins of OSI, and significance of the transport. The manuscript then takes a look at Data Link Control Standards and Network Layer Control. Topics cover relaying, addressing, and routeing, use of the ISO 8473 Network Protocol in LANs, Connectionless-mode Network Protocol ISO 8473, connection-mode and connectionless-mode, High Level Data Link Control (HDLC), and data link control in WANs and LANs. The text examines structured building cabling, OSI management, functional standards and proprietary competitors, and transport control standards. Concerns include Connection-mode Transport Protocol, Network Connection Management Subprotocol (NCMS), OSI functional standards, management information model, LAN management, Simple Network Management Protocol (SNMP), and supporting LAN Standards. The publication is a vital reference for computer science experts and researchers interested in open system Local Area Networks.

Book Description
The content of this book is the result of the work and the experiences of an interdisciplinary and strictly European group of researchers who have attempted to give birth to a new fibre communication network concept by exploiting the potential benefits of optical coherent transmission. The run towards this ambitious goal started in 1985 on the basis of the ESPRIT program incentives by an "ad hoc" consortium of industrial partners and research institutions. The first three years were dedicated to a feasibility study carried out by a reduced number of "pioneers". In 1989 the team was extended to eleven partners. There was already clear evidence of the increasing interest in Europe in exploring the actual limits of optical fibre coherent systems; the project had innovative and very advanced features that were gradually refined by incorporating the latest technological developments to which it has directly contributed. The main objective of the project targeted the development of the necessary building blocks to show experimentally the performance and the flexibility built into the proposed concept of multi-channel ultra-wideband network. The system concept developed within this project associates optical frequency division multiplexing with a suitable network architecture and management techniques to allow very high flexibility and efficiency in handling simultaneous transmission over the network (on each optical frequency) of multiple virtual channels each operating with a wide range of information rates ranging from a fraction of a Mb/s up to a maximum value in excess of 160 Mb/s.
