Data Networking is a capability that allows users to combine separate data bases, telecommunication systems, and specialised computer operations into a single integrated system, so that data communication can be handled as easily as voice messages. Data communications is the problem of getting information from one place to another reliably (secure both from channel disruptions and deliberate interference) while conforming to user requirements. IP (Internet protocol) is the central pillar of the Internet and was designed primarily for internetworking as being a simple protocol almost any network could carry. The business world appears to increasingly revolve around data communications and the Internet and all modern data networks are based around either the Internet or at least around IP (Internet Protocol)-based networks. However, many people still remain baffled by multiprotocol networks - how do all the protocols fit together? How do I build a network? What sort of problems should I expect? This volume is intended not only for network designers and practitioners, who for too long have been baffled by the complex jargon of data networks, but also for the newcomer - eager to put the plethora of "protocols" into context. After the initial boom the rate of IP development is now beginning to stabilise, making a standard textbook and reference book worthwhile with a longer shelf life. Highly illustrated and written in an accessible style this book is intended to provide a complete foundation textbook and reference of modern IP-based data networking - avoiding explanation of defunct principles that litter other books. Network/IP engineers, Network operators, engineering managers and senior undergraduate students will all find this invaluable.

Fixed wireless access networks and Wireless Local Loop (WLL) technology are effective and efficient means for rapidly creating new access to telecommunications networks and services which are short of capacity and incapable of handling the bitrates expected by today's high speed multimedia, Internet, video and voice services. Wireless Access Networks is a complete reference for all involved in fixed wireless access and wireless local loop, including business strategists, marketing, technical, planning and operations staff of public network operators, as well as students. Well-illustrated and simple-to-read, topics covered include: * Economics of fixed wireless networks - why and when they are attractive * Technical and operational planning, practicality and maintenance * Design of radio systems and their basic functionality * Point-to-point (PTP) and point-to-multipoint (PMP) radio * Calculation of radio system range and reliability * Fixed wireless applications and their network integration

Telecommunications network design and operation is now widely regarded as an issue of business management as well as electrical engineering. In this updated edition, Martin Clark, a pioneer of this perspective, applies it to the increasingly complex and diverse realm of voice, data and multimedia networks. Written in an accessible style and clearly illustrated throughout, this is a basic, practical and intuitive insight into modern network engineering with sections including: * Technical accounts of modern voice, data and multimedia networks * Coverage of ATM, B-ISDN, SDH, mobile radio and satellite networks, Internet and TCP/IP * Practical aspects of running and setting-up networks * Running a business based on telecommunications A text specifically for readers new to the whole subject of telecommunications, and professional telecommunications managers who need an introduction and reference work on all aspects of technology, operational techniques and regulation.

The modern telecommunications world is a complicated place, overloaded with jargon and bewilderingly full of different technical options and opportunities. Many experts are only experts of small domains and within limited geographies. For newcomers it is often difficult to gain a grasp on the basic principles and even harder to unravel the mysterious technical paradoxes and the apparent contradictions of many modern technologies. My greatest hope in writing this book is that you, the reader, will find help and insight amongst its pages. I wish for no greater commendation than your thoughts that you find the subject of A TM presented here in an accessible and readable form. I hope also that the comprehensive glossary will remain with you, as your wayfinder through all that jargon! Martin P.
