ommunications ANNABEL Z. DODD PRAISE FOR THE ESSENTIAL GUIDE TO TELECOMMUNICATIONS, FIFTH EDITION "Dodd's The Essential Guide to Telecommunications provides the history and context that make a fun- damental underpinning of modern business more accessible to technologists and businesspeople alike. This new edition of her primer is an essential reference in the continuously evolving communications landscape." -Tom Hopcroft, President and CEO, Mass Technology Leadership Council "Annabel Dodd's book is a clear guide and big-picture view of technologies and industries. It is an up-to- date guide for anyone who wants to be familiar with important innovations and key technologies. This is truly an industry bible for mobile, Internet, and networking services." -Hiawatha Bray, Technology Reporter, The Boston Globe "Annabel Dodd has created a mainstay resource in The Essential Guide to Telecommunications. All edi- tions have been written in such a way that nonengineers and engineers alike will benefit from reading. She does the BEST job that I have seen in assimilating all of the changes that are constantly occurring in the telecommunications industry, both technical and regulatory, into one text. When I walk through telecommunications offices, I always see various editions of her book on multiple shelves. If you want one book that provides a concise and encompassing view of telecommunications, THIS is it!" -Ronny Puckett, Southwest Region Director, National Exchange Carrier Association "I have used previous editions of The Essential Guide to Telecommunications for some time in my introductory courses in our Information and Telecommunications Systems degree program. As this is a stand-alone IT degree program, we need a textbook with broad coverage of technical, management, and regulatory/policy topics. The Essential Guide to Telecommunications provides that coverage in an accessible and accurate manner. It is one of a very small number of books that I have been comfortable using as a required text in my courses." -Hans Kru
