- Summary:
- The telecom industry faces nonstop change: new technologies, new business models, new competitive environments, and changing regulations. Now, one of the industry's most respected experts presents a systematic guide to the "New Telephony": where telecom has come from, where it stands now, and where it's headed. Telcordia principal and fellow Stephen M. Walters offers exceptional insight into today's telecommunications "battlefield," comparing the strengths, weaknesses, and business models of traditional and Internet-focused service providers. Walters identifies and thoroughly evaluates the key factors that will drive -- or prevent -- success in tomorrow's radically new telecom environment. Whether you're a telecom manager, buyer, consultant, investor, analyst, or technical professional, this book offers a comprehensive framework for making intelligent decisions -- for your company, your finances, and our future.
