Real-world instruction in the design and deployment of 3G networks Pin down the technical details that make 3G wireless networking actually work. In 3G Wireless Networks, experts Clint Smith and Daniel Collins dissect critical issues of compatibility, internetworking, and voice/data convergence, providing you with in-depth explanations of how key standards and protocols intersect and interconnect. This guide digs into the gritty details of day-to-day network operations, giving you a chance to understand the difficulties service providers will experience in making the changeover from 2nd Generation systems (CDMS etc.) to 2.5 Generation systems like WAP and EDGE and finally to full throttle 3G networks. It describes key standards, digs deep into the guts of relevant network protocols, and details the full range of compatibility issues between the US (CDMA 2000) and European (WCDMA) versions of the standard. Plenty of call flow diagrams show you exactly how the technologies work.

AN UNCONVENTIONAL, FUN WAY TO MASTER THE BASICS OF CRYPTOGRAPHY Cryptography is not just for specialists. Now every wireless message, wireless phone call, online transaction, and email is encrypted at one end and decrypted at the other. “Crypto” is part of the job description for network designers, network engineers, and telecom developers. If you need cryptography basics—but dread the thick tomes that are your only other option—help is at hand. Cryptography Demystified puts the fundamentals into a 35-module, learn-by-doing package that’s actually fun to use. You must read this book if— * You prefer your simplifications from an expert who understands the complexities * 6 years of success as a short course for students and professionals works for you * you enjoy hearing the phrase “nothing to memorize” * ecommerce, email, network security, or wireless communications is part of your bailiwick * cracking cryptography means a jump up the career ladder * the words “public-key cryptography,” “channel-based cryptography,” and “prime numbers” pique your interest * best-practices cryptography is the only secure way for you—and your company—to go One of the most complex subjects in Information Technology, cryptography gets its due in this down-to-earth, self-teaching tutorial—the first to make the basics of the science truly accessible.

Within the next few years, 40% - 50% of all companies will attempt to execute a wireless application strategy--bringing the number of wireless data users to a whopping 36 million by 2003! Wireless LANs are now considered the best bet for wirelessly enabling business since the technology can be quickly and inexpensively deployed using existing infrastructure. * Shows how to wirelessly enable employees to work from any location within the office, as well as home and outside locations * Discusses the different wireless protocols and standardes: 802.11, Bluetooth, WAP, CDMA, 3G, etc. * Covers all the benefits of wireless LANs, with specific cost reductions and support solutions * Includes "insider" information about deploying Microsoft .NET-related wireless LAN applications.

Everything telecom professionals need to know about using SMS on mobile devices, and the incredible financial possibilities of doing so.

This handbook is designed to demystify IP telephony for business people and technology generalists. It discusses: IP protocol breakdown -SIP, H.323, Megaco/H.248; quality of service - IntServ, DiffServ, and MPLS; integrating voice into a LAN data environment; and cost and service implications.

As wireless networks take ever-bigger bites out of the USD 350 billion dollar telephone market, they create their own performance problems. International customers require global networks; more customers mean bigger networks; new services create more complicated networks. Then there's changing out the network; each time a provider introduces a new technology or capability, it has to do so without interrupting service delivery to existing customers. Here is realistic advice on metrics, troubleshooting methods, design guidelines, revenue assurance and more, from a team that has performed the same services for AT&T Wireless, Nextel and Verizon.
