Scalable VoIP Mobility

Book Description

Today's businesses, big and small, are faced with the large scale restructuring concerning daily communications. Enterprises are moving from the standard wired telephony to wired and wireless communication via internet protocol (IP), Wi-Fi, and cellular services. With the stabilization of these networks and the availability of dual-mode handsets multimodal voice mobility networks are becoming low cost and highly effective.

This book provides practical advice on breaking down implementation and deployment. Scalable voice mobility solutions are analyzed and optimized dependent upon available budget and infrastructure options. The ultimate choice for an installation could incorporate a variety of networks. The author touches upon 3G+ cellular networks, CDMA 2000, WCDMA, HSPA, and WiMAX radio networks, and high-level networks including IMS. Security, fixed-mobile convergence, and emergency services are also considered in this guide for network designers, managers, and architects.

*Voice mobility clearly defined with an emphasis on implementation across platforms
*In-depth discussion of all wireless technologies including voice over ethernet, Wi-Fi, cellular and licensed spectrum
*Fixed-mobile convergence deployment tactics explained
