Convergence Technologies for 3G Networks.IP, UMTS, EGPRS and ATM

Аннотация

The telecommunications industry, and particularly the cellular industry, is currently going through a state of enormous transition. Many of the major cellular operators are now deploying a network to support packet switched data services and lead them to third generation (3G). This step to 3G involves a major change in the network infrastructure with the introduction of complex technologies such as asynchronous transfer mode (ATM), code division multiple access (CDMA) and the Internet protocol (IP). For forward-looking operators, this transition also requires a clear, strategic transformation of their business model to grasp and maximize on the benefits of the next generation’s lucrative revenue streams.
