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.

Master's Thesis from the year 2016 in the subject Computer Science - Miscellaneous, grade: 1,0, University of Applied Sciences Technikum Vienna (Telecommunications and Internet Technologies), language: English, abstract: Operator-provided voice services will gradually migrate from today's circuit-switched (CS) voice networks to packet-switched IP networks, using Voice over LTE (VoLTE) as the foundation to provide telecom-grade telephony services. In fact, the capability of transporting Voice over IP (VoIP) services along with the provision of high-rate data throughputs, characterizes one of the critical drivers for the LTE development. This thesis presents the first implications of introducing IMS-based VoLTE in Germany, Austria and Switzerland (DACH) from a mobile operator's perspective. Further VoLTE performance aspects such as parameter optimization and HD voice are discussed, thus serving as a basis to then analyze the DACH mobile network test results for 2014 in terms of telephony and data performance. Overall results for a DACH VoLTE trial conducted in the third quarter 2014 complement the analysis.
