Mobile Wireless technologies are currently moving from circuit-based first-generation and 2G systems to packet-oriented 2.5 and 3G systems. We will discuss how the infrastructure and mobile devices will make the transition, while focusing on internet access for mobile services and opportunities for IP core service providers in 2.5 and 3G networks.
