Under the heading “What Next” we have this: “Offering his outlook for the age beyond 3G, Siemens’ Pauly says: “The Internet Protocol is taking on tremendous significance as the central protocol, both for voice and data transfer in fixed and mobile networks as well as for the development of convergent applications for all networks…Central to the development is IMS (IP-based Multimedia Subsystem), a standardised platform that can quickly and cost-effectively provision a wealth of IP-based applications. Push-to-talk, the walkie-talkie functionality for mobile handsets, runs on IMS, for example.” The article goes on to (mis?)quote someone saying there are 120 billion 3G subscriptions, which would be 20 each for every person on the planet.
