【摘要】
    America’s race to achieve 3rd generation (3G) wireless capabilities will redefine the way telecommunications companies operate, and determine how Americans communicate with one another. Wireless communication is slowly moving away from the world of limited bandwidth 2nd generation (2G) wireless technology to the next generation of wireless infrastructure that enables significantly higher bandwidth. This higher bandwidth will lead to the convergence of devices. Consumers will begin to utilize devices that combine cell phones, PDAs, video cameras, pagers, and other various gadgets. Increases in bandwidth will also enable users to download rich multimedia and access up-to-the-minute data from the Internet.3G is a global wireless communication technology that makes packet-based transmission of digitized voice, data, and video a possibility. Packet-based networks provide an “always on” capability, which is not available through circuit based 2G networks. This evolution in technology also makes networks more bandwidth efficient and lowers carrier’s costs. With the emergence of 3G the traditional billing model of charging by airtime no longer applies. The “always on” concept of packet-switching means that charging for long distance and the duration of a call are not appropriate, because they don’t accurately reflect the amount of resources being used. New pricing models will likely be based on a combination of the amount of data transmission and charges for various services and content. The bill received from a 3G service provider will likely resemble a credit card statement rather than a typical telephone bill. Third party applications and services, such as a subscription to a wireless based MP3 download site,will be billed through the service provider.
