Wireless Phone Technology

Currently, cellular phones in the United States have a data transfer rate of 115 kilobits per second. The next generation of cellular phonesùso-called 3G phonesùare set to deliver rates of 2 megabits per secondùa significant improvement. While not as critical to those who use their phones only for voice messages, 3G data transfer rates promise considerable benefit to those who use their phones for increasingly sophisticated applications such as surfing the Web, sending and receiving text messages, and accessing e-mail (Aquino, 2004).

3G was originally designed to provide a single worldwide standard for cellular phones; in practice, three standards have emerged: W-CDMAùalso called UMTS, CDMA2000 and TD-SCDMA. The first two are spread rather evenly throughout the world, with WDCMA having a strong presence in Europe, and CDMA2000 popular in the Americas and Asia. China is the only large market deploying TD-SCDMA. As of April 2004, deployment of 3G networks was not consistent, with Germany and the United Arab Emirates using W-CDMA, but with France and the United Kingdom still lacking a 3G network. At the same time, Argentina had deployed a CDMA2000 network, as had Canada, but the USA still lacked a 3G network. Such a network is currently expected in 2005 ("3G," 2004).

Despite its initial promise, and although 3G will enhance data transmission rates, it will not result in a single worldwide standard.
