Unity Eludes 3G Mobile Phone Standards

摘要

The large annual growth of mobile-phone usage is greatly changing the way we live. Congregating in Times Square to see the ball drop at midnight on New Year's eve may no longer happen. Some industry watchers predict that instead families will be informed of the new year's arrival with nanosecond precision by colorful and intriguingly shaped personal information appliances. According to Ken Woo, director of corporate communications at AT&T Wireless Services, about 5 million of the world's 16 million CDMA IS-95 phones are being used in the United States. Half of the 9 million AT&T Wireless customers use IS-136 TDMA phones and half continue with ana- log phones. They are not alone. Approximately 100 million wireless analog 1G phones still are in use worldwide.
