NTT DoCoMo holds a 16 percent stake in AT&T Wireless, which has pledged to bring high-speed third-generation, or "3G," mobile phone technology to San Francisco, Seattle, Dallas and San Diego by Dec. 31, 2004. To help get the ball rolling in the United States, the Japanese company is showing mobile phones with features that can take advantage of 3G wireless.
"We want the American consumer to understand what 3G is," NTT DoCoMo spokeswoman Karen Lurker said.
NTT DoCoMo showed its 2102 series, which is comprised of one handset that's available in Asia now and two more that were announced on Monday. The cell phones--produced by a variety of manufacturers--feature not just a built-in digital camera, but also a videocamera. With one, teenagers could send video to parents in order to prove that they really are where they say they are. The newer models come with authentication.
AT&T Wireless will use the same services and 3G network as does NTT DoCoMo, Lurker said. The network uses technology that's based on wideband code-division multiple access (W-CDMA), an emerging cellular standard that triples network capacity without requiring an upgrade by carriers. The network standard is also known as the Universal Mobile Telecommunications System (UMTS).
"We're hoping it gets adopted by as many carriers as possible," which would lower equipment costs and make it easier for people to roam from one country to another, Lurker said.
