Early on, C.D.M.A. promised to carry 27 digital conversations for every analog conversation, but technical obstacles have reduced that ratio to something like 10 to 1 today. By comparison, T.D.M.A. carries about 7 calls for every analog conversation. Rather than adopt T.D.M.A. or C.D.M.A. as a national digital standard, however, the federal government allowed manufacturers and carriers to choose between the systems. That is the main reason that a phone bought from AT&T, for example, won't work on the Sprint PCS network. AT&T and Cingular use T.D.M.A., and Sprint PCS and Verizon use C.D.M.A. The adoption of one standard in Europe — G.S.M., an advanced version of the digital technology available in the United States — has helped spur the relatively smooth expansion of the cellphone industry there, said Roberta Wiggins, director of wireless mobile services at the Yankee Group, a consulting firm. G.S.M. has been adopted by a few wireless companies in the United States, notably VoiceStream, and AT&T and Cingular are planning such a shift as well. "Europe had the advantage because they basically had one standard," Ms. Wiggins said. "As a result, they're further along in technology and coverage."nytimes.com nytimes.com February 14, 2002 Talking More but Enjoying It Less By JEFFREY SELINGO "...The wireless operators certainly present an image of ubiquitous coverage in their advertising campaigns," said Philip Marshall, a senior analyst at the Yankee Group, a market research firm. "But the days are gone when subscribers were more accepting of poor network performance. They have increased expectations because they're more reliant on the phones." Beth Case, a sign-language interpreter in Fresno, Calif., grew so frustrated with her Cingular phone service at one point last year that she stopped her car at a pay phone when she needed directions to a client's home. "It totally defeated the purpose of having a cellphone," she said. Of the 100 calls on her bill one month, she said, fewer than 20 of them lasted for more than two minutes because calls were continually dropped. Ms. Case switched to Sprint PCS in November and said she had had no problems so far." nytimes.com - Fred
