AT&Tはなにをしているのか?

AT&T, in fact, is still in the process of expanding its 3G network in the U.S. to the 350 cities it's promised to serve by the end of the year. Last month, when it released its second-quarter earnings, AT&T said that it had 3G service in about 300 U.S. metropolitan areas. At the time, the company claimed it was beginning work on boosting 3G capacity. "AT&T also has started doubling the data capacity of its 3G markets, and nearly half of all cell sites will receive additional 3G capacity by the end of the year," AT&T said in a July statement.
