　　The survey showed that 22 percent of EU households use only mobile phones，up from 18 percent a year ago，while the percentage of households with at least one fixed line decreased by 5 percent to 72 percent，although the percentage of households with at least one mobile phone remains fairly stable at 81 per cent.

　　Broadband is presenting a rapid upward trend in the EU，showed the survey，which polled(对……进行民意调查) 27,000 households across the union.Twenty­eight percent of households are now connected to the Internet via high­speed “broadband” links，up six percent from last year，while narrowband usage has dipped by three percentage points to 12 percent.More than half of households access the Internet via an ADSL line and 34 percent of broadband connections are wireless.
