About one-third of Internet users in the U.S. have used a wireless connection to surf the Web or check e-mail, according to a survey released Sunday.
The survey by the Pew Internet & American Life Project showed that 34 percent of Internet users have gone online through Wi-Fi service or a cell phone network, including 27 percent who have logged on from somewhere other than their home or workplace.
That's up from February 2004, when 22 percent of Internet users said they had gone online using a wireless device.
Nineteen percent of Internet users now have a wireless network in their home. That number has nearly doubled since January 2005, when 10 percent said they had a home wireless network.
Three-quarters of the people with both a home wireless network and a laptop computer said they now use their laptop in different parts of the house.
One in four Internet users said they have a cell phone that can access the Internet, and 54 percent of those with the capability said they have used it to get online.
About 13 percent of Internet users have a personal digital assistant, and 56 percent said they have used it to access the Internet or e-mail away from home or work.
The telephone survey of 798 Internet users was conducted from Nov. 30 to Dec. 30. It has a sampling error margin of plus or minus 4 percentage points.
