Even as 3G is spreading the use, service providers are deploying wireless 4G (fourth generation) technology, which is expected to provide a speed five times or better than currently available.

Based in Kansas, Sprint Nextel, with an estimated 49 million customers, has launched a 4G in many cities, but none in Wisconsin.

New Jersey, Verizon Wireless, with about 88 million customers, is testing 4G in Boston and Seattle. Verizon plans to launch in 25 of its top 50 markets next year.

"The speed will be strong to the level of speed DSL home users we see today," said Vinge.

Bob Sobieck, technical director of Cellcom Green Bay-based, serving Upper Michigan and north-central and northeastern Wisconsin, said its 3G service is available in the industry since 2007. The company is in no hurry to move to 4G.

"For us, 4G will not arrive in 2010," he said. "But we are all waiting because there 4G devices on the market yet."

The best mobile companies use different technologies for 4G services.

Sprint is using WiMAX, which uses microwave signals. AT & T and Verizon are going with LTE or Long Term Evolution, which uses radio signals.

Vinge says Sprint is the majority owner of Clearwire, a company focused on the deployment of Sprint’s 4G service.
