MARQUETTE, Mich. (AP) - Saying tomorrow's economy can't thrive on yesterday's infrastructure, President Barack Obama on Thursday promoted his five-year plan to lure new industries and jobs to the U.S. by expanding high-speed wireless to 98 percent of the country.

"It's just like that movie, 'Field of Dreams:' If we build it, they will come," he said in this snowy, Upper Michigan university town where many small businesses owe their success to high-speed Internet access.

 "For our families and businesses, high-speed wireless is the next train station, the next off-ramp, Obama said. "It's how we'll spark new innovation, new investments and new jobs," Obama said at Northern Michigan University, a wired campus where the students telecommute.

Obama's goal is lofty, considering that such technology is only now being built in major cities by AT&T, Verizon and others. It also will cost billions of dollars that Republicans are unlikely to want to spend.
