Samsung Electronics Co. and Sprint Nextel Corp. are joining forces to bring fourth-generation high speed wireless Internet to New York City.

Samsung said in a statement Monday it was selected by Sprint Nextel to provide infrastructure for New York, part of the Reston, Virginia-based wireless provider's plan to launch the network in several U.S. cities based on an emerging mobile wireless technology called WiMax.

Samsung had already been chosen by Sprint Nextel to provide infrastructure and equipment for similar networks planned for Baltimore, Boston, Washington, D.C. and other cities. Financial terms were not disclosed.

"New York is an important milestone for Samsung as we continue to expand the deployment of (WiMax) technology around the world," Choi Gee-sung, president of Samsung's telecommunication network business, said in the statement.

Sprint will "go for a commercial launch of our service starting in Washington in April of next year," said Barry West, president of the company's WiMax business.

He added that service in other cities would follow "with New York probably in the fourth quarter of next year."

Sprint Nextel said two weeks ago it would spend 5 billion U.S. dollars through 2010 on the WiMax network, to be sold under the brand Xohm. It also said it expects the network, which promises fast wireless broadband connections and mobile roaming at high speeds, to generate between 2 billion dollars and 2.5 billion dollars in revenue by that time.

The costs could have been higher, but Sprint Nextel last month said it would team up with competing provider Clearwire Corp. to help build the WiMax network, reducing the company's outlay by up to 70 percent.
