UPDATE 1-D. Telekom CEO says T-Mobile USA sale is on track

COLOGNE, Germany, May 12 (Reuters) - Deutsche Telekom DTEGn.DE CEO Rene Obermann said he was confident that the sale of the group's U.S. operations would be completed next year.

U.S. carrier AT&T T.N agreed to buy T-Mobile USA in March for $39 billion but the transaction needs antitrust clearance.

Obermann told shareholders at the company’s annual general meeting in Cologne on Thursday that he expected the deal to close in the first half of next year.

Deutsche Telekom sold the struggling business to focus on Germany, its largest market, and its other European operations.

The company aims to eventually compensate a decline in its traditional business with new revenue streams from services around mobile devices and the Internet.

Obermann said the potential of the mobile Internet was just beginning to show, adding that with mobile internet services the company could generate billions of euros even without the U.S. business.

In addition, he said, Deutsche Telekom was working on rolling out fibre to homes and aimed to reach 10 percent of all German households in the coming years. Last year however, it had said it aimed to reach 10 percent by the end of 2012. (Reporting by Peter Maushagen and Nicola Leske)
