Wireless broadband network company LightSquared has won a deal to help Best Buy Co Inc instead of looking to LightSquared to expand its access to wireless airwaves.

LightSquared executives said they had not given up on signing up T-Mobile USA as a customer even though the carriers have said the main reason for the merger was access to more airwaves.

If they needed spectrum before, they'll still need it after (the deal), said Ahuja. They're potential customers afterwards.

AT&T, however, would be restricted to no more than 25 percent of LightSquared spectrum because of U.S. government regulations.

Chief Marketing officer Frank Boulben said LightSquared has already signed a deal with a maker of tablet computers and smartphones that could start using LightSquared's network as soon as the fourth quarter. He said the customer did not want to be named for competitive reasons.

LightSquared is also in advanced talks with one of the top three global consumer electronics companies about providing connections for services such as wireless photo uploads and wireless multiplayer gaming, Boulben said.

We're in negotiations for 15 contracts, he said.

Ahuja said LightSquared and Best Buy would start a trial of the retailers wireless service in early 2012.

Best Buy already has a deal to buy wireless services from No. 3 U.S. mobile service Sprint Nextel Corp and Clearwire Corp in which Sprint has a 54 percent stake.

Ahuja said Best Buy could offer services from different networks on different devices or it could combine the technologies on some devices.

Several analysts had hoped Ahuja would announce a network agreement with Sprint at the CTIA. It could share Sprint's wireless towers and possibly its network equipment with a view to cutting costs, they said.

Such a deal could be completed as soon as late March, according to a source familiar with the talks between Sprint and LightSquared. Ahuja declined to acknowledge or comment on the talks.

The executive said during his keynote speech that there is room for a company such as LightSquared, even in the fiercely competitive U.S. mobile market, because it takes a new approach and will not compete with its service provider clients.

It opens up the wireless industry to new entrants who could never before offer wireless service, Ahuja said referring to Best Buy as an example.
