Sprint Corp. (S) is joining forces with its former takeover suitor, Dish Network Corp., to test a wireless Internet service.

The companies will begin offering high-speed broadband in Corpus Christi, Texas, in the middle of next year, with plans to expand to other markets, they said today in a statement. The service would only cover a customer’s home or business, competing with landline Internet providers such as AT&T Inc. and Comcast Corp.

The project signals a thawing in relations after Dish tried unsuccessfully, and without the support of Sprint’s executives, to outbid SoftBank Corp. for control of the third-largest U.S. mobile-phone company. Dish, the country’s second-biggest satellite-TV provider, has been amassing its own airwaves to branch out into wireless service.

“This trial with Dish has great potential as it combines the key capabilities and assets of both companies to provide another option to customers with limited broadband access,” Michael Schwartz, Sprint’s senior vice president of corporate and business development, said in the statement.
