Clearwire Corp. said Monday it will sell its wireless broadband services under the brand name Clear, eventually replacing the Xohm brand that partner Sprint Nextel Corp. has used since September.

The Kirkland, Wash.-based company completed its merger with Sprint’s WiMax network Friday. Similar to the WiFi signals available at coffee shops and airports, WiMax technology can cover an entire city and offer faster data speeds than most current cellular broadband networks.

Sprint began offering WiMax service in Baltimore in September but hasn’t disclosed how many customers have signed up. Clearwire plans to begin selling WiMax in Portland, Ore., in the first quarter of 2009 and already has about 400,000 customers on a pre-WiMax network in 46 cities.

Chief Executive Officer Ben Wolff, making his first public announcements since the merger, told analysts and reporters during a conference call that the company will focus on upgrading that system to WiMax next year, as well as opening commercial service in several other cities.

Overland Park, Kan.-based Sprint will own 51 percent of the company, while investors in the original Clearwire, founded by cellular pioneer Craig McCaw, will own about 22 percent.
