After spending almost a billion dollars to purchase 23 spectrum licenses in the 600 MHz bands, AT&T has filed an application to sell most of those licenses. The buyer is a Florida firm connected to Columbia Capital, a private equity group that backed one of the smaller companies that bid in the government’s recent 600 MHz auction.

In a late-December filing with the FCC, AT&T said it wants to sell 16 licenses in 11 cities to LB License Co., naming Monish Kundra as the principal contact at LB License. Kundra is a partner at Columbia Capital, where he specializes in spectrum investments. Prior to joining Columbia Capital, Kundra was Senior VP of corporate development for Mobile Satellite Ventures, better known as Lightsquared.

Columbia Capital financed Channel 51, one of the bidders in the FCC’s recent auction of 600 MHz spectrum. Channel 51 spent $859 million to acquire eight licenses. Now Columbia Capital appears ready to add to its holdings by purchasing most of AT&T’s licenses.

AT&T plans to sell spectrum in 11 markets: Dallas, Atlanta, St. Louis, Salt Lake City, San Francisco, Tampa, Columbus, Minneapolis-St. Paul, Seattle, Philadelphia, and Baltimore, MD-Washington, DC. In several markets, including Dallas and St. Louis, AT&T plans to sell several licenses, bringing the total number of proposed sales to 16.

In the government auction, AT&T spent $910 million to acquire 23 licenses in the 600 MHz band. The licenses covered 18 partial economic areas. Among the U.S. nationwide carriers, AT&T and T-Mobile US were the only purchasers of 600 MHz spectrum, and T-Mobile was by far the biggest buyer, spending almost $8 billion to acquire 1,525 licenses.

AT&T’s application to sell its licenses, which was spotted by Fierce Wireless, notes that LB License is “directly or indirectly controlled” by a corporation “of which more than one-fourth of the capital stock is owned of record or voted by aliens, their representatives, or by a foreign government or representative thereof, or by any corporation organized under the laws of a foreign country.” The filing does not name the foreign government.

The proposal to transfer spectrum comes as AT&T is preparing to add radios and antennas to its towers to support the 700 MHz spectrum it won as part of its contract to build a nationwide public safety network (FirstNet). The carrier had said it planned to add equipment for its new 600 MHz spectrum bands at the same time.

It’s possible that AT&T’s decision to sell spectrum is partially related to the challenges involved in trying to deploy both the 600 MHz spectrum and the 700 MHz spectrum at the same time. The 600 MHz spectrum was previously used by broadcasters, and before wireless carriers can use it those TV stations need to move their signals to other spectrum bands. This is expected to take at least two years for some broadcasters, and AT&T may not be willing to wait that long.
