AT&T on Monday confirmed expectations and said it would buy Qualcomm's FLO TV spectrum. The carrier will spend $1.93 billion to buy airwaves in the lower 700MHz range to bolster AT&T's 4G download speeds in key areas, 12MHz of which focuses on major cities such as Boston, Los Angeles, New York City, Philadelphia and San Francisco. Another 6MHz covers a wider swath of the US and about 230 million potential users.
