Dish has a seemingly insatiable appetite for wireless spectrum, and it's willing to spend a lot of cash to get its fill. Need proof? The FCC has just confirmed (PDF) that Dish bought all of the 1,900MHz licenses in a frequency auction that wrapped up last week, using a shell company to hide its name. The satellite provider paid just short of $1.6 billion for the airwaves -- chump change next to the spending on 700MHz blocks, but a large amount for spectrum where there wasn't much competition. While Dish isn't saying just what it will do with all that extra bandwidth, it's reasonable to believe that the company will use the newly acquired frequencies to boost its wireless broadband efforts.
