"Carriers already have razor-thin margins after spending billions of dollars building out their 3G networks"
I read this earlier today and my BS meter went off
Then by the end of 2013 we're going to have our entire current 3G footprint covered by 4G. So in other words, everywhere we have 3G coverage today we'll have 4G coverage. And we'll also have places where we don't have 3G coverage today that we'll have 4G.
The big thing for us is that 100% of the 700MHz spectrum we won in the FCC auction a couple years back will be used for 4G services.
