Clearwire: Usage on our network increased 705% year-over-year

Clearwire customers apparently have an insatiable appetite for mobile data -- the company's network usage increased 705 percent year-over-year in 2011. According to Clearwire CFO Hope Cochran, some of that increase came from Clearwire adding new customers to its network, but she attributed most of it to the fact that existing subscribers are using more data every month. "Customers are finding more applications and downloading more videos," she said.
