Verizon's LTE network was already pretty speedy, and now the company has rolled out XLTE in 250 cities in 44 states, which delivers faster peak data speeds and a minimum of double the bandwidth. Wow, this is what I like to hear.

So how is it possible for them to make this jump? Last year the FCC approved Verizon's purchase of Advanced Wireless Service (AWS) spectrum, which has now been activated.
