My understanding is that it only uses as much spectrum as you want the end user to have access to. So if you want each end-user to have 10 mhz then you only deploy 10 mhz. Now backhaul is a big beast with this, but if I am understanding his claims correctly, sprint could basically get away with using almost none of their spectrum and still have more end user bandwidth than they have now. I will definitely be following this.
