There was not restriction of technology for that band. I think the problem is that there is no business case at the moment. There is no technology defined for that band, nor terminals. To get this band implies to choose the technology (HSPA, CDMA EV-DV, LTE, etc) in that frequency and develop it together with the terminals for that band. This would be a very risky business, even more than that of Sprint trying to offer WiMAX as a "4G" technology (makes no sense...)
