The FCC released 20 Mhz of spectrum that can be used for 3G and other wireless services: The spectrum comes in 5 Mhz-wide swaths, which means it is suitable only for certain applications such as 3G or Flarion's Flash-OFDM technology. IPWireless and vendors of WiMax gear, however, require wider swaths of spectrum so in their current forms at least they wouldn't be possibilities here.
I shudder to think of the process of distributing this spectrum. This is prime real estate that lots of people would like to get their hands on.
