I thought the point was that this is UNLICENSED spectrum. I can't legally set up a WiMax tower like I can set up a WiFi hot spot. Doesn't opening whitespaces mean that you could set up, say, a city-wide access point without asking permission? Or did I miss something? If that's the case, it's likely to spawn LOTS more competition than assigning frequencies to the highest bidder - which is actually 0 competetion, actually; it's a granted monopoly. If I'm understanding right, there could be networks that are not for profit, or indirectly so. Like, maybe a hospital could have a Wi-Fi-like network that spans the whole city, which their ambulances could use to transmit vitals to the hospital while bringing in a patient.
