I get how download will simply be broadcast like tv channels are now but now you will need your tv/laptop etc. to also broadcast. I would imagine it would be done like WiMAX but at what frequencies. Is the spectrum divided up into upload and download frequencies? What about the issue of antennas and circuitry. 700Mhz means your going to need bigger antennas and bigger components for efficient transmission so that kind of makes it hard to make small cell phone like devices.
