at some point the markets can become saturated, but i do not think that is the case with broadbent. if you have a robust competitive marketplace, it obviates the need for regulation on so many different levels. if you have one player acting in an anti-competitive way, from the consumer's perspective, then presumably consumers would have more choices. there has been discussion of spectrum audits. that would be a great idea, as long as we understand manager expectations ahead of time. it is difficult to pinpoint a point on the map at a point in time and determine who exactly was using that spectrum, and for what purpose. we have to manage those expectations, and there is a lot of talk on capitol hill about this. it will raise as many questions as it answers. government uses about one-third of all available spectrum. spectrum is finite. we are talking about the airwaves, the radio waves, and different frequencies are better for different purposes. some frequencies'signals can travel long distances and penetrate buildings, like television stations. others are better for medical devices
