First, let it be said that I am not an expert on these matters, nor did I RTFA.
However, that being said, It definitely appears that the high cost of entry into this market is the source for most of the industry's issues. It leads to less competition and a sort of oligarchical group think by the participating bodies (usually corporations). To me, this seems obvious. If it costs an astronomical sum to enter into a market, it seems only natural that the only people (corporations) in the market would be the ones that can be relatively sure that they can extract large sums of money from the market. The inevitable consequence of this is business model entitled "How can I screw the customer the most and still get away with it?"
Perhaps I'm not well informed enough, but it would seem to me that the real solutions for "high cost" markets is government ownership of infrastructure (like sewers and roads), or at least a mandate for non-reproduction of distribution (like power lines or water lines). It is true that government usually finds the least efficient method of doing anything, I will not dispute that. However, we can all agree that have three or four sets of sewers, roads, power lines, and/or water lines would be even more stupid than current government management of these items.
The point is that the real cost of entry into this market is the creation of cell phone towers and other associated infrastructure. Granted, the big boys may have contracts that allow them to share resources, but I would bet dollars to donuts that they make a point of mutually excluding start ups from these contracts in order to prevent competition that doesn't agree with their business model (see above).
In short, the government is full of idiots, and the free market is full of idiots, because we are a nation composed mostly of idiots. Lacking a Philosopher King capable of determining Merit (with a capital M), we should probably just bet on pitting the government idiots against the free market idiots and hope that they beat the stupid out of each other until something usable is made. Leaving one or the other to their own devices is the worst thing we could do.
