The electromagnetic spectrum allocated for mobile telecommunications is a scarce economic resource. A fundamental consequence of this scarcity is that:
it must be classified as a pure public good because electromagnetic waves propagate freely through open space.
its allocation to a specific telecommunications network always involves an opportunity cost.
it can only be allocated efficiently through an unregulated, free-market price mechanism.
it will inevitably be depleted to zero utility over time as a consequence of the law of diminishing returns.
