Spectrum Policy.

The Economist writes that "governments and industries are bracing themselves for the possibility that radio interference will become a thing of the past."


On one side, therefore, are notions of radio frequencies as scarce resources that can be used by only one transmitter at a time and are worth lobbying and paying billions for; on the other side is the idea that any number of transmitters and receivers can peacefully co-exist on the airwaves and that spectrum should therefore be open to allónot individual property, but rather a commons. To understand this debate, one must look back at history; to understand its importance, at economics.

The article discusses four technologies:
- spread spectrum or wideband
- smart antennae
- mesh networking
- cognitive radios
