Digital Regulator - Regulations on-the-fly
Wireless spectrum, although invisible to the naked eyes, is a huge asset to any country. Spectrum regulators all over the world contributed huge income to the nation through spectrum auctions. For example, Germany raised over EUR 50 billion through their 3G auctions back in 2000. The auctioned spectrum typically last for a certain period stipulated by the respective regulator, e.g., 20 years, after which the regulator has the right to retrieve the spectrum for other purposes.
