Radio astronomy receiver overview
... In principle, we could measure the power from a radio source by measuring
how much it raises the temperature of an energy absorber tied to the antenna.
However, radio sources are much too weak to do this directly. We need to
amplify the radio source signal enough to drive a power detector. This adds ...

A spectrum auction is a process whereby a government uses an auction system to sell the rights (licences) to transmit signals over specific bands of the electromagnetic spectrum and to assign scarce spectrum resources. Depending on the specific auction format used, a spectrum auction can last from a single day to several months from the opening bid to the final winning bid. With a well-designed auction, resources are allocated efficiently to the parties that value them the most, the government securing revenue in the process. Spectrum auctions are a step toward market-based spectrum management and privatization of public airwaves, and are a way for governments to allocate scarce resources.Alternatives to auctions include administrative licensing, such as the comparative hearings conducted historically (sometimes referred to as ""beauty contests""), or lotteries.
