1920's radio policy debate
• Fundamental tension: press freedom vs scarce spectrum
• Alternatives debated?• Relative merits?• Market for spectrum–Why not initially?– Primary vs secondary market

Spectrum and licenses• Channels: artificial structure on ethereal resource
AM radio: 10 kHz / channelFM radio: 200 kHz / channelTV: 6 MHz / channel
• Spectrum scarcity leads to government allocation of licenses• Who gets licenses? Typically powerful players
- existing radio stations received TV licenses- existing TV station receive HDTV spectrum- after initial allocation, secondary market
• License renewals: over 10,000 in the US since 1950s, only 50 contested, only 20 denied.
• Alternatives:- spectrum auctions (primary market)- unlicensed spectrum
• Trends: redefined basis for spectrum property rights

Spectrum policy trends
• Reallocation of spectrum from Federal government use to non-Federal government use
• Allocation of more spectrum for mobile as opposed to fixed applications
• Use of auctions to assign spectrum to particular users (started 94)
• Increased licensee flexibility in the use of assigned spectrum
• Continued support for unlicensed services• Increased competition in the provision of all
telecommunications services, including radio-based services
• Increased reliance on voluntary standards.
