6. Repackaging Options
• TV spectrum close in frequency
bands to mobile spectrum.
• Broadcast TV required substantial
interference bands (“guard
bands”).
• Digital TV needs less, though TV
broadcasters have increased
utilization.
• Options
• Reassign bands for single-use
• Open common white-space for use
subject to interference rules
• Partial clearing
• Partial clearing with re-packing Vidya Muthukumar, Angel Daruna, Vijay Kamble, Kate Harrison, and Anant Sahai,
“Whitespaces after the USA’s TV incentive auction: a spectrum reallocation case study,”
Wireless Foundations, EECS, UC Berkeley.

10. Auction Design – Broadcasters (Reverse)
• Starting prices
• Bid to relinquish license (go off-
air);
• Bid to relinquish current channel
in order to share a channel;
• Bid to relinquish a UHF channel to
move to either a high VHF (7 to
13) or low VHF (2 to 6) channel;
• Bid to relinquish a high VHF
channel to move to a low VHF
channel.
14. Results
• Winning broadcasters announced early April
• What we know
• Many “low bidders” in the initial allocations were public television stations
• Off-air stations announced so far are public/university stations
• Substantial benefits and costs for public TV
• Potential loss of universal service
• Channel sharing, relocation likely provide capital in excess of cost
20. Estimating Pubic TV Impact -- Data Overview
• Television ratings
• Weekdays for 4 weeks in February 2010
• Viewership shares averaged over half hour blocks, weekdays 5:00 to 8:00 pm
• Nielsen Media Research
• Local and cable stations, top 100 markets
• Advertising revenues: Kantar Media
• Weekdays for 4 weeks in February 2010
• Advertisement level data averaged over half hour blocks, weekdays 5:00-8:00pm
• Kantar Media
• Local stations only, top 100 markets
• Station characteristics
• Warren Communication Television and Cable Factbook

29. Structural analysis overview
• For welfare analysis, we need:
• Model of viewing
• Model of advertising
• Model of station competition for
viewers and advertising
• Results should illustrate how:
• Viewership, broadcast type, and ad
revenue change together.
• Broadcast decisions affect viewer &
advertiser surplus.
• Station profits adjust to
counterfactual broadcast choices.
