Scenarios
DSA
Low cost bulk data transfer
Disagreement about whether “non-time-sensitive” is a critical attribute
Wireless content distribution
YouTube on your Zune
Sync media files among cars/devices of a group of friends/family
SCSO (Self-Configured Self-Optimized)
1000 radios in the home
Multi-standard sensor networks
Both
“Free” peer-to-peer network with your friends/neighbors (Microsoft UPN)
Post-disaster communications for all the civilians
flash crowds on steroids
Bridges to link together mesh “islands”

How to define success
DSA
Significant increase in spectrum occupancy
Large-scale field test: add many secondary users to an existing spectrally
crowded area
no interference to primary users
secondary users can communicate
SCSO
Significant increase in spectral efficiency
Large-scale home networking test
add a new set of radios/applications to a large home network (many 100s)
system seamlessly adapts, no interference to neighbors, all app needs met
Both
Affordable mobile videophone for many simultaneous users
