Future is shared spectrum:
decoupling of spectrum frequencies
from infrastructure investment & applications
Technology (Capabilities) 
frequency agility, expanded
capacity for sharing
Smart radio systems, spread
spectrum, transition to broadband
platform architectures
Revenue (Customer experience) 
24/7 availability, simplicity of use,
seemless mobility
Heterogeneous networks (3G/WiFi,
wireless/wired, global roaming)
Costs (Network provisioning) 
Bursty traffic, multimedia services,
lower costs, intermodal competition fat-tailed usage profiles
Policy (Spectrum reform) 
reduced artificial scarcity due to
legacy regulations
©Lehr, 2007
Transition to expanded flexible
market-based licensing and
unlicensed spectrum mgmt regimes

Mission: Promote Shared Spectrum Future
Regulatory Reform: from C&C to Markets
-- Flexible, tradable exclusive licenses
-- Dynamic shared spectrum (including commons)
Commercialization of innovative radio technologies
-- Co-engineer the ecosystem for DSA
-- Technology, business models, & markets
Raise awareness, engage multidisciplinary research
WORK TOWARD PRACTICAL SOLUTIONS!

(1) Band plan for 2.6GHz: 2-stage auction to allocate FDD/TDD
(2) Spectrum Usage Rights for Licensing (Interference Protection)
(3) More effective use of guard bands (auction masks?)
