1. ©Lehr, 2007 Spectrum Policy Working Group William Lehr (wlehr@mit.edu)wlehr@mit.edu Communications Futures Program Massachusetts Institute of Technology CFP Meeting hosted by Comcast Philadelphia, PA May 30-31, 2007 Industry co-chair: Mike Chartier, Intel

2. ©Lehr, 2007 2 Future is shared spectrum : decoupling of spectrum frequencies from infrastructure investment & applications Smart radio systems, spread spectrum, transition to broadband platform architectures Technology (Capabilities)  frequency agility, expanded capacity for sharing Heterogeneous networks (3G/WiFi, wireless/wired, global roaming) Revenue (Customer experience)  24/7 availability, simplicity of use, seemless mobility Bursty traffic, multimedia services, fat-tailed usage profiles Costs (Network provisioning)  lower costs, intermodal competition Transition to expanded flexible market-based licensing and unlicensed spectrum mgmt regimes Policy (Spectrum reform)  reduced artificial scarcity due to legacy regulations

3. ©Lehr, 2007 3 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!
