What: Kurtis Heimerl: GSM White Space: Spectrum Regulation in Support
of Community Cellular Networks
When: Tuesday, October 22th at 12 noon
Where: The Allen Center, CSE 203
Join us for this weeks Change talk by Kurtis Heimerl on his continued
work with community cellular networks and the future small micotelcos.
*Abstract*
Community Cellular Networks, small scale community-operated microtelcos,
have the potential to bring cellular coverage to the remaining 700
million people in rural areas without it. The deployments of two real
world networks, our Papua network and Rhizomatica's Oaxaca network,
support this vision. However, hurdles remain. One primary limitation is
regulatory; the Papua network is running without a spectrum license and
the Oaxaca network is limited to a 2-year experimental non-profit
license. Instead, major nation-scale carriers own this spectrum and are
reluctant to share it. In this work, we propose a mechanism, GSM White
Space (GSMWS), for allowing secondary community cellular networks to
operate in licensed bands with no negative impact to existing carriers.
GSMWS uses cognitive radio designs to co-operate in the same bands as
existing carriers. I will detail our early progress on these designs and
future work.
*About the Speaker*
Kurtis Heimerl is a PhD candidate at UC Berkeley working under Eric
Brewer in EECS and Tapan Parikh in the iSchool. His work focuses
primarily on cellular systems and their intersection with international
development. He is interested in Education, having worked on the
Metamouse group learning program, Crowdsourcing, winning Best Paper at
CHI for work on Kiosk-based crowdsoucing systems, and cellular systems
for rural areas, winning the Community award at NSDI. He will be
graduating in the winter and is very excited about the future of rural
connectivity.
