Dissertation Talk: Towards Scalable Community Networks
Lecture | May 13 | 11 a.m.-12 p.m. | 405 Soda Hall
Shaddi Hasan, UC Berkeley
Over 400 million people live without access to basic communication services, largely in rural areas. Community-based networks, and particularly community cellular networks, can sustainably support services even in these extremely rural areas where commercial network operators cannot.
In this talk, I will identify key challenges these community cellular networks face for reaching scale, and present two approaches for addressing those challenges. The first, GSM Whitespaces, demonstrates that rural community cellular networks can safely share spectrum in bands occupied by incumbent mobile network operators, removing a key barrier to independent operation. The second, CCM, shows how community networks and incumbent mobile network operators can cooperate to share resources to extend service. We will explore each of these approaches through practical systems and longitudinal deployments of community cellular networks in Southeast Asia that provide service to thousands of rural people.
