Talk Title: Frontier Networks: Context, Challenges, and Connectivity
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium.
In this talk, I discuss Frontier Networks -- networks that expand Internet access to disconnected regions -- and their role in scaling Internet access to the half of the global population that remains offline. I describe how a deep understanding of the context and challenges reveals new approaches to building more reliable, cost-effective, and manageable Frontier Networks. I describe a project I led to build such a network in a previously-disconnected region of Mendocino County, CA, the lessons it taught us about network design and operation, and the systems we built to address the needs that were unmet. I then describe three subsequent challenges -- bootstrapping, planning, and routing -- and describe ongoing projects to address them.
