Community Cellular Networks (Oaxaca)
Indigenous-governed cellular infrastructure built in Oaxacan mountains when telecom companies deemed villages unprofitable—Srinivasan's paradigm of community-built dams.
In 2013, the Zapotec community of Talea de Castro in Oaxaca, Mexico, working with the nonprofit Rhizomatica, established an autonomous cellular network using open-source software and affordable hardware. The network provided voice and text service to communities that major telecommunications companies had deemed too remote and too poor to serve profitably. Governance was communal: pricing set by assembly consensus, coverage decisions made collectively, operations managed by locally trained technicians. Ramesh Srinivasan documented the networks as the clearest demonstration that communities can build and govern their own technological infrastructure when existing institutions fail to serve them—and as the paradigmatic alternative to top-down technology deployment.

Telcel and Movistar, Mexico's dominant carriers, had no commercial incentive to build towers serving villages of a few hundred people scattered across difficult terrain. The result was isolation: families separated by migration could not communicate, medical emergencies could not summon help, economic opportunities requiring coordination were foreclosed. The communities were not waiting
