I recently attended HOPE X in NYC and really enjoyed this presentation on community owned cellular networks in rural Mexico.
You can find out more about Rhizomatica at http://rhizomatica.org/.
(41 mins) Why try to avoid them spying on us on their networks when we could just build our own? This is what the Rhizomatica project has done in rural Mexico, where they help to build and maintain community owned and operated GSM/cellular infrastructure. Come and hear about experiences in the field and how to deal with the technological, legal, social, and organizational aspects that come along with operating critical communications infrastructure from a community emancipation and autonomy perspective. If you enjoy freedom, community, and dismantling the corporations and governments that seek to monitor, control, and exploit us, then this presentation is for you.
