HOPE X – RF and Cellular talks

Filed under: free and open source, hacker culture, networks, telecom, wireless — larryang @ 2:48 PM

Community Owned and Operated Cellular Networks in Rural Mexico” – slides here. The presenters provide cellular service to rural Mexican communally governed communities.

The next day, the presenters had a workshop on “How to Build and Run Your Own Cellular Network“.

The equipment is less than ten thousand US dollars, running open source software. Its fairly small and easily placed on a tree or bamboo. There is quite a bit of software work to be done, especially services that involve interfacing with the publicly switched telephone and cellular network (PSTN).

Building an Open Source Cellular Network at Burning Man” by Geeks Without Borders – slides here. The presenters talk about how they provided service for a community of fifty thousand who appear overnight. Burning Man provides a good way for experimenting and testing for scenarios such as disasters and refugee camps.
