community-oriented mobile phone infrastructure 

The Bricophone is a community-oriented mobile phone infrastructure in Open Source. It is a low cost, low energy, open hardware, open source project built for communities up to ten thousand people within regional distances. The characteristic of the Bricophone infrastructure is that it does not require any static infrastructure like relays, antennas, or digital data centers. This provides the opportunity for special uses in poor communities, mass rescueing in disastered areas, and cultural and social activities like festivals and other mass events.
