We proposed in this paper a free communication system for restoring a communal living and a minimum autonomy of operating in remote areas of developing countries. This system also intends to restore the return to local values, to strengthen the links between the populations, and to facilitate communication during epidemic or arm robber’s attacks in remote localities of developing countries; it also helps in a follow up of old people. Commercial Off-The-Shelf (COTS) components are used for global system nodes design. A covered area of 260m is reached and can be extended with dedicated additional antenna.
