Wireless Mesh Network is presented as an appealing solution for bridging the digital divide between\ndeveloped and under-developed regions. But the planning and deployment of these networks\nare not just a technical matter, since the success depends on many other factors tied to the\nrelated region. Although we observe some deployments, to ensure usefulness and sustainability,\nthere is still a need of concrete design process model and proper network planning approach for\nrural regions, especially in Sub-Saharan Africa. This paper presents a design methodology to provide\nnetwork connectivity from a landline node in a rural region at very low cost. We propose a\nmethodology composed of ten steps, starting by a deep analysis of the region in order to identify\nrelevant constraints and useful applications to sustain local activities and communication. Approach\nfor planning the physical architecture of the network is based on an indoor-outdoor deployment\nfor reducing the overall cost of the network.
