White spot areas depict geographic locations which are not covered by mobile network operators. In Senegal, the Sylvo-pastoral hosted by Ferlo's region has a prominent role according to livestock transhumance. Nevertheless, this region is roughly covered by white spot areas. The lack of cellular network infrastructure is a pitfall for vital information dissemination for agro-pastoralists. Therefore, this paper describes the deployment and testbed performance evaluation in rural and urban environment of a LoRa-based COWShED communication architecture. By leveraging a mesh-based prof-of-concept, tangible results are obtained and thus promote several applications which overcome white spot areas limitations such as stakeholders geolocation, transhumance management, milk collection, etc.
