In this paper we have presented a methodology for a rural and semi-urban telecommunication network placement. In order to optimally place the network and to ensure that the network is realistic and viable, we address four key issues, namely the demographic and socio-economic issues, geographical estimation, optimization of the network placement and financial optimization. A digital representation of the map of the region where the network has to be placed is used. A continuous optimization algorithm is applied to optimally place the backbone rings, and a combinatorial optimization algorithm is applied to obtain the optimal rollout order for the network. Mathematical formulations for both the optimization problems are presented. Optimal financial indicators are obtained.
