In this paper, we study the cell planning problem for a two-tier cellular\nnetwork containing two types of base stations (BSs)-- i.e. with fiber backhaul,\nreferred to as wired BSs (W-BSs), and BSs with wireless backhaul, referred to\nas unwired-BSs (U-BSs). In-band full-duplex wireless communications is used to\nconnect U-BSs and W-BSs. We propose an algorithm to determine the minimum\nnumber of W-BSs and U-BSs to satisfy given cell and capacity coverage\nconstraints. Furthermore, we apply our proposed non-dominated sorting genetic\nalgorithm II (NSGA-II) to solve both cell planning and joint cell and backhaul\nplanning problem to minimize the cost of planning, while maximizing the\ncoverage simultaneously. Additionally, the considered cell planning program is\ndeveloped into an optimization by including the problem of minimizing the cost\nof fiber backhaul deployment. In order to analyze the performance of the\nproposed algorithm, we study three different deployment scenarios based on\ndifferent spatial distributions of users and coverage areas. The results show\nthe superiority of our proposed NSGA-II algorithm for both cell planning and\njoint cell and backhaul planning to other well-known optimization algorithms.\nThe results also reveal that there is a trade-off between cell deployment costs\nand SINR/rate coverage, and W-BSs are placed in congested areas to consume less\nresources for wireless backhauls. Similarly, a trade-off between cell and fiber\ndeployment costs and SINR/rate coverage is observed in planning. We show that\nfor realistic scenarios desirable solutions can be selected from the Pareto\nfront of the introduced multi-objective problem based on given cellular\noperator policies.\n
