Fixed broadband wireless access is a promising technology allowing
Internet service providers to expend their customer base in sparsely populated
rural areas. Because the size of the target service area is humongous, relay in-
frastructure is essential. Installing and maintaining this relay infrastructure is
the main cost associated with such networks. Thus, we develop an optimization
fr a mework which computes the minimum number of relay stations and their cor-
responding channel confi gurations such that a pre-specifi ed subscribers’ traffi c
demand can be satisfi ed. Since the problem is a mixed-integer program, we pro-
pose an effi cient optimization algorithm to compute the optimal solution in a
reasonable amount of time. Our numerical results show that by using a few relay
stations in a rural community, broadband Internet access can be established in a
cost effective manner.
