ABSTRACT

Recently, super Wi-Fi is getting growing interest as a fundamental information infrastructure for creating new business and industry as well as for public domains. Super Wi-Fi has a great advantage of remarkably extending spatial coverage of the existing Wi-Fi technology by utilizing low-frequencies for TV white spaces. Due to this characteristic of the super Wi-Fi, it could be suitable wireless infrastructure for less accessible areas to the Internet such as rural areas. This paper addresses the optimal facility location problem of wireless regional area network (WRAN) for super Wi-Fi which has a much wider coverage than the standard Wi-Fi service. For modeling, we developed a bi-objective optimization model that enables to consider spatial efficiency and spatial equity of demand in a flexible framework. Also, we suggested several locational solutions of super Wi-Fi according to various scenarios of the potential sites including radio frequency and signal strength restrictions. The suggested spatial solutions of super Wi-Fi with wide area coverage will be viable option to mitigate spatial unevenness of wireless infrastructure effectively. Also, visualizing various solutions based on demand and location scenarios with cost and coverage aspects will be very useful for central/local government decision makers who wish to adopt the super Wi-Fi technology.
