A method for selecting an optimized bandwidth for a geo-location controlled (GDC) station (STA) which does not have location determining capability includes: analyzing first statistical data indicating a bandwidth which is widely deployed across regions; and selecting that bandwidth as the optimized bandwidth. The method further includes checking a configuration file of the GDC STA to determine country information of where the GDC STA was sold; and selecting either a bandwidth corresponding to the country or selecting the bandwidth which is most widely deployed across regions according to the first statistical data as the optimized bandwidth.
