Abstract
According to one embodiment of the present invention, provided is a frequency band (FB) determination method of a wireless access device which provides an access point to enable one or more terminals to wirelessly access a network. The method may comprise the steps of receiving database-related information from database servers which have database related to unused FBs of a television broadcasting band (TVBB), determining a database server to be accessed among the database servers on the basis of the database-related information, requesting the determined database server and receiving information on available FBs, and determining FBs, among the received operating FBs, for the one or more terminals. The operating FBs are determined by the database server so that the wireless access device can coexist with a neighboring homogeneous or heterogeneous wireless access device without mutual interference within the TVBB.
