1. A frequency band determination method of a wireless access device which provides an access point to enable one or more user equipments to wirelessly access a network, the frequency band determination method comprising the steps of:

  • receiving, by the wireless access device, first database-related information from a first database server and second database-related information from a second database server when two or more database servers exist,wherein the first database-related information includes one of a first database index, a first database access fee or a first database geo-location resolution, andwherein the second database-related information includes one of a second database index, a second database access fee or a second database geo-location resolution;

    transmitting, by the wireless access device, the first and the second database-related information to a user equipment connected to the wireless access device;

    receiving, by the wireless access device, a request message from the user equipment;

    based on the request message, determining, by the wireless access device, a database server to be accessed among the first and second database servers;

    receiving, by the wireless access device from the determined database server, one or more available frequency bands for exchanging information with the determined database server; and

    determining, by the wireless access device, one or more frequency bands, among the received one or more available frequency bands, to exchange data between the determined database server and the user equipment via the wireless access device,wherein the one or more available frequency bands are identified by the determined database server so that the wireless access device can coexist within a television broadcasting band with a neighboring homogeneous or heterogeneous wireless access device without mutual interference.
