1. one kind is the method for WLAN (wireless local area network) (WLAN) equipment unit radar idle channel table run at 5GHz frequency spectrum, wherein said frequency spectrum is divided into the first sub-band 5150-5250MHz, the second sub-band 5250-5350MHz and the 3rd sub-band 5470-5725MHz, it is characterized in that, described method comprises:

  • With the channel that adjustment region allows, for described spectral combination allows channel table;

    With the described permission channel with the accepted level that current WLAN transmits, combination BSS idle channel table;

    If described permission channel table comprises from described the first, the second, and the channel of the 3rd sub-band, so determine whether described BSS idle channel table contains less than two channels;

    If so, so from described permission channel table, select three channels, wherein the first channel is selected from described first sub-band, and second channel is selected from described second sub-band, and the 3rd channel is selected from described 3rd sub-band;

    If not, so from described BSS idle channel, select three channels, wherein the first channel is selected from described first sub-band, and second channel is selected from described second sub-band, and the 3rd channel is selected from described 3rd sub-band;

    If described permission channel table comprises the channel from described first and second sub-bands, so determine whether described BSS idle channel table contains less than two channels;

    If so, so from described permission channel table, select three channels, wherein the first channel is selected from described first sub-band, and second channel is selected from described first sub-band, and the 3rd channel is selected from described second sub-band;

    If not, so from described BSS idle channel, select three channels, wherein the first channel is selected from described first sub-band, and second channel is selected from described first sub-band, and the 3rd channel is selected from described second sub-band;

    If described permission channel table contains only from the channel of described first sub-band, so determine whether described BSS idle channel table contains less than two channels;

    If so, so in described first sub-band, from described permission channel table, two channels are selected;

    If not, so in described first sub-band, from described BSS idle channel table, select two channels.
