BSS Coloring
The BSS color is a numerical identifier of the BSS. 802.11ax radios are able to differentiate between
BSSs using BSS color identifier when other radios transmit on the same channel. If the color is the
same, this is considered to be an intra-BSS frame transmission. In other words, the transmitting radio
belongs to the same BSS as the receiver. If the detected frame has a different BSS color from its own,
then the STA considers that frame as an inter-BSS frame from an overlapping BSS.
