BSS Colouring

                                

When too many access points (APs) and clients hear each other on the same channel, it is called an overlapping basic service set (OBSS). For example, the tablet is trying to connect to the AP, and it founds 3 APs on the same channel, now the tablet is confused. This is signal interference.

The solution is BSS coloring, which is a method for identifying OBSS.

Now if different APs that operate on the same channel, each of them will have a color and tells the tablet, so the tablet knows which AP to connect and ignore the interface from the other APs. Now each client gets the best quality connection possible.

If you've ever lived in an apartment or close to your neighbors, this BSS coloring feature minimizes Wi-Fi conflicts with your neighbor and allows for interference mitigation.
