What is a primary benefit of BSS coloring?

• A. BSS color tags improve performance by allowing APs on the same channel to be farther apart
• B. BSS color tags improve security by identifying rogue APs and tagging them as threats
• C. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference
• D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference

Answer: (D)

BSS coloring uses color tags to label transmissions from different Basic Service Sets on the same channel, so devices can tell whether a signal comes from the same BSS or a neighboring one. When a neighboring BSS uses a different color, the receiver treats that signal as non-cochannel interference and doesn’t defer as much, allowing more simultaneous transmissions. This spatial reuse improves throughput in dense deployments and effectively lowers the interference threshold that would normally limit performance. It’s not about security, rogue-AP detection, or controller-only configuration; it’s a channel-level mechanism to distinguish BSSs and boost capacity.
