Why are WLANs usually deployed in an access capacity rather than the network core layer?

Why are WLANs usually deployed in an access capacity rather than the network core layer?

• A. Core layer demands very fast, stable, high capacity, no downtime.
• B. WLANs can meet core-level requirements with ease.
• C. Core layer must rely on wired connectivity exclusively.
• D. WLANs have insufficient security at the core.

Answer: (A)

The key idea is that the core backbone must deliver ultra-fast, highly reliable, high-capacity transport with almost no downtime. Wireless links, on the other hand, are inherently variable due to radio interference, client device differences, distance, and mobility as users move around. That variability makes wireless unsuitable for the backbone’s strict performance requirements. By placing WLANs at the access layer, you bring wireless connectivity directly to users while keeping the core wired, high-speed, and predictable. This separation also makes scaling and management easier and reduces the risk that wireless issues will impact the backbone. So the statement that the core layer demands fast, stable, high-capacity, no downtime best explains why WLANs sit at the access layer rather than in the core.
