Why are WLANs typically deployed in an access capacity rather than as the core layer of a network?

WLANs, or Wireless Local Area Networks, are generally deployed in an access capacity, primarily because they face significant challenges in terms of stability and speed that are crucial for the core layer of a network. The core layer is responsible for high-speed data processing and routing, as it connects various parts of the network and often handles large volumes of traffic and data.

Wireless technologies tend to experience issues such as interference from physical obstacles, signal attenuation, and variability in performance based on environmental factors and user density. These challenges can lead to latency and reduced reliability, which are not suitable for core network functions that demand consistent, high-speed connections.

In contrast, wired connections, which are typically used in the core layer, can provide the necessary bandwidth, stability, and lower latency that are essential for backbone infrastructure. Thus, while WLANs provide flexibility and convenience for end-user access points within a network, they do not maintain the same level of performance as wired solutions required for core operations.
