In what role might a WLAN be used within a distribution layer?

A Wireless Local Area Network (WLAN) can serve as a building-to-building bridge within the distribution layer by facilitating communication between different buildings on a campus or larger geographical area. This is particularly beneficial in environments where laying physical network cables is impractical or cost-prohibitive. By using WLAN technology, data can be seamlessly transmitted over the air, connecting separate buildings to a cohesive network.

Furthermore, the distribution layer is responsible for aggregating data from access layer switches and directing it towards the core layer. The use of WLAN in this context enhances flexibility and scalability, allowing for efficient management and integration of network resources across multiple locations. This role supports the dynamic needs of a modern network, where mobility and ease of access are crucial.

In contrast, using WLAN solely for internet access, functioning as a core network segment, or focusing exclusively on video conferencing does not leverage the broader benefits of bridging communication over distances, which is a primary advantage of WLAN technology in a distribution layer scenario.
