IEEE 802.11-23/0888r0: TGbh WBA Liaison Response

Slide Note

The document discusses the mapping of TGbh use cases to WBA use cases, aiming to provide a response to a liaison request. It covers various WBA use cases such as network access restrictions, device diagnostics, network band steering, and more. Additionally, it outlines TGbh use cases related to client steering, device identification, home automation, security, and more. The status and scope of each use case are highlighted, indicating whether it falls within the project's purview. Overall, the goal is to achieve consensus on use case mapping for constructing an appropriate response.
