The document discusses the need to clarify the definition of ESS Mesh. It reviews related concepts like BSS, DS, ESS and WDS based on IEEE 802.11 specifications. It recognizes that previous discussion may have incorrectly focused on WDS Mesh instead of ESS Mesh. Key questions are raised on how to properly define the relationship between WDS Mesh and ESS Mesh, and what exactly ESS Mesh means in terms of interconnecting ESSs, DSs and BSSs in a mesh configuration.
