Description

Amendment Standard – Superseded. This amendment specifies enhancements to the IEEE 802.11 medium access control (MAC) that support wireless local area network (WLAN) interworking with external networks. It enables higher layer functionalities to provide overall end-to-end solutions. The main goals of this amendment are aiding network discovery and selection, enabling information transfer from external networks, enabling emergency services, and interfacing subscription service provider networks (SSPNs) to IEEE 802.11 networks that support interworking with external networks.
