The WLAN interface can be configured as either an access point (AP) or as a station. See the 7705 SAR-Hm and SAR-Hmc Interface Configuration Guide for information about the AP and station and how to configure them.
When configured as an AP, the WLAN interface provides SAP-level connectivity to the traffic it sends and receives over the interface from devices that are connected to it. The WLAN AP traffic can be transported over a service to remote locations; for example, to a remote WLAN gateway.
When configured as a station, the WLAN interface operates as a network interface to transport services over WLAN toward a remote AP. The node uses GRE-MPLS encapsulated SDPs to provide Layer 3 transport over the WLAN station interface.
