Centralize WLAN gateway services within an on-premises Aruba Networking environment using the 91xx gateway platform. The Advanced Plus Security configuration addresses deployments where wireless gateway operation and security functionality are maintained within the local infrastructure rather than placed solely in a cloud-managed service. Its scope is WLAN gateway infrastructure, not an access point, switch, or standalone endpoint. The 91xx designation identifies the gateway platform associated with this offering. It fits wireless architectures that use a central gateway role to support WLAN services across the environment. This makes it relevant when gateway placement, centralized wireless policy handling, and on-premises operational control are part of the network design. HPE S8N28AAE specifically identifies the Advanced Plus Security configuration for the Aruba Networking Central On-Premises Gateway 91xx offering. The Advanced Plus Security designation distinguishes this configuration from gateway options without that named functionality. Match the ordering code to the required 91xx gateway deployment and the intended Advanced Plus Security feature scope before deployment.
