Working with HP MultiService Mobility Access Points, HP MultiService Mobility Controllers deliver a high-performance networking solution. The enhanced architecture scales from IEEE 802.11b to 802.11n without expensive controller upgrades. Robust identity and roles-based user account profiles, as well as Virtual Service Communities (VSCs) with independently configurable Quality of Service (QoS), authentication, encryption, and VLAN support, deliver intelligence to the edge of the network. Scalable from branch offices to large organizations, the controllers deliver fast-roaming and ultraspeed hand-offs. Wireless security is rock solid with support for the internal and external authentication, authorization, and accounting (AAA) servers, built-in stateful firewall, per-user VLAN mapping, and mutual controller/access point (AP) authentication.
