Working in unison with HP E-series MultiService Mobility Access Points, HP E-series MultiService Mobility Controllers deliver high-performing networking solutions for the mid-market. The enhanced architecture scales from IEEE 802.11b to 802.11n without requiring 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 small to large mid-market deployments, the E-series wireless controllers deliver a fast-roaming capability. Wireless security is comprehensive with support for internal and external authentication, authorization, and accounting (AAA) servers, built-in stateful firewall, per-user VLAN mapping, and mutual controller/access point (AP) authentication.
