Aruba Wireless

Instant-Access points Aruba — do not require a separate controller, but use a virtual controller, the functions of which are performed by one of the points. HPE Aruba Instant — is a solution that allows you to deploy «controllerless» enterprise WiFi network. It already has built-in network security, automatic management RF and enough smart features to run a complete solution without additional licensing. A cluster of access points is controlled using a virtual controller, which is located on one of the access points (IAP). The controller is responsible for the process of autoconfiguring new access points, authorization and authentication, guest access and network services (NAT, DHCP and etc.). 

Controllers Aruba (HPE) provide centralized management of wireless access points. In addition to their main function, they support WIDS/WIPS, can act as VPN concentrators, as well as firewalls with support for network address translation (NAT) and filtering at the application level (Layer 7).
