Is a controller required?

Previously when planning a managed wireless network, a controller was required.

These costly devices controlled the functionality of the wireless APs and frequently the network would stop working if the controller failed.

In addition to the cost of the controller, there would be a maintenance contract to ensure a replacement was available.

As newer mobile devices are utilised, changes to controller operating software (firmware) was essential.

Instant APs

Aruba Instant APs (IAPs) include basic controller functionality, managing up to 80 APs without the need for a controller.

One of the IAPs is selected as a master and in the event of a failure another IAP takes over to keep your network operational.

Also you may opt for Central, Aruba’s cloud based management platform for enhanced functionality.

For larger campus networks Aruba offers Mobility controllers.

These devices manage authentication, encryption, VPN connections, IPv4 and IPv6 Layer 3 services, the Aruba Policy Enforcement Firewall, Aruba Adaptive Radio Management and Aruba RFProtect spectrum analysis and wireless intrusion protection.

Clustering and centralized management enable the deployment of large networks with hundreds of Mobility Controllers with minimal staff.

A master Mobility Controller can manage local Mobility Controllers, while Aruba AirWave network management provides enterprise-wide clarity and control through real-time monitoring, historical reporting and troubleshooting.
