Radar Overview

Radar is a set of advanced, intelligent features for managing the wireless environment. Radar includes advanced features for:

• Device location tracking
• Wireless-Intrusion-Detection and Wireless-Intrusion-Prevention (WIDS-WIPS)
• Advanced load balancing capability

Radar provides a basic solution for discovering unauthorized devices within the wireless coverage area. Radar performs basic RF network analysis to identify unmanaged APs and personal ad-hoc networks. The Radar feature set includes: intrusion detection, prevention and interference detection.

All APs can provide WIDS and traffic forwarding functionality, simultaneously and, if configured to do so, will apply countermeasures to detected wireless intrusions.

All APs (except 3705) can be placed in Guardian mode. In this mode, the AP dedicates both radios for intrusion detection and prevention functions. Guardians are capable of detecting and mitigating attacks on wireless channels that are not being used for traffic forwarding by the authorized network.

When controllers are configured in an availability pair, the Radar feature operates in High Availability mode, allowing Radar to retain its configuration, historical, and runtime data in the case of an availability pair controller failure. In High Availability mode, the configuration and runtime on both controllers is synchronized.
