Adaptive Radio Management
Employs infrastructure-based controls

Hassle-free deployment with guaranteed service levels.

Aruba Adaptive Radio Management (ARM) technology employs infrastructure-based controls to optimize Wi-Fi client behavior and automatically ensures that Aruba access points (APs) stay clear of interference, resulting in a more reliable, higher performance wireless LAN infrastructure.

Without disconnecting client devices or disrupting business-critical applications, ARM automatically adjusts 802.11 channel assignments on Aruba 802.11n APs. ARM is the only dynamic RF management capability that is certified to operate in the presence of voice-over-Wi-Fi traffic as it dynamically adapts RF scanning in the presence of latency-sensitive applications.

ARM is the most effective RF management solution in helping Wi-Fi clients associate with the best channel, best frequency and best AP. By ensuring the fair distribution of available Wi-Fi bandwidth to mobile devices, ARM ensures that data, voice and video applications have sufficient network resources at all times.

ARM can be used in conjunction with the Aruba RFProtect Spectrum Analyzer. While ARM optimizes client behavior and ensures that APs stay clear of interference, the RFProtect Spectrum Analyzer utilizes Aruba 802.11n APs to remotely identify and classify Wi-Fi and non-Wi-Fi sources of interference.

Key ARM features include:

• Adaptive power and channel assignments - Automatically assigns channel and power settings for all APs in the network. Automates many set-up tasks during network installation and during ongoing operation as the level of Wi-Fi interference and RF noise change.
• Coordinated access to a single channel - Allows nearby APs on the same channel to share spectrum without increasing co-channel interference. Overcomes the challenges of dense AP deployments in the 2.4-GHz band.
• Band steering - Load balances dual-band 802.11a/b/g/n wireless clients between 2.4- and 5-GHz frequency bands in order to ensure fair allocation of 802.11 channel resources within the wireless LAN.
• Channel load balancing - Ensures the even distribution of clients across available channels in a given area to avoid overloading a single channel or AP.
• Airtime fairness - Provides equal access to the wireless medium for all clients, regardless of client type, capability, or operating system. The result is uniform performance for all wireless LAN clients
• Airtime performance protection - Delivers uniform performance by preventing clients - especially slower ones - from monopolizing resources.
• Coverage hole detection - Detects and notifies the network manager when clients are unable to associate at acceptable speeds.
