Adaptive Radio Management

Hassle-free deployment with guaranteed service levels.

Aruba Adaptive Radio Management™ (ARM) technology optimizes 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.

Without disconnecting clients or disrupting applications, ARM™ automatically adjusts channel assignments on Aruba 802.11n APs. ARM is the only RF management technology certified to operate with voice-over-wireless traffic as it dynamically adapts RF scanning in the presence of latency-sensitive applications.

ARM ensures that Wi-Fi clients associate with the best channel, frequency and AP, making it the most effective RF management technology available today. By enforcing the fair distribution of bandwidth to mobile devices, ARM makes certain that data, voice and video 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 identify and classify Wi-Fi and non-Wi-Fi sources of interference.

Key ARM features include:

• Automatically assigns channel and power settings for all APs in the network.
• APs on the same channel share the spectrum without increasing co-channel interference to alleviate dense AP deployments in the 2.4-GHz band.
• Band steering load balances dual-band 802.11a/b/g/n clients between the 2.4- and 5-GHz bands to fairly allocate channel resources.
• Channel load-balancing evenly distributes clients across available channels in a given area to avoid overloading a single channel or AP.
• Airtime fairness ensures equal access for all clients, regardless of type, capability or operating system.
• Airtime performance protection ensures uniform performance by preventing slower clients from monopolizing resources.
• Coverage-hole detection notifies the network manager when clients are unable to associate with an AP at acceptable speeds.
