Own the Air: Testing Aruba Networks’ Adaptive Radio Management (ARM) in a High-Density Client Environment
Radio frequency (RF) management is a challenging endeavor, and nowhere more so than in dense WLAN environments. The problems are manifold: Legacy clients take too much air time. Channels get saturated. Noise on one channel spills over into others. Clients get distributed unfairly across bands and channels. These problems all produce the same result: degraded application performance in high-density environments.
Aruba Networks’ Adaptive Radio Management (ARM) features aim to boost application performance for 802.11n and legacy clients, especially in high-density environments such as offices, conference rooms, and lecture halls. The ARM features, which are included as part of the base ArubaOS available on every Aruba Mobility Controller, introduce new mechanisms for managing air time and dynamically balancing clients across bands. The ARM features require no change on WLAN clients.
Aruba commissioned Network Test to evaluate the efficiency of ARM features. Using a massive (80-client) over-the-air test bed1, Network Test assessed ARM features both individually and in concert, in the latter case using strict adherence to service-level agreements as one of the key metrics.
