cisco clean air vs aruba

Hi

What are the equivalent functionality of cisco clean air in aruba. What action can take by aruba controller if there is co-channel interference

Thank you

Re: cisco clean air vs aruba

Aruba has Adaptive Radio Management (ARM).



"Aruba's Adaptive Radio Management (ARM) technology maximizes WLAN
performance even in the highest traffic networks by dynamically and
intelligently choosing the best 802.11 channel and transmit power for each
Aruba AP in its current RF environment.

Aruba's ARM technology solves wireless networking challenges such as large
deployments, dense deployments, and installations that must support VoIP or
mobile users. Deployments with dozens of users per access point can cause
network contention and interference, but ARM dynamically monitors and
adjusts the network to ensure that all users are allowed ready access. ARM
provides the best voice call quality with voice-aware spectrum scanning and
call admission control.

With earlier technologies, network administrators would have to perform a
site survey at each location to discover areas of RF coverage and
interference, and then manually configure each AP according to the results
of this survey. Static site surveys can help you choose channel and power
assignments for APs, but these surveys are often time-consuming and
expensive, and only reflect the state of the network at a single point in
time. ARM is more efficient than static calibration, and, unlike older
technologies, it continually monitors and adjusts radio resources to provide
optimal network performance. Automatic power control can adjust AP power
settings if adjacent APs are added, removed, or moved to a new location
within the network, minimizing interference with other WLAN networks. ARM
adjusts only the affected APs, so the entire network does not require
systemic changes."

You want me to let you on a secret?  Nobody can do anything about interference besides change channel.  Aruba has been doing that for many years: Here is a manual from 2007:
