Adaptive Radio Management
Alcatel-Lucent’s Adaptive Radio Management (ARM) takes the guesswork out of RF management by using
automatic, infrastructure-based controls to maximize client performance and enhance the stability and
predictability of the entire Wi-Fi network.

Understanding ARM
Alcatel-Lucent'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 Alcatel-Lucent AP in its current RF environment.
Alcatel-Lucent’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
