RRM Profile

Context

WLAN technology uses radio signals (such as 2.4 GHz or 5 GHz radio waves) as transmission medium. Radio waves will attenuate when they are transmitted over air, degrading service quality for wireless users. Radio resource management enables a WLAN to adapt to changes in the radio environment by dynamically adjusting radio resources. This improves service quality for wireless users.

Procedure

Create an RRM profile.

Choose Configuration > Wireless Services > Profile > Radio Management > RRM Profile. The RRM Profile List page is displayed.
Click Create. The Create RRM Profile page is displayed.
Enter the name of the new RRM profile in Profile name.
To copy all parameters from another profile to the new profile, select the name of the profile in Copy parameters from other profiles. If None is selected, parameters are not copied from another profile.
Click OK. The parameter setting page of the new RRM profile is displayed.

Set parameters for creating an RRM profile. Table 1 describes the parameters for creating an RRM profile.
