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