A. STA roaming indicates the process in which STAs switch from one AP to another.

B. In both Layer 2 and Layer 3 roaming, STAs* IP addresses remain unchanged.

C. The APs used to implement WLAN roaming must be of the same model.

D. When an AC receives an association/re-association request, it determines that the STA roams if an entry about the STA already exists.

A. Radio resource management can improve user access security.

B. Radio waves will attenuate when they are transmitted over air, degrading service quality for wireless users. Therefore, radio resource management is needed.

C. Radio resource management enables a WLAN to adapt to changes in the radio environment by dynamically adjusting radio resources.

D. Radio resource management can improve Internet experience of users.
