• Question 11:

  On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely to occupy channels as the number of online users increases. As a result, network quality deteriorates. To ensure network access experience of online users, Calling Access Control (CAC) can be configured. CAC allows an AP to control user access based on the CAC thresholds set according to the radio channel usage, number of online users on a radio, or terminal signal-to-noise ratio (SNR), ensuring network access quality of online users.

  B. FALSE

  Correct Answer: A
