In WLAN networks, the 24 GHz frequency band is divided into 14 overlapping channels with a frequency width of 20 MHz (except 802.11b). Which of the following channels is a commonly used non- overlapping channel in existing networks?

In WLAN networks, omnidirectional antennas are mostly used in point-to-multipoint communication hubs because of their non-directional nature, while directional antennas are suitable for long-distance communication because of their directional nature.

Which of the following descriptions of WLAN network optimization measures is wrong?

Which of the following descriptions of WLAN network capacity optimization methods are correct?
(Multiple choice)

Multicast messages are sent at a low rate on the air interface. A large number of such messages will occupy a large amount of air interface resources, affecting the transmission of normal user service data packets. In scenarios without multicast services, when the service data forwarding method adopts tunnel forwarding, it is recommended to configure multicast message suppression on WAC. Which of the following configuration commands for the multicast packet suppression function is correct?
