The channel utilization reflects the traffic volume of the air interface. A high channel utilization indicates a large service volume on an AP.

WLAN planning has requirements on signal field strength in coverage areas.

For example, the signal field strength in key areas ranges from -40 dBm to -75 dBm, and that in common areas exceeds -85 dBm.

An antenna converts pilot waves on transmission lines into electromagnetic waves propagated in unbounded media (free space in most cases), or vice versa.

In direct forwarding mode, user data packets are encapsulated in a CAPWAP tunnel and then forwarded by the AC to the upper layer network.

The management VLAN is used to transmit packets that are forwarded through CAPWAP tunnels, including management packets and service data packets forwarded through CAPWAP tunnels.

WLAN technology uses radio waves to transmit information over the air and uses the 2.4 GHz and 5 GHz frequency bands. The 5 GHz frequency band here refers to Fifth Generation (5G) technology.

To quickly identify the AC on which a STA goes online, an AC saves the online status of all ACS and STAs in the mobility group.

On a WL AN where there are only one AP and two STAs, the two STAs can hear each other but one STA is not in the coverage area of the AP. For the AP this STA is a hidden node.
