An antenna converts pilot waves on transmission lines into electromagnetic waves propagated in unbounded media (free space in most cases), or vice versa.
OFDMA and MU-MIMO are mutually exclusive technologies that cannot be configured together.
The management VILAN is used to transmit packets that are forwarded through CAPWAP tunnels, including management packets and service data packets forwarded through CAPWAP tunnels.
In direct forwarding mode, user data packets are encapsulated in a CAPWAP tunnel and then forwarded by the AC to the upper-layer network.
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.
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.
