In WLAN network, according to different channel bundling methods, it can be divided into several different types of channel working bandwidth: 40MHZ+, 40MHZ, 80MHZ, 80+80MHZ and 160MHZ.
Which of the following statements about the operating bandwidth of an 80 MHz channel is correct?

• A.80MHz is to bundle two non-contiguous 40MHZ channels together and select the higher frequency among the four 20 MHZ channels as the main channel
• B.80MHz is to bundle two consecutive 40MHz channels together and select one of the four 20 MHZ channels as the main channel.
• C.80MHz is to bundle two consecutive 40MHz channels together and select the higher frequency among the four 20 MHZ channels as the main channel.
• D.80MHz is to bundle two non-contiguous 40MHz channels together and select one of the four 20 MHZ channels as the main channel.

Each AC must be assigned a unique IP address. The APs attached to the AC device learn this IP address or the IP address configured on this interface for communication between the AC and AP in the ACHIT AP network and for establishing CAPWAP tunnels.
