The following is true about the WLAN side-by-side networking.

A.

The hangover network can perform WLAN deployment without modifying the physical topology of the live network, which facilitates network transformation.

B.

When the network is bypassed, the AC can no longer bear the gateway of the service WLAN.

C.

Using the “side-by-side networking + direct forwarding” network architecture can reduce the burden on the AC and improve network forwarding performance.

D.

When the network is connected to the network, the AC can be connected to the aggregation layer or the core layer switch, but it must be the same network segment as the AP.

The following is true about the WLAN actual site survey in the trace (network cable or fiber), power supply is correct?

A.

Confirm the overall rules of the route, you need to confirm with the owner whether you can punch through the wall, whether you can take the open line, whether there is conditional hidden line, the network cable is

Do you want to use a wire slot or add a conduit?

B.

In the survey process, the length of the trace should be calculated according to the actual environment, and the length of the trace is not required.

C.

If the AP needs AC power supply, it needs to confirm the location of the power supply. If there are special requirements for the route in some locations, additional marking is required.

D.

In the outdoor scene survey, each outdoor AP installation location needs to consider the routing problem.
