The following is a statement about the WLAN room sub-channel planning. What is wrong?

A.

Confirm the local available channel with the customer before planning

B.

The same channel is the same as the channel sent by the antenna connected to the AP.

C.

Huawei's room AP6310 supports channel planning for 2.4G and 5G bands simultaneously.

What is the correct description of using dynamic load balancing in high-density scenarios?

A.

The purpose of 5G priority access in the AP is to reduce the 2.4G load and provide overall system performance.

B.

Load balancing is suitable for high-density wireless network environments to ensure reasonable access of STAs.

C.

Load balancing between APs, based on load balancing of access users or traffic, optimizing the distribution of terminals in the entire network and improving user experience.

D.

Dynamic load balancing can be divided based on three factors: number of users, traffic, and type of service.

E.

The APs that enable load balancing must be connected to the same AC, and the STAs can scan the SSIDs of APs that are load balanced with each other.

Regarding the operation flow of the WLAN Planner network tool, what is the following description correct?

A.

B.

New Project -> Import Drawing -> Set Environment -> Deploy AP -> Signal Simulation

C.

Import Drawing -> New Project -> Deploy AP -> Set Environment -> Signal Simulation

D.

New Project -> Import Drawing -> Deploy AP -> Set Environment -> Signal Simulation

Dual link characteristic switch

B.

IP and priority of the respective AC

C.

Load status of each AC

D.

Configuration files of the respective ACs

E.

Forwarding mode of each service set of AC

The directional antenna can not only improve the signal strength of the downlink AP, but also improve the signal strength of the uplink terminal received by the AP.

A.

True

B.

False

What are the precautions in using the WLAN Survery PAD survey tool for pre-sales network planning?

A.

There must be a survey of the construction environment and know the corresponding scale

B.

Label the obstacle information as detailed as possible, keeping it consistent with the actual environment.

C.

The customer's needs must be clear, and the actual number of people needs to consider the concurrency rate according to the actual situation.

D.

For some unclear information, the surveyor is required to estimate relevant information for surveying.
