A.

Google Earth

B.

Bitmap (jpg, gif, bmp, etc.)

What are the general methods of WLAN planning?

A.

Demand collection

B.

Product selection

C.

Business negotiation

D.

The following description of the steps for Layer 2 roaming is wrong?

A.

The STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.

B.

AP2 responds by sending a response on channel 6 after receiving the request in channel 6 (the channel used by AP2)

C.

The STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.

D.

The STA sends an association request to AP2 through channel 6, and AP2 responds with the association response to establish an association between the user and AP2.

The following is the correct statement about the requirements for confirming the on-site environmental information during the WLAN site survey process?

A.

Confirm whether the site is completely consistent with the architectural drawings, and highlight the inconsistent areas, try to take photo records, and mark them in the drawings.

Room number on site

B.

Take photos of the scene as thoroughly as possible in the room, especially the installation location of the equipment, the overall coverage area, the internal building structure, and new obstacles.

Focus on the outdoor coverage, only need to focus on the obstacles between the AP and the coverage area.

C.

In the indoor survey, the obstacle type is distinguished from the drawings, and the actual position and material of each type of obstacle are marked. Different obstacles are used differently.

Color marking and testing its 2.4G and 5G attenuation values

D.

During indoor survey, pay attention to other obstacles that are not drawn but affect the covering effect, such as load-bearing columns and artificially added partitions during decoration.

Large objects such as broken and suspended ceilings

E.

Outdoors need to pay attention to the height and shielding range of obstacles on the site. For irregular obstacles (such as trees), try to take photo records.
