How many dB of directional antenna attenuation is the main lobe width of the phenomenon?

A. 3

B. 4

C. 5

D. 6

Which of the following options is incorrect about the FIT AP description?

A. FIT AP is a traditional AP. In addition to providing basic wireless connectivity, it also provides security, management, and performance enhancements

B. FIT AP cannot be used in conjunction with AC

C. FIT AP differentiates from traditional FAT APs, providing only reliable, high-performance wireless connectivity, while stripping other features

D. FIT AP must be used in conjunction with AC

In the outdoor backhaul scenario, the line of sight is met and there is no interference requirement. When the return distance does not exceed 1km, the uplink bandwidth requirement is 0.5Mbps, and the EIRP is not Restricted, AP external antenna 17dBi_H65 degrees _V7.5 degrees, the maximum number of AT815SN docked by a single AP?

A. 16

B. 24

C. 32

D. 40

The following is not the rail transit business?

A. Passenger WIFI deployment

B. PIS system deployment

C. Indoor distribution system deployment

D. CBTC deployment

The following is the correct description of the AC deployment method?

A. AC deployment can be divided into two types: side-by-side deployment and direct-attached deployment.

B. The side-by-side networking is a superposition of the existing network. It has fewer modifications to the existing network and is quick and convenient to deploy. In addition, according to the control requirements for wireless users Choose direct forwarding or tunnel forwarding mode according to your needs

C. In the direct connection network deployment mode, because the AC is connected in series in the network, the management data and user data between the AP and the AC must pass CAPWAP tunnel forwards

D. Direct connection networking is mainly used in large campus network scenarios. The AP size in the network is recommended to be 1000 or more.

What is the correct description of the indoor distribution type AP6310SN?

A. The power splitter has multiple interfaces. When signals enter from any one interface, they are equally divided into multiple signal outputs.

B. When the AP is at the center of the room division network, it is recommended to use a single power splitter for direct splitting.

C. When the AP is at one end of the room division network and the coverage area is large, it is recommended to use a coupler for signal splitting.

D. Power splitters and couplers cannot be used in the same network at the same time

Regarding the installation and deployment of the room AP, what is wrong with the following statement?

A. The remote access unit of the AD9430DN can be panel mounted

B. The room divider antenna needs to be separated from the operator's antenna

C. AP installation location should pay attention to normal heat dissipation, no dripping, rat urine, etc.

D. Since multiple remote access units of the AD9430DN work on the same channel, this solution can effectively improve the terminal roaming effect.

On the Huawei chassis switch S12708, the ACU2 board has a larger AP capacity than the X1E board.

A. True

B. False

What is wrong about the Fresnel region?

A. The Fresnel zone of the radio beam is an ellipsoidal region that surrounds the visible line of sight directly.

B. The antenna installation position should ensure that the two nodes of the link are visible, and try to ensure that there is no obstruction in the Fresnel zone.

C. Two nodes of the site link are visible, and the Fresnel zone boundary is blocked, which will not affect the link transmission effect.

D. The distance between the stations is 2 kilometers, and the radius of the Fresnel area is about 6 meters.

In the coverage area, only the area where the field strength is required is selected (B), and the area with the specified number of bandwidth requirements is selected (A), and there is no concern whether there is a signal. Area selection?

A. Key coverage areas

B. Ordinary coverage area

C. Blind area
