B.

Observe the AP and antenna installation method for the site.

C.

Every site needs to pay attention to the location of the weak house

The United States complies with the FCC standard. In an outdoor road scenario, an AP8030DN uses channels 1 and 149 for road coverage, and a single spatial stream terminal is connected. In the case of considering the MIMO gain, regardless of the feeder loss, what is the maximum transmit power of the AP 2.4 GHz and 5 GHz, respectively?

A.

2.4GHz -22dBm, 5GHz -20dBm

B.

2.4GHz -21dBm, 5GHz -15dBm

C.

2.4GHz -20dBm, 5GHz -14dBm

D.

2.4GHz -20dBm, 5GHz -20dBm

The following is about using the AP6310SN to create a new WLAN room subsystem. What is wrong with this?

A.

The number of antennas in a single AP band is 4~8, and it is recommended that no more than 10 antennas under normal circumstances.

B.

Under normal circumstances, the distance between the AP and the far-end room subantenna is controlled within 50 meters, and it is recommended not to exceed 60 meters.

C.

In a typical room sub-scenario, it is recommended that the output power of each antenna be basically the same, and the output power is controlled at 12~18dBm. The specific power selection and field Strong demand is related to the wall structure

D.

There is interference between the room division antennas of the same AP, so it cannot be placed intensively according to requirements.

A.

True

B.

False

C.

X1E with board AC

D.

ACU2

Use the AP8130DN external H33_V33_13dBi directional antenna to meet the basic services such as browsing the webpage under the FCC limit, and the farthest coverage distance
What is the approximate amount?

The AP number is calculated only from the bandwidth without considering other factors such as attenuation and interference. Take 802.11n as an example: the measured rate of each AP. About 100Mbps, there are 10 office areas in an office building, 40 people per office area, and customers require bandwidth per terminal. 2Mbps, all users online companion rate is calculated according to 70%, how many APs are needed for the office building?

A.

4

B.

5

C.

6

D.

7

The following figure is a typical WLAN networking diagram. Which of the following is correct about this figure?

A.

This network diagram is the data forwarding mode of the datagram. All data packets in the figure are not AC.

B.

All management messages must be forwarded through the tunnel.

C.

All signaling packets can be forwarded directly without forwarding through the tunnel.

D.

The wireless user service data in this network needs to be converted to 802.3 and 802.11 packets on the AC, and then through the upstream aggregation switch. Forwarding
