Question No : 3

What are the considerations for using directional antennas in high-density scenarios? (Multiple choice)

A.Reduce the number of STA roaming times
B.Improve the business concurrency capability of adjacent cells
C.Control the signal coverage of a single AP
D.Reduce mutual interference between APs

정답:

Question No : 4

Which of the following options describe site surveys in different typical scenarios correctly? (Multiple choice)

A.Ward inspection scenarios have high requirements for coverage strength, roaming effect, and bandwidth requirements. At the same time, attention should be paid to interference from medical equipment or areas where Wi-Fi signals are not allowed.
B.The on-site environment of the stadium is complex and wiring is difficult, so the weak current room and wiring should be confirmed with the property. If the distance is too far, you may need to consider adding an external switch. The survey should focus on the mutual interference between APs and the installation method.
C.If the walls of school classrooms are made of reinforced concrete, the signal attenuation is relatively large. It is best to measure the attenuation during the survey. The location of the weak current room should be paid attention to in the teaching building.
D.The main load-bearing columns and partitions in the office survey affect coverage. If the ceiling is an integral one, the AP should be placed near the maintenance port as much as possible. If the ceiling is a metal ceiling, the AP can be placed under the ceiling or mounted on the wall.

정답:

Question No : 5

D.Signal frequency

정답:

Question No : 6

Which of the following options are the business demand characteristics of high-density venues? (Multiple choice)

D.The user only connects to a certain area and does not need to consider roaming

정답:

Question No : 7

dBm is a unit that indicates signal strength. Transmit power can be converted according to dBm units. Which of the following calculations are correct? (Multiple choice)

A.3 dBm = 2 mW
B.0 dBm = 1 mW
C.9 dBm = 4 mW
D.6 dBm = 3 mW

정답:
