What is the correct description of the WLAN site survey for different typical scenarios?

A. The office surveys the main load-bearing columns and partitions to cover the impact. If it is an overall suspended ceiling, the AP should be considered as close to the maintenance port, if it is metal Ceiling, you can choose to place the AP under the ceiling or wall mount

B. If the wall of the school classroom is made of reinforced concrete, the signal attenuation is large. It is best to measure the attenuation when surveying. The teaching building should pay attention to the weak electricity room Set

C. The ward inspection scene has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, it is necessary to pay attention to the interference or disallow of medical equipment.Area with Wi-Fi signal

D. The stadium has a complicated environment and difficult wiring. Therefore, the weak house and the

wiring should be confirmed with the property. If the distance is too far, it may be considered.Adding an external switch, the survey should focus on mutual interference and installation methods between APs.
