Ceiling, you can choose to place the AP under the ceiling or wall mount

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

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

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.

Questions # 10:

What is wrong about the Fresnel region?

Options:

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

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.

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

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