Issue Description
What Are Penetration Losses Caused by Various Obstacles?
Solution
Obstacles in the coverage area of an indoor or outdoor AP can cause an obvious loss of signals. The following table lists the path losses in 2.4 GHz and 5 GHz frequency bands caused by various obstacles.





If there are metal objects, load-bearing columns, or beams in the target coverage area, ensure that wireless signals are not blocked by them because they cause a large penetration loss.

The penetration loss is minimum when signals penetrate a wall vertically, and the penetration loss is much larger when wireless signals penetrate a wall obliquely. Therefore, when you install APs, try to reduce the incidence angle of signals.
