The following is true about the AP installation location?

For aesthetic needs, priority can be given to placing the AP on the ceiling.

If the site is a monolithic ceiling, the AP should be considered as close to the maintenance port.

The material of the ceiling is generally thin, and the impact on the cover is negligible.

When wall-mounting or installing under the ceiling, it may be necessary to punch holes. When surveying, try to confirm with the property whether it is feasible.
