Cisco Aironet Series 3700 Access Point

Figure 92

Example of a Poor Installation – Access Point is too High and Buried in Conductive Foil

Remember, the best place for an AP is as close to the users as possible. Avoid metal or conductive objects in the near field (they
cause the radio waves to become directional and increases nulls (dead spots)). If you must mount the AP in a high ceiling, look
at directional antennas to direct (angle down) the signal to the intended target area and always mount dipoles in the correct
orientation.
