rating; for example, a black enclosure gets much hotter in the sun compared to a white one. You can also use a
pressure vent to prevent moisture accumulation (see figure 20).
Areas with high vibration
If the AP is installed using a side arm type mount or other mounting locations where there is a probability
of high vibration, it is recommended that a padlock or metal pin be used to prevent the AP from vibrating
loose from the bracket.

Warehouse and Factory
Warehouse installations are often difficult because of the high ceilings and the clutter of the material being
warehoused. When performing a coverage check (site survey), always check the coverage at full stock
levels because the material being warehoused can change the RF coverage creating loss of uniform coverage.
Also, try to position the APs as close to the users as possible. If the AP is 30 feet in the air, that is 30 feet
farther, the signal has to go, best case. When configuring coverage for aisles, try to use directional (Patch)
antennas on the wall and shoot down the aisles. Or, use low−gain Omni−directional antennas on the ceiling
(such as dipoles) or mount the AP lower using pipe and electrical box mounting techniques. See the example
shown in Figure 21.
