Metal Pins or Padlocks for Areas of High Vibration
Warehouse and Factory
Warehouse installations are often difficult because of the very high ceilings and the clutter of the
material in storage. As part of your site survey, always check the coverage when the warehouse is fully
stocked, since the material in storage can change the RF coverage and interfere with uniform coverage.
For aisles, use directional (patch) antennas on the wall and shoot down the aisles. You can also use
lowgain omnidirectional antennas (such as dipoles) on the ceiling or units with integrated antennas; high
gain omnidirectional antennas tend to have more nulls. (See
Figure
50.)
The higher the AP is mounted, the farther the signal must travel. Use pipe and electrical box mounting
techniques to lower the AP (external and internal antenna models) so that it is closer to users. (See
Figure
29.)
