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 low‐ gain 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.)
