Figure 104 Multi-Floor Schematic
Shows a floor configuration so that the WherePort IV field extends into the second floor.
8.4. Multi-Floor Installations
When activities are tracked on several floors, the vertical position of the WherePort IV and the extent of
its field must be carefully considered. If the field extends into the floor above, a tag moving on the upper
floor may be activated by the WherePort IV on the lower floor. This will produce an incorrect location
for the tag.
The height of the floor together with the utility space between floors must be considered so that the
WherePort IV is mounted at a height that prevents tags on the floor above from being activated (Figure
104).
The WherePort IV power setting can be set so that the range is reduced. The tags may also be mounted
lower on the asset to permit lower placement of the WherePort IV.
8.5. Locked WherePort IVs
There may be areas on a site where once a tagged asset has entered it should not be located using RTLS.
Movement along an assembly line may be more accurately tracked using only the WherePort IV signals.
