SpotCell® 100 Series 11
3.3 Choosing a location for the SpotCell CU
The CU location is optimized, after the DU location and orientation has been optimized
and the DU has been mounted.
Generally, the CU should be mounted in a location as far as possible from the DU, while
being within the area where you require improved coverage.
If mounted on a ceiling, the unit should be facing downward, and in the center of the
area requiring coverage. When mounted facing down (horizontal) the coverage pattern is
circular for an open are with minimum obstructing walls. When mounting the CU
horizontally place it in the centre of the area needing improved coverage.
SC141/142 Note: The dual band CU should only be mounted vertically.
Figure 3.7: CU position and signal coverage
If mounted vertically on a wall, facing away from the wall the coverage pattern for an
open area with minimum obstructing walls is as shown in figure 3.7.
When mounting the CU vertically the unit should be positioned in the middle of the area
to be covered side-to-side, and off-centered front-to-back, as shown in figure 3.7. The
coverage area to the front is about twice that to the back of the CU if the wall it is
mounted on is a typical interior drywall partition wall, and not one constructed of a dense
material such as concrete. The unit should be mounted as high on the wall as possible.
Alternatively the CU can be mounted vertically by suspending it from the t-bars of a
suspended ceiling. T-bar clips are commercially available that permit this.
