14. If the cell boundary covers any other critical points, ignore these critical points when
proceeding with coverage deploying.
15.
Repeat the multi cell technique for the remaining area to be covered, from the
extremes of the coverage area toward the centre, until all of the floor is covered.

Use the subsequent critical points to fill in the coverage area between the first two
cells using the

Multiple floor deployment
This applies to deployment scenarios in the following situations:
•
The coverage area is on more than one floor.
• The floors are not adjacent to each other.
Checking for through-the-floor coverage
The first step in covering a multi-floor building is assessing the availability of through-the-floor
coverage. In buildings mainly constructed of wood, through-the-floor coverage can be used.
However, due to the construction of most modern buildings with raised floors, high metal
content, and reinforced concrete, through-the-floor coverage with DECT is limited.
Checking for through-the-floor coverage
1. Place the deployment tool in a middle floor of the site.
2. Go to the floor above the deployment tool and establish a link with the deployment
handset.
Follow the procedure on
Testing the deployment tool handset on page
84.
3. Measure the deployment contour as if the basestation was on this floor, instead of
the floor below.
