Differing Floor Areas - Nortel Meridian Companion Reference Manual

Differing floor areas

This section shows what you need to consider when planning a building with
floors of different shapes.
Ensuring that cells are not too close
Links between Base Stations and a portable could be held too long as the user
moves between cells if the -45 dBm cell contours overlap. Keep areas of
overlap to a minimum, as shown in Figure 27.

cell center
-45 dBm contour
For each cell center:
1. Using the CDT, find the -45 dBm contour on the floor of the cell center
and on the floors above and below. If these contours overlap an atrium,
find the contours on all of the floors that are adjacent to the atrium.
2. Check that the -45 dBm contours of all the cells do not overlap each
other.
Note: The two cells do not have to be on the same floor. An overlap of

the -45 dBm contour can occur between two cell centers that are
two floors away.
