36 Site planning and hardware deployment
To calculate the distance between DAP and handset, use the information
in Figure 10 "DECT range calculation chart" (page 36).
Using the building map, start at the possible DAP location. Move away
from the DAP location. Calculate the distance. When you encounter
an obstacle, calculate the insertion loss. Using the chart below, start
in the lower left corner (0,0), move horizontally, to the value for the
actual distance. Move vertically to the value for the insertion loss of
the encountered obstacle. If the curve in the chart is crossed, read the
maximum distance for that specific DAP in that situation. This gives the
cell size in that specific direction. Ensure that outside the calculated
range communication is possible but a good voice quality is no longer
guaranteed.
