Single and multiple floor deployment 75
Double cell deployment
Use the double cell technique only if referred here from the single cell
technique. Before beginning this technique, there must be two critical
points that one cell center cannot serve. Using the double cell technique,
find two locations for cell centers that cover three critical points, as shown
in Figure 44 "Double cell distance" (page 75).

Procedure 15
Double cell deployment
Step Action
1 Mark a third critical point midway between the two critical points
already identified.
2 Place the deployment tool at this midway critical point.
3 Establish a link.
4 Walk briskly into the coverage area within range of either of the
first two critical points until the cell boundary is reached.
5 Record the cell boundary by marking a small X on the floor plan
where the cell boundary is located.
6 Repeat step 4 and 5 several times, walking in different directions
to determine where the cell center can be located and still be
within range of the critical point.
7 Draw a thin contour line through the Xs to mark an arc on the
floor plan.
8 Repeat steps 2 through 5 walking into the coverage area of the
other of the first two critical points.
9 If the contour lines do not cross, or if the amount of overlap
between the cells is less than half the distance between the cell
