Double-cell technique
Note: Follow the double-cell technique only if you are referred here from the
single-cell technique.
Before you begin this technique you should have two critical points that one
cell center cannot serve. Using the double-cell technique, you find two
locations for cell centers that cover three critical points, as shown in Figure 15.

1. Mark a third critical point midway between the two critical points
already identified and place the CDT there.
2. Establish a link and walk briskly into the coverage area within range of
the first critical point until you reach the cell boundary.
Mark a small x on the floor plan where you reached the cell boundary.
3.
4. Repeat steps 2 and 3 several times, walking in different directions to get
an idea where the cell center can be located and still be within range of
the third critical point.
Draw a thin contour line through the x's on the floor plan.
5.
6. Repeat steps 2 to 5, walking into the coverage area of the second critical
point.
Note: If the contour lines do not cross, or if the point where they cross
is close to the edge of the coverage area between the midway
