8. Using the potential location for outdoor external antennas as a center
point, draw a circle on the floor plan with the radius equal to the range
found in Table 6, ": Range for outdoor external antennas (ft [m]),".
Remember to crop the arc of the circle around structures and earth
mounds.
Use the most suitable coverage area to select your cell center–either the
coverage area based on Table 6 or the coverage area determined in step 2
using the CDT.
Note: If you recommend external antennas, inform the customer that
you estimated the coverage area.
If you could not reach the critical point determine whether the customer
wants you to continue planning.
9. Repeat this procedure until you completely cover all of the outdoor
areas.
