Measure the radio signal strength by moving towards and away from the CS.
a.
Move to the CS until the radio signal strength level becomes "12".
b.
Move away from the CS and identify the CS coverage area within which the radio signal strength level
is greater than "8". Draw the area on the map.
c.
Move away from the CS and identify the CS coverage area within which the radio signal strength level
is greater than "3". Draw the area on the map.
3.
Repeat steps 1 and 2 for other CSs, and relocate the CSs when necessary.
a.
Overlap adjacent CS coverage areas where the radio signal strength level is "8" by 5 m to 10 m.
