When deciding where to install the CS, priority should be given to an error rate rather than a radio

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.
