With the CDT placed at 1C1, you find the cell boundary at -70 dBm in the
office area and -73 dBm in the factory area. You confirm that 1C1 covers two
users' offices in the factory area using -70 dBm. Two other users' offices are
within -73 dBm of 1C1 but they are not within -70 dBm of 1C1. So, 1C1 does
not cover these users' offices.
You mark with a check 20 users' offices as covered.
Figure 3 shows how you set up the CDT transceiver at critical points P4 and
P6. You find that one cell center cannot serve both critical points so you put
critical point P9 mid-way between P4 and P6. Using critical points P4, P5 and
P9 you find cell center 1C2. Because P6 is in an office area, you use -70 dBm
from P6; because P5 is in a user's office, you use -70 dBm from P5. P9 is not
in an office or office area, so you use -73 dBm from P9.
