they are not within -70 dBm of 1C1. Therefore, 1C1 does not cover these
users' offices.
Cells 1C1 and 1C2 cover seven users' offices, which you show with
checkmarks.
In Figure 20 you set up the CDT transceiver at critical points P3 and P5, and
find that one cell center cannot serve both critical points. You add critical point
P9 midway between P3 and P5. Using critical points P3 and P9, you find cell
center 1C3. Because P3 is in an office area, you use -70 dBm from P3.
Because P9 is also in an office area, you use -70 dBm from P9.

To find cell center 1C4 you use -70 dBm from critical points P9, P4 and P5.
With the CDT placed at 1C3, you use -70 dBm in the office area and -73 dBm
in the factory area.
With the CDT placed at 1C4, you use -70 dBm because the entire cell is within
an office area.
You mark with a check 29 users' offices as covered by cells 1C3 and 1C4.
In Figure 21 you add critical points P10 and P11. You find that one cell center
cannot serve both critical points, so you add critical point P12 midway
