Sample Site: Indoor Cell Center Location - Nortel Meridian Companion Reference Manual

Sample Site: Indoor cell center location

Note: When surveying a site, outdoor areas are surveyed before indoor areas,
As shown in Figure 19, you use the floor plan of Able Studio Inc. to identify
the initial critical points P1, P2, P3, P4, P5 and P6. Using critical points P2
and P6, you find that one cell cannot reach both critical points so you add
critical point P8 and plan to cover the end of the building with two cells (see
"Double-cell technique" on page 33). You use -70 dBm as the cell boundary
value from P2, and -73 dBm from P1 and P8 to locate cell center 1C1. You
use -70 dBm from P7 and -73 dBm from P6 and P8 to locate cell center 1C2.
You use -70 dBm from P2 and P7 because there are users' offices at these
critical points.

With the CDT placed at 1C1, you find the cell boundary in the factory area
using -73 dBm. You confirm that 1C1 covers one other user's office in the
factory area using -70 dBm. Four users' offices are in the office area within
-70 dBm of 1C1. Two users' offices in the office area are within -73 dBm, but
however there is no outdoor coverage required for Able Studio Inc. For
an example of outdoor coverage, refer to "Example outdoor cell center
location" on page 54.
