Planning a Sample Site Page 45 of 102Meridian Companion Site Planning Reference ManualSample Site: Indoor cell center locationNote: When surveying a site, outdoor areas are surveyed before indoor areas,however there is no outdoor coverage required for Able Studio Inc. Foran example of outdoor coverage, refer to “Example outdoor cell centerlocation” on page 54.As shown in Figure 19, you use the floor plan of Able Studio Inc. to identifythe initial critical points P1, P2, P3, P4, P5 and P6. Using critical points P2and P6, you find that one cell cannot reach both critical points so you addcritical 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 boundaryvalue from P2, and -73 dBm from P1 and P8 to locate cell center 1C1. Youuse -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 thesecritical points.Figure 19 : Floor plan detailing cells 1C1 and 1C2With the CDT placed at 1C1, you find the cell boundary in the factory areausing -73 dBm. You confirm that 1C1 covers one other user’s office in thefactory 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, butcellcenterAbleStudioInc.criticalpointuser'sofficeP4P5P31C21C1P2P1P8P7P61C1-701C1-731C2-73-70-70-73-73-73-73restroomsandtelephoneswitchroom0 100ft2
