Decision Process : Set Service Area : Set Cell Site Type

Step 6 : Set Cell Site Type As we learned earlier, the type of cell site you use has an effect on the number of channels needed in the cell and the resulting traffic capacity. Following the example Let's look at both omni and sectored in terms of number of subscribers served. Omni There are 587 subscribers (determined in the last step). Sectorized For a sectorized site (as shown), we divide the 587 subscribers by our proposed sector arrangement. This shows us how many of our subscribers are served by each sector (alpha, beta, and gamma): Alpha   Beta   Gamma     pops   pops   pops 1/3 of 3184 1,062 1/2 of 1,667 834 1/2 of 4,398 2,199 1/10 of 5,674 568 1/2 of 105 = 53 pops * 1/2 (assume 1/2 the pops go to Beta) 26     1/2 of 105 pops = 53 pops (assume 1/2 of these pops go to Alpha) 27 434 vehicles * 1.5 pops/vehicle 651     333 vehicles *1.5 pops/vehicle 500                     Total: 2,157   1,511   2,199 Subscribers (10%) 216   152   220 Continue with Set System Load: Step 7 : Find Load/ Subscriber (Erlangs).
