Consider a hexagonal cellular geometry with cluster size K = 1 3 in Figure 1 . Assume shift parameters i and j where K 1

Consider a hexagonal cellular geometry with cluster size K=13 in Figure 1. Assume shift parameters i and j
where K1,2,3,dots,13AAijKK=13AA1,2,3,dots,13DACIdBRAMHz200kHzKK=13j.
(b) Find all the co-channel cells of cell A(i.e., cell 1in each cluster)in the first tier and label them with Ain
Figure 1.
(c) Show only one cluster labeled with cells using the notations above, i.e.,1,2,3,dots,13,so that adjacent cells
are labeled with no successive numbers to reduce the adjacent channel interference.
(d) Find the co-channel cell distance D from the desired cell A for the first-tier co-channel cells only.
(e) Also, find the value ofCIindB, considering only the first-tier co-channel cells, and that the mobile station
(MS)is located at a distance equal to the cell radius R away from the desired base station (BS)A. Note that
we consider that all cells are center-excited.
(f)If a mobile system is launched using the above cellular pattern in Figure 1 with the system bandwidth of50
MHz and the channel bandwidth of200kHz, then find the total number of channels per cell in the system,
as well as the capacity of the system (in terms of the number of calls served simultaneously)if the cluster
(with size K)is reused 5 times to cover a particular area.
Figure 1. A hexagonal cellular geometry with cluster size K=13.j. Consider cells in each cluster with size K are denoted as1,2,3,dots,13. And, the cell labeled with A
is cell number 1in each cluster. Assume that Ais the desired cell of concern.
(a) Find the values of i and jso that the aforementioned conditions for K are satisfied, i.e.,K=13 and j.
(b) Find all the co-channel cells of cell A(i.e., cell 1in each cluster)in the first tier and label them with Ain
Figure 1.
