Detailed explanation-1: -Explanation: The capacity of a cellular system is directly proportional to the number of times a cluster is replicated in a fixed area. If the cluster size N is reduced while the cell size is kept constant, more clusters are required to cover a given area, and hence more capacity is achieved.
Detailed explanation-2: -System capacity is formally defined as the maximum of the product of the number of users per cell times the user spectral efficiency for a given maximum outage probability.
Detailed explanation-3: -If the cluster size is too large, there would be large co-channel cell separation, less interference level, and the channels available to the cells would decrease and so the capacity of the cell would reduce.
Detailed explanation-4: -The group of cells where the available frequency spectrum is totally consumed is called a cluster of cells. Two cells having the same number in the adjacent cluster, use the same set of RF channels and hence are termed as “Co-channel cells”.
Detailed explanation-5: -Explanation: Cluster is group of N cells. These cells use the complete set of frequency available for the cellular system at that location.
