5 Experiment with different-sized cell clusters and discover why some cluster sizes are used more commonly than other sizes. Investigate and explain the advantages √ and disadvantages of different cell sizes. Derive the relationship D = R 3N, where D is the frequency reuse distance, R is the cell radius, and N is cell cluster size (number of cells in a cluster). 6 Create different-sized clusters with different R and find the frequency reuse distance (D) for each sample. 7 Prove that N = i2 + ij + j 2 , where N is the cell cluster size, i is the number of cells to be traversed in the i coordinate, and j is the number of cells to be traversed in the j coordinate from the originating cell.

The idea is to replicate this cluster a number of times to enhance the capacity of the system which refers to the number of users it can satisfactorily support. The degree of replication, which refers to the number of times a cluster is replicated, depends significantly on the cluster size. If the cluster size N is reduced without reducing the cell size, then a larger number of clusters will be required to cover the area. On the other hand, if it is increased, then a smaller number of clusters will be needed for coverage.

This is a database that stores information for the identification of mobile units. For example, it maintains a database electronic serial number that is unique to a mobile unit that prevents its theft and malicious use. It helps the network to deny any service to a stolen mobile unit. To handle the use of questionable equipment (stolen or fraudulent), a GSM maintains three types of lists identified as white, black, and gray. A white list stores all clean equipment identities, which are allowed to use the network, a gray list contains a clean but semifunctional unit (malfunctioning) that has difficulty in making a call, and the black list contains the identities of stolen or fraudulent units.
